Cost-effectiveness High Availability is a cost-effective option for deployments that provide high availability by using redundant SuperMassives. The owner of Virtual Group 1 is designated as the Master Node. 17. Check " Enable Stateful Synchronization ". When upgrading to SonicOS from a previous release that did not support Active/Active Clustering, it is highly recommended that you disable High Availability before exporting the preferences from an HA pair running a previous version of SonicOS. All Cluster Nodes share the same configuration, which is synchronized by the Master Node. Stateful HA Upgrade for TZ570 Series Enables Stateful High Availability feature #02-SSC-5891 List Price: $786.00 Our Price: $686.81. Designed for mid-sized organizations and distributed enterprise with SD-Branch locations, the TZ670 delivers industry-validated security effectiveness with best-in-class price-performance. When using logical monitoring, the HA pair will ping the specified Logical Probe IP address target from the Primary as well as from the Secondary SonicWALL. 2. . Minimal impact on bandwidth - Transmission of synchronization data is throttled so as not interfere with other data. When incremental synchronization fails, a complete synchronization is automatically attempted. If the Primary device loses connectivity, the Secondary SonicWALL transitions to Active mode and assumes the configuration and role of Primary, including the interface IP addresses of the configured interfaces. This Virtual Group functionality supports a multiple gateway model with redundancy. This chapter provides conceptual information and describes how to configure High Availability (HA) in SonicOS. In the case of BGP, where configuration may only be applied through the CLI, the configuration is distributed when the running configuration is saved with the write file CLI command. The HA port connection is used to synchronize configuration and firmware updates. The power is unplugged from the Primary appliance and it goes down. The Secondary appliance begins to send gratuitous ARP messages to the LAN and WAN switches using the same Virtual MAC address and IP address as the Primary appliance. No traffic is sent on X4 while all nodes are functioning properly. A subset of actions are allowed on the active firewall of Non-Master nodes, and even fewer actions are allowed on firewalls in the standby state. The result is asymmetric routing, in which the flow of packets in one direction go through a node different than that used for the return path. TZ670 NGFWs address the growing trends in web encryption, connected devices and high-speed . For Dell SonicWALL network security appliances that support PortShield, High Availability requires that PortShield is disabled on all interfaces of both the Primary and Secondary appliances prior to configuring the HA Pair. DPI is performed on the standby unit and then the results are returned to the active unit over the same interface. Currently, daisy chain switch mode is not supported. For example, say we have a deployment in which Virtual Group 1 is owned by Cluster Node 1 and Virtual Group 2 is owned by Cluster Node 2. In a cluster with two Cluster Nodes, one of which has a fault, naturally the other will take ownership. Active/Active Clustering Full Mesh configuration is an enhancement to the Active/Active Clustering configuration option and provides the highest level of availability possible with high performance. In a larger deployment, if Cluster Node 1 owns three or four Virtual Groups, traffic is distributed among the redundant ports traffic for Virtual Groups 1 & 3 is sent on X3, while traffic for Virtual Groups 2 & 4 is sent on X4. When a Cluster Node contains an HA pair, Stateful HA can be enabled within that Cluster Node, with the advantages of dynamic state synchronization and stateful failover as needed. Select the primary and secondary switch uplink as 23. NOTE: The local hosted Virtual Subnets will not be accessed through the Public IP once the route table is created on Azure. If Stateful HA is enabled for the pair, the failover occurs without interruption to network connections. Select the secondary management uplink and secondary switch uplink as 7. If the timestamps are out of sync and the Standby unit is available, a complete synchronization is pushed to the Standby unit. Typically this is handled by another device downstream (closer to the LAN devices) from the Active/Active Cluster, such as a DHCP server or a router. Within the cluster, all units are connected and communicating with each other. The Cluster Node consists of a Stateful HA pair, in which the Secondary firewall can assume the duties of the Primary unit in case of failure. Minimal impact on CPU performance - Typically less than 1% usage. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. You can unsubscribe at any time from the Preference Center. The configuration tasks on the High Availability > Monitoring page are performed on the Primary unit and then are automatically synchronized to the Secondary. "None" specifies that successive requests from the same client may be handled by any virtual machine. While all Cluster Nodes are up and processing traffic normally, redundant ports remain standby and are ready for use if the partner port goes down for any reason. The SonicWall is the high performing, secure Unified Threat Management (UTM) firewall. To set up HA with two switch management ports, Configuring HA and PortShield With a Common Uplink. The failing service is isolated as early as possible, and the failover mechanism repairs it automatically. Additional NAT policies can be configured as needed and can be made specific to a Virtual Group if desired. NOTE: The above configuration will deploy NSv_Azure_HA1, NSv_Azure_HA2 along with external Load balancer NSv_Azure_HA-ELB and internal Load balancer NSv_Azure_HA-ILB. The NSa 4700 has been built from the ground up with the latest hardware components, all designed to deliver multi-gigabit threat prevention throughput " even for encrypted traffic. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. When the primary unit is in Active HA mode, traffic between H1 and X3 is carried over the dedicated link between X3 and 12, and traffic between H3 and X4 is carried over the dedicated link between X4 and 13.When the secondary unit is in Active HA mode, traffic between H1 and X3 is carried over the dedicated link between X3 and 14, and traffic between H3 and X4 is carried over the dedicated link between X4 and 15.The link between the firewall interface, X0, and port 1 on the switch, carries the management traffic to manage the switch from the firewall. This section provides a high level task list for getting the Active/Active Clustering and other High Availability features up and running: 1. Preform the tasks described in Active/Standby and Active/Active DPI HA Prerequisites, including registering and associating the appliances on MySonicWALL and licensing the high availability features. Configuring HA and PortShields With Dedicated Uplink(s). The OSPF router-ID of each Cluster Node must be unique and will be derived from the router-ID configured on the Master node as follows: If the user enters 0 or 0.0.0.0 for the router-ID in the OSPF configuration, each nodes router-ID will be assigned the nodes X0 virtual IP address. We will go through the UI to cover how its done, and we will also perform an OS upgrade while a VoIP call is going through. There are two types of failover that can occur when Active/Active Clustering is enabled: High Availability failover Within an HA pair, the Secondary unit takes over for the Primary. 16. As part of the configuration for Active/Active Clustering, the serial numbers of other firewalls in the cluster are entered into the SonicOS management interface, and a ranking number for the standby order is assigned to each. Within each Cluster Node, Stateful HA keeps the dynamic state synchronized for seamless failover with zero loss of data on a single point of failure. Select the primary and secondary switch uplink as 1. In the event of the failure of the Primary SonicWALL, the Backup SonicWALL takes over to . This section describes the requirements for registering your Dell SonicWALL network security appliance and licensing the SonicWALL High Availability features. 2. This will cause traffic to be dropped by one or both Cluster Nodes since neither is seeing all of the traffic from the flow. ), and uses redundant upstream routers in addition to redundant switches. Virtual Group 1 traffic is sent on X3, while Virtual Group 2 traffic is sent on X4. To use the Active/Active DPI feature, the administrator must configure an additional interface as the Active/Active DPI Interface. Currently, a maximum of four Virtual Groups are supported. This section provides an introduction to the Active/Active Clustering feature. Stateful HA will provides Improved reliability & Faster Failover performance. A Virtual Group is only owned by one Cluster Node at a time, and that node becomes the owner of all the virtual IP addresses associated with that Virtual Group. - Provide and apply the recommended Firewalls design changes for enhancing performance, availability and provide more restriction on the . Redundant ports can be used along with Active/Active Clustering. 5. Under the Settings tab, type the username and password and from the drop down list under One-Time password method, select> TOTP . High Availability allows two identical SonicWALL security appliances running SonicOS Enhanced to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Backup unit. 15. The secure connection is pretty fast and reliable and keeps our data end to end encrypted. From a routing perspective, all Cluster Nodes appear as parallel routers, each with the virtual IP address of the Cluster Node's interface. Upon failure of the Primary unit, the Secondary unit will assume the Active role. Firmware or signature updates, changes to policies, and other configuration changes cannot be synchronized to other Cluster Nodes until the HA port connection is fixed. Load sharing is accomplished by configuring different Cluster Nodes as different gateways in your network. Active/Active failover always operates in Active/Active preempt mode. Layer-2 Bridged interfaces are not supported in a cluster configuration. Fill in all necessary information like Serial number, IP address, username, password. Failover - Describes the actual process in which the Standby unit assumes the Active role following a qualified failure of the Active unit. 5. After logging into the Master Node, monitoring configuration needs to be added on a per Node basis from the High Availability > Monitoring page. When Virtual MAC is enabled, it is always used even if Stateful Synchronization is not enabled. The failover to the Secondary SonicWALL occurs when critical services are affected, physical (or logical) link detection is detected on monitored interfaces, or when the SonicWALL loses power. Resolution. In each Cluster Node, only the active unit processes the SVRRP messages. The synchronization traffic is throttled to ensure that it does not interfere with regular network traffic. Primary - Describes the principal hardware unit itself. In addition to the two types of failover, the following feature provides protection against a single point of failure: Port Redundancy Although technically not a failover, a redundant port provides secondary by handling all the traffic if its partner has a fault. In this video I will deploy and test HA using the two most common deployments I have seen. "Client IP and protocol" specifies that successive requests from the same client IP address and protocol combination will be handled by the same virtual machine. Must be paired with a regular SonicWall NSa 2650 firewall. Navigate to the left menu. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. Preempt mode means that, after failover between two Cluster Nodes, the original owner node for the Virtual Group will seize the active role from the standby node after the owner node has been restored to a verified operational state. Active/Active Clustering also introduces the concept of Virtual Groups. We did test multiple fail-over tests but this was . Preempt - Applies to a post-failover condition in which the Primary unit has failed, and the Secondary unit has assumed the Active role. 1. Physical monitoring cannot be disabled for these interfaces. Select the firewall uplink as Interface X3. Configure per-unit IP addresses in the High Availability > Monitoring page. To enable link detection between the designated HA interfaces on the Primary and Backup units, leave the Enable Physical . Add new diagram here: SuperMassive network diagram. The Primary and Secondary SuperMassives unique LAN IP addresses cannot act as an active gateway; all systems connected to the internal LAN will need to use a virtual LAN IP address as their gateway. You can view these NAT policies in the Network > NAT Policies page. Standby - Describes the passive condition of a hardware unit. The virtual MAC address is created in the format 00-17-c5-6a-XX-YY, where XX is the interface number such as 03 for port X3, and YY is the internal group number such as 00 for Virtual Group 1, or 01 for Virtual Group 2. The Standby identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. The preferences can then be imported without potential conflicts after upgrading. The following table lists the information that is synchronized and information that is not currently synchronized by Stateful Synchronization. This is a technical video on SonicWall firewalls in high availability, HA for short. 8. Check "Enable Virtual MAC". This is a technical video on SonicWall firewalls in high availability, HA for short. The benefits of Active/Active Clustering include the following: All the firewalls in the cluster are utilized to derive maximum throughput, Can run in conjunction with Active/Active DPI to perform concurrent processing of IPS, GAV, Anti-Spyware, and App Rules services, which are the most processor intensive, on the standby firewall in each HA pair while the active firewall performs other processing, Load sharing is supported by allowing the assignment of particular traffic flows to each node in the cluster, All nodes in the cluster provide redundancy for the other nodes, handling traffic as needed if other nodes go down, Interface redundancy provides secondary for traffic flow without requiring failover, Both Full Mesh and non-Full Mesh deployments are supported. After a failover to the Secondary appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. SonicWall NSa 2650 High Availability. Configuring HA Using Two Switch Management PortsYou can connect X0 of the primary and secondary firewalls directly to the ports on the switch. The link between the firewall interface serving as the PortShield host and the switch is set up as a dedicated uplink.HA Pair Using One Switch Management Port Topology shows a firewall HA pair with a switch and one dedicated link: The firewall interfaces, X3 and X4, on the primary unit are connected to ports 12 and 13 on the switch. X3 and X4 are configured as PortShield hosts. Similarly, the firewall interfaces X3 and X4 on the secondary unit are connected to ports 14 and 15 on the switch. Ports 12 and 14 on the switch are port shielded to X3 with the dedicated uplink option enabled. Ports 13 and 15 on the switch are port shielded to X4 with the dedicated uplink option enabled. Ports 2 and 4 are port shielded to X3. Ports 3 and 5 are port shielded to X4. Physically connect the designated HA ports from the Primary to the Secondary HA unit. The Primary appliance synchronizes with the Secondary appliance. This section provides an introduction to the Stateful Synchronization feature. To configure High Availability on the Primary SonicWall, perform the following steps: Login to the SonicWall Management Interface. The High Availability virtual MAC address functionality is not supported when Active/Active Clustering is enabled. A redundant switch can be deployed anywhere in the network depending on the need for high availability. 17. If both units can successfully ping the target, no failover occurs. HA Conversion License to Standalone Unit for TZ570 Series 6. Physically connect an additional interface between the two appliances in each HA pair if you plan to enable Active/Active DPI. You can view these virtual IP addresses in the Network > Interfaces page. The alternative Cluster Node might already be processing traffic comparable in amount to the failed unit, and could become overloaded after failover. As with OSPF and RIP, configuration changes made on the Master node will be applied to all other Cluster Nodes. If neither unit in the HA pair can connect to the device, the problem is assumed to be with the device and no failover will occur. For example, you could use a smart DHCP server which distributes the gateway allocation to the PCs on the directly connected client network, or you could use policy based routes on a downstream router. To set up HA with a common uplink:For switch 1: This field is for validation purposes and should be left unchanged. Routers forwarding packets to networks through the cluster may choose any of the Cluster Nodes as the next-hop. This section provides conceptual information and describes how to configure High Availability (HA) in SonicOS. SVRRP is used to communicate Virtual Group link status and ownership status to all Cluster Nodes in the cluster. Firewall interfaces that serve as PortShield hosts are connected to a separate switch (not necessarily a switch) and not the same switch connected to the active and standby units. A Redundant Port field in the Network > Interfaces > Edit Interface page becomes available when Active/Active Clustering is enabled. When the PC user attempts to access a Web page, the Secondary appliance has all of the users session information and is able to continue the users session without interruption. Power down all the units except the unit that is to be designated as the Primary unit in Cluster Node 1. Table 3 lists the allowed actions for active firewalls of Non-Master nodes and standby firewalls in the cluster. In the event of the failure of an entire Cluster Node, the failover will be stateless. The High Availability pair uses the same LAN and WAN IP addressesregardless of which appliance is currently Active. The Primary identifier is a manual designation, and is not subject to conditional changes. High Availability. And the HA deployment I usually see in enterprise: Two firewall, two switches stacked using LACP providing no single point of failure. Enabling Preempt will cause the Primary unit to seize the Active role from the Secondary after the Primary has been restored to a verified operational state. Featuring a high port density (including 16 x 1GbE ports and three x 10 GbE ports), the solution supports network and hardware redundancy with high . Also, X0 on the primary as well as the secondary is ensured to be connected to port 1 of the switch (for example, via a hub) so that when the secondary firewall becomes the active unit, the switch can be managed via the linkbetween the firewall interface X0 on the secondary and port 1 of the switch. The owner of Virtual Group 1 is designated as the Master Node, and is responsible for synchronizing configuration and firmware to the other nodes in the cluster. 8. Active - Describes the operative condition of a hardware unit. Thank You. SonicWall TZ570 High Availability SonicWall TZ570 High Availability Appliance #02-SSC-5694. Login as an administrator to the SonicOS user interface on the Primary SonicWall. Layer 2 broadcasts inform the network devices of the change in topology as the Cluster Node which is the new owner of a Virtual Group generates ARP requests with the virtual MACs for the newly owned virtual IP addresses. Both appliances must be the same SonicWALL model. The Primary and Secondary appliances are continuously synchronized so that the Secondary can seamlessly assume all network responsibilities if the Primary appliance fails, with no interruptions to existing network connections. To create a free MySonicWall account click "Register". When more than two Cluster Nodes are configured in a cluster, these factors determine the Cluster Node that is best able to take ownership of the Virtual Group. Please can anyone provide step-by-step tutorial for configuring a high availability cluster (active-standby) with two Sonicwall 4650 firewalls. Set User Authentication Method to RADIUS. NSa 4600, 4600 High Availability: Specs . Login to the Primary unit in Cluster Node 1, leaving other units down. Active/Active failover is stateless, meaning that network connections are reset and VPN tunnels must be renegotiated. Physically connect the LAN and WAN ports of all units to the appropriate switches. Select the primary and secondary management uplink as 1. 6. Figure 50:15 4-Unit Full Mesh Deployment, You can also configure a Full Mesh deployment using only two firewalls, one per Cluster Node. When Active/Active Clustering is enabled, HA monitoring configuration is supported for the HA pair in each Cluster Node. No routing updates are necessary for downstream or upstream network devices. HA requires one SonicWALL device configured as the Primary SonicWALL, and an identical SonicWALL device configured as the Secondary SonicWALL. Palo Alto Networks. The management IP address of the Secondary unit is used to allow license synchronization with the SonicWALL licensing server, which handles licensing on a per-appliance basis (not per-HA pair). Active/Active DPI can be enabled, providing increased throughput within each Cluster Node. Click Manage in the top navigation menu. By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. The High availability is configured in stateless mode since stateful does not work with PPPoE. These rules should be the same as the default rules created between trusted and non-trusted zoned interfaces. Figure 50:13 Active/Active Clustering Topology. 17. Select the primary and secondary management uplink as 1. Create a full mesh configuration of NAT rules in the cluster so every interface-pair has a NAT rule which replaces the source IP address in the packet with the virtual IP of the egress interface. All rights Reserved. Configuring monitoring IP addresses for both units in the HA pair allows you to log in to each unit independently for management purposes. There are two ways to avoid asymmetric routing paths: 1. The self-checking mechanism is managed by software diagnostics, which check the complete system integrity of the SonicWALL device. After Active/Active Clustering is enabled, you must select the Virtual Group number during configuration when adding a VPN policy. Select the firewall uplink as Interface X2. Worked on configuring and troubleshooting Nodes, Pools, Profiles, Virtual Servers, SSL Certificates, iRules, and SNATs on the F5 Big IPs using the Web GUI and CLI; Involved in Network Designing, Routing, DNS, IP subnetting, TCP/IP . Note that non-management traffic is ignored if it is sent to one of the monitoring IP addresses. I do have switch in between Firewall & ISP Modem. Afterwards, switch to the Authentication tab. When Virtual Group 1 or any Virtual Group is created, default interface objects are created for virtual IP addresses with appropriate names, such as Virtual Group 1 or Virtual Group 2. Optionally, if you plan to use redundant ports for the LAN/WAN ports, connect the redundant ports to the appropriate switches. In the backup SonicWall text box, enter the backup firewall's serial number as shown on the bottom (or back) of the backup unit, then click apply. It features both inbuilt and an expandable storage of up to 256GB, that enables various features including logging, reporting, caching, firmware backup and more. Read Full Review. Data can be securely accessed through any device such as Windows, IOS, macOS, and many more devices. When the full mesh NAT rules are in place, the forward and reverse paths of flows transiting the cluster will always flow through the same Cluster Node (or the current owner of the Cluster Nodes primary virtual IP addresses). It is an active-standby configuration where the Primary appliance handles all traffic. Add to Cart. The original owner will have a higher priority for a Virtual Group due to its higher ranking if all virtual IP interfaces are up and the link weight is the same between the two Cluster Nodes. Has any one experience with a situation like this? One mention: when you power on the HA appliance for the first time, it is factory default and just like every SonicWall appliance, it is DHCP on X0. This field is for validation purposes and should be left unchanged. 7. Hi @Jour I can only speak for Gen6 in HA with PPPoE and there it usually takes 1-2 Minutes when the failover happens. In the case of failure of the HA port connection, SVRRP heartbeat messages are sent on the X0 interface. Note Before performing the procedures described in this section, ensure that you have completed the prerequisites described in Active/Standby and Active/Active DPI HA Prerequisites. In general, any network advertised by one node will be advertised by all other nodes. On Cluster Node ID 2 set the Virtual Group 1 Rank as Standby and Virtual Group 2 Rank as Owner. To use the switch with HA, you must first deploy the firewalls in high availability, and then add the switch. Because the appliances are using the same IP address, when a failover occurs, it breaks the mapping between the IP address and MAC address in the ARP cache of all clients and network resources. Hopefully this isn't getting worse with Gen7 because I'am somewhat before replacing some Gen6 Installations, including HA. 7. Configure settings in the High Availability > Advanced page. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. The enable virtual mac option is enabled and there is a switch between the ISP modem and the HA setup. The SonicWall TZ670 is a desktop-form-factor next-generation firewall (NGFW) with 10 Gigabit Ethernet interfaces. This chapter contains the following main . The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. A Virtual Group can also be thought of as a logical group of traffic flows within a failover context, in that the logical group of traffic flows can failover from one node to another depending upon the fault conditions encountered. Qualification of failure is achieved by various configurable physical and logical monitoring facilities described throughout the Task List section. Note Because all Cluster Nodes shares the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). This provides load sharing. Note All Cluster Nodes in the Active/Active cluster share the same configuration. NAT policies are automatically created for the affected interface objects of each Virtual Group. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. You need to configure these virtual IP addresses on the Network > Interfaces page. 4. Next-generation firewall for SMB, Enterprise, and Government, Comprehensive security for your network security solution, Modern Security Management for todays security landscape, Advanced Threat Protection for modern threat landscape, High-speed network switching for business connectivity, Protect against todays advanced email threats, Next-generation firewall capabilities in the cloud, Stop advanced threats and rollback the damage caused by malware, Control access to unwanted and unsecure web content, SSLVPN Timeout not working - NetBios keeps session open, Configuring a Virtual Access Point (VAP) Profile for Internal Wireless Corporate Users, How to hide SSID of Access Points Managed by firewall. Start up the other units in the Active/Active cluster. The latter is the High Availability > Monitoring page. Active/Active failover If all the units in the owner node for a Virtual Group encounter a fault condition, then the standby node for the Virtual Group takes over the Virtual Group ownership. Click MANAGE in the top navigation menu. When the Active/Active Clustering configuration is applied, up to three additional Virtual Groups are created, corresponding to the additional Cluster Nodes added, but virtual IP addresses are not created for these Virtual Groups. This chapter provides conceptual information and describes how to configure High Availability (HA) in SonicOS. Select the primary and secondary management uplink as 21. MUST BE PAIRED WITH A REGULAR SonicWall NSa 3650 FIREWALL. These NAT policies extend existing NAT policies for particular interfaces to the corresponding virtual interfaces. 1. For increased performance in an Active/Active cluster, enabling Active/Active DPI is recommended, as it utilizes the standby firewall in the HA pair for Deep Packet Inspection (DPI) processing. Virtual MAC for reduced convergence time after failover The Virtual MAC address setting allows the HA Pair to share the same MAC address, which dramatically reduces convergence time following a failover. Load Balancer health probes originate from the IP address 168.63.129.16 and must not be blocked for probes to mark up your instance. NOTE: Remote Desktop Service TCP port 3389 has been used for the Demo purpose. The traffic for the Virtual Group is processed only by the owner node. How to Configure Stateful Active-Standby High Availability in Gen6 UTM Appliances By pointing your websites and your customer's websites to our high availability name servers you can ensure connections enter the network at the closest possible point to your location and your customers. Currently working as a Resident Engineer at MOMRAH: - Perform full assessment for the PANW Panorama and NGFW deployment design and configuration. Select Active/Active Clustering Link/Interface under HA | Settings | HA Interfaces. All clients and remote sites continue to use the same Virtual MAC address and IP address without interruption. The PortShield hosts X0 are connected to a different switch (which could be a SonicWall switch or any other vendors switch) to avoid looping of packets. There are two factors in determining Virtual Group ownership (which Cluster Node will own which Virtual Group): Rank of the Cluster Node The rank is configured in the SonicOS management interface to specify the priority of each node for taking over the ownership of a Virtual Group. This is in contrast to traditional IP routing in which each packet in a flow may technically be forwarded along a different path as long as it arrives at its intended destination the intervening routers do not have to see every packet. 6. HA provides a way to share SonicWALL licenses between two SuperMassives when one is acting as a high availability system for the other. Configure Virtual Group IP addresses on the Network > Interfaces page. At this point, the redundant port X4 begins to be used for load sharing. By integrating automated and dynamic security . All actions are allowed for admin users with appropriate privileges on the active firewall of the Master Node, including all configuration actions. Dynamic WAN clients (L2TP, PPPoE, and PPTP), Deep Packet Inspection (GAV, IPS, and Anti Spyware), IPHelper bindings (such as NetBIOS and DHCP), Dynamic ARP entries and ARP cache timeouts. 14. 3. In case of a fault condition on one of the firewalls in this deployment, the failover is not stateful since neither firewall in the Cluster Node has an HA Secondary. The HA feature has a thorough self-diagnostic mechanism for both the Primary and Secondary SuperMassives. With Active/Active Clustering, you can assign certain traffic flows to each node in the cluster, providing load sharing in addition to redundancy, and supporting a much higher throughput without a single point of failure. A customer of us have a TZ670 in High Availability setup with a PPPoE fiber internet connection. Click Device in the top navigation menu. Configure per-unit IP addresses in the High Availability > Monitoring page. Configure IP addresses for the desired interfaces on the Network > Interfaces page. Create a User. TIP: Session persistence specifies that traffic from a client should be handled by the same virtual machine in the backend pool for the duration of a session. 3. In general, any network advertised by one node will be advertised by all other nodes. The PortShield members should also be connected to ports on the switch. Configure Virtual Group IP addresses on the Network > Interfaces page. Port redundancy, in which an unused port is assigned as a secondary to another port, provides protection at the interface level without requiring failover to another firewall or node. Note When HA Monitoring/Management IP addresses are configured only on WAN interfaces, they need to be configured on all the WAN interfaces for which a Virtual IP address has been configured. Stateful HA is not required, but is highly recommended for best performance during failover. Stateful Synchronization provides dramatically improved failover performance. Configuring Active/Active Clustering and HA. Login to the Primary unit, leaving other units down. For larger deployments, the cluster can include eight firewalls, configured as four Cluster Nodes (or HA pairs). This document describes the configuration options for all High Availability settings, whether they pertain to Active/Active Clustering or only to the HA pair. Configure the Mode as "Active / Standby". The Master Node is also responsible for synchronizing firmware to the other nodes in the cluster. The remaining processing is performed on the active unit. The SonicWall Network Security Appliance (NSA) series combines the patented SonicWall Reassembly Free Deep Packet Inspection (RFDPI) engine with a powerful and massively scalable multi-core architecture to deliver intrusion prevention, gateway anti-virus, gateway anti-spyware, and application intelligence and control for businesses of all sizes. Copyright 2022 SonicWall. The same interface can have multiple virtual IP addresses, one for each Virtual Group that is configured. Fyi, I am using stateful HA (Gen6) with 2 PPPoE interface and its working fine & the fail-over happening in 1-2min. The Virtual MAC setting is available even if Stateful High Availability is not licensed. Dynamic state is not synchronized across Cluster Nodes, but only within a Cluster Node. Cluster Node management and monitoring state messages are sent using SVRRP. This means that pre-existing network connections must be rebuilt. LabTech was the RMM software. On a particular interface, virtual IP addresses for Virtual Group 1 must be configured before other Virtual Groups can be configured. NOTE: Stateful Failover will not be available in the above setup. This KB explains how SonicWall switches can be deployed with the SonicWall UTM devices in high availability mode.The switches can be deployed with one or two dedicated uplinks and also with common uplinks. The IP address set in the Primary IP Address or Secondary IP Address field is used as the source IP address for the ping. Full Mesh deployments provide a very high level of availability for the network, because all devices have one or more redundant partners, including routers, switches, and security appliances. If both cannot successfully ping the target, no failover occurs, as the SonicWALLs will assume that the problem is with the target, and not the SonicWALLs. The maximum number of Cluster Nodes in a cluster is currently limited to four. 4. A Cluster Node can consist of a Stateful HA pair, a Stateless HA pair or a single standalone unit. A Virtual Group is a collection of virtual IP addresses for all the configured interfaces in the cluster configuration (unused/unassigned interfaces do not have virtual IP addresses). This greatly simplifies the failover process as only the connected switches need to update their learning tables. Select the primary and secondary switch uplink as 1. If you choose to make X5 the Active/Active DPI Interface, you must physically connect X5 on the active unit to X5 on the standby unit in the HA pair. CAUTION:Load Balancer uses a distributed probing service for its internal health model. However, while the HA port connection is down, configuration is not synchronized. #01-SSC-2007. Note Default NAT policies will be created automatically, so there is no need to configure NAT policies for Virtual Groups in the Network > NAT Policies page. Add to Cart for Pricing. MGMT interfaces and HA: The ACTIVE unit will always listen on what is configured for the MGMT interface on the Manage | Network | Interfaces page | "IP Address . If the timestamps are in sync and a change is made on the Active unit, an incremental synchronization is pushed to the Standby unit. Certain packet flows on the active unit are selected and offloaded to the standby unit on the Active/Active DPI Interface. When both High Availability failover and Active/Active failover are possible, HA failover is given precedence over Active/Active failover for the following reasons: HA failover can be stateful, whereas Active/Active failover is stateless. Do you have any VLAN's configured on the WAN switch? Below are the articles which can help with the configuration: SonicWALL NSA 3500 in HA setup with BGP for ISP automatic failover. shows a diagram of a 4-unit Full Mesh deployment.

SonicWall NSa 3650 High Availability. Under normal operating conditions, the Secondary unit operates in an Standby mode. Login to each unit using the per-unit IP address, and click Register and synchronize licenses with the MySonicWALL Licensing server. Update network diagram: SuperMassive network diagram. There is a weighting mechanism on both sides to decide which side has better connectivity, used to avoid potential failover looping. A customer of us have a TZ670 in High Availability setup with a PPPoE fiber internet connection. For example, connect X4 on the Primary unit to X4 on the Secondary. From a routing perspective, all Cluster Nodes will appear as parallel routers with the virtual IP address of the Cluster Nodes interface. Click Configure icon for an interface on the LAN, such as X0. Enable Active/Active DPI and configure the appropriate interface as the Active/Active DPI Interface. Click on Save to update the active directory admin for your Azure SQL Server. The interface must be the same number on both appliances. The following DPI services are affected: Active/Active DPI taps into the unused CPU cycles available in the standby unit, but the traffic still arrives and leaves through the active unit. The standby firewall in an HA pair is lightly loaded and has resources available for taking over the necessary processing, although it may already be handling DPI traffic if Active/Active DPI is enabled. If each Cluster Node is an HA pair, the cluster will include eight firewalls. Thus, Virtual Group 1 will include virtual IP addresses for X0, X1, and any other interfaces which are configured and assigned to a zone. Note The High Availability > Monitoring page applies only to the HA pair that you are logged into, not to the entire cluster. All other network devices continue to use the same virtual MAC addresses and do not need to update their ARP tables, because the mapping between the virtual IP addresses and virtual MAC addresses is not broken. If Cluster Node 2 goes down, Virtual Group 2 is now also owned by Cluster Node 1. The Secondary unit does not receive heartbeat messages from the Primary appliance and switches from Standby to Active mode. . Engineer all networks and routers connected to the cluster such that packet forwarding will always result in symmetric paths in respect to the virtual IP addresses used in the cluster. For example, a redundant switch might be deployed on the WAN side if traffic passing through it is business-critical. See Licensing High Availability Features. A virtual MAC address is associated with each virtual IP address on an interface and is generated automatically by Sonic OS. The Gen 7 TZ series are highly scalable, with high port density of up to 10 ports. Note For interfaces with configured virtual IP addresses, Active/Active physical monitoring is implicit and is used to calculate the Virtual Group Link Weight. OSPF is supported with Active/Active Clustering. This is different from HA monitoring. 7. This section contains the following main sections: Stateful Synchronization provides the following benefits: Improved reliability - By synchronizing most critical network connection information, Stateful Synchronization prevents down time and dropped connections in case of appliance failure. SonicWall NSA Series - High Availability. If the owner node for a Virtual Group encounters a fault condition, one of the standby nodes will become the owner. Resolution. This section describes the current limitations and special requirements for Active/Active Clustering configurations with regard to routing topology and routing protocols. Secondary - Describes the subordinate hardware unit itself. The two ports must be physically connected to the same switch, or preferably, to redundant switches in the network. In case of a failover, GMS administration continues seamlessly, and GMS administrators currently logged into the appliance will not be logged out, however Get and Post commands may result in a timeout with no reply returned. For more information about Full Mesh deployments, see the Active/Active Clustering Full Mesh Deployment Technote. Before you can enable Active/Active Clustering, Stateful Synchronization, and Active/Active DPI, these features must be licensed. Clicking the button opens the RADIUS Configuration window. This ensures that the Secondary appliance is always ready to transition to the Active state without dropping any connections. The above deployment is an Active/Active HA. 5. HA allows two identical SuperMassives running SonicOS to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Secondary unit. License Synchronization with SonicWALL License Manager, HA Synchronize Settings (syncs settings to the HA peer within the node), HA Synchronize Firmware (syncs firmware to the HA peer within the node), Authentication tests (such as test LDAP, test RADIUS, test Authentication Agent). HA monitoring can be configured for both physical/link monitoring and logical/probe monitoring. Navigate to network -> interfaces and look for the high availability HA . Navigate to high availability and enable it by ticking on the high availability check box and clicking on the apply button. For communication between Cluster Nodes, a new protocol called SonicWALL Virtual Router Redundancy Protocol (SVRRP) is used. The following features are not supported when Active/Active Clustering is enabled: The following features are only supported on Virtual Group 1: The Active/Active Clustering feature is not backward compatible. Fill in all necessary information like Serial number, IP address, username, password. HIGH AVAILABILITY NETWORK . Expand Users and select Settings. The Secondary SonicWALL maintains a real-time mirrored configuration of the Primary SonicWALL via an Ethernet link between the designated HA ports of the appliances. This allows synchronization of licenses (such as the Active/Active Clustering or the Stateful HA license) between the standby unit and the SonicWALL licensing server. Virtual Group Link Weight of the Cluster Nodes This is the number of interfaces in the Virtual Group that are up and have a configured virtual IP address. The Standby unit assumes the Active role in the event of determinable failure of the Active unit. CAUTION:The auto-authorize option cannot be used while the firewall is in HA.There are two ways to configure HA units with dedicated uplinks: Configuring HA Using One Switch Management Port. 2. When Stateful Synchronization is enabled, the Primary appliance actively communicates with the Secondary to update most network connection information. 5. The Secondary appliance must issue an ARP request, announcing the new MAC address/IP address pair. Select Active/Active DPI on the High Availability > Settings page. Configure settings in the High Availability > Advanced page. 10. High_Availability. When Active/Active Clustering is enabled for the first time, the configured IP addresses for the interfaces on that firewall are converted to virtual IP addresses for Virtual Group 1. Click CONFIGURE RADIUS on the right. 11. High Availability (HA) allows two identical firewalls running SonicOS to be configured to provide a reliable, continuous connection to the public Internet. Physical interface monitoring enables link detection for the monitored interfaces. If a link fails or a port is disconnected on the active unit, the standby unit in the HA pair will become active. Active/Active Clustering configuration can include configuring Virtual Group IDs and redundant ports. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. Yes 3 VLAN has been configured for each WAN connection. Each Virtual Group has one Cluster Node acting as the owner and one or more Cluster Nodes acting as standby. Note When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off. 3. Under normal operating conditions, the Primary hardware unit operates in an Active role. By default, the Virtual MAC address is provided by the SonicWALL firmware and is different from the physical MAC address of either the Primary or Secondary appliances. The link is sensed at the physical layer to determine link viability. There are four High Availability pages in the SonicOS management interface. NOTE:The Firewall Uplink and Switch Uplink options are set the same in this configuration to support the redundant firewalls. Active/Active Clustering Full-Mesh Overview, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh, Configuring Network DHCP and Interface Settings, Registering and Associating Appliances on MySonicWALL. Do you also have a switch between ISP modem and SonicWALL's? When Active/Active Clustering is initially enabled, the existing IP addresses for all configured interfaces are automatically converted to virtual IP addresses for Virtual Group 1. When a failover occurs, all routes to and from the Primary appliance are still valid for the Secondary appliance. 2. There are two types of synchronization for all configuration settings: incremental and complete. ARM template deployment, click Deploy to Azure. Configure settings in the High Availability > Advanced page. BGP is supported in clusters, and will also appear as parallel BGP routers using the virtual IP address of the Cluster Nodes interface. Faster failover performance - By maintaining continuous synchronization between the Primary and Secondary appliances, Stateful Synchronization enables the Secondary appliance to take over in case of a failure with virtually no down time or loss of network connections. This eliminates the possibility of configuration errors and ensures the uniqueness of the Virtual MAC address, which prevents possible conflicts. Note Per-unit IP addresses (HA monitoring IP addresses) are required for all the units in the cluster either on Primary LAN or on Primary WAN Interfaces. Failure to periodically communicate with the device by the active unit in the HA pair will trigger a failover to the standby unit. You can use the following name servers to point websites too; au- dns .f2hcloud.com | 139.99.135.201 - Australia. If a second interface is physically connected, configure it as the Active/Active DPI Interface 2 for Active/Active DPI.

In this case, twoswitch ports are used on the switch for management traffic.HA Pair Using 2 Switch Management Ports Topology shows a firewall HA pair with a switch and two dedicatedlinks: X0 of the primary unit is connected to port 1. X0 of the secondary unit is connected to port 7.
