One way is to use a smart DHCP server which distributes the gateway allocation to the PCs on the directly connected client network. Enter the Cluster Node serial numbers. 2. Every device is wired twice to the connected devices, so that no single point of failure exists in the entire network. 2. A security ecosystem to harness the power of the cloud, Protect Federal Agencies and Networks with scalable, purpose-built cybersecurity solutions, Access to deal registration, MDF, sales and marketing tools, training and more, Find answers to your questions by searching across our knowledge base, community, technical documentation and video tutorials. The configured virtual IP address appears in the Interface Settings table. These ports are used for Cluster Node management and monitoring state messages sent over SVRRP, and for configuration synchronization. Default NAT policies are created by SonicOS when virtual IP addresses are added, and are deleted when the virtual IP is deleted. For example, when an SMTP session carries a virus attachment, SonicOS sends the SMTP client a 552 error response code, with a message saying the email attachment contains a virus. A TCP reset follows the error response code and the connection is terminated. Connecting the LAN and WAN Interfaces in a High Availability Deployment. Optionally, for port redundancy with Active/Active DPI, physically connect a second Active/Active DPI Interface between the two appliances in each HA pair. action as described above, then the action is logged on the active unit of the Stateful HA pair, rather than on the idle unit where the match action was detected. Deep Packet Inspection discovers network traffic that matches IPS signatures, virus attachments, App Rules policies, and other malware. As the Master Node synchronizes new firmware to other appliances in the cluster, secondary units are created on those appliances. The Cluster Nodes are configured with redundant ports, X3 and X4. The table displays the following information: If you have configured the Primary SonicWALL to send email alerts, you receive alert emails After the above deployment is connected and configured, CN1 will own Virtual Group1 (VG1), and CN2 will own Virtual Group 2 (VG2). Performed automation tasks on various Docker . 3. But, if one SonicWALL can ping the target but the other SonicWALL cannot, the HA Pair will failover to the SonicWALL that can ping the target. appliance and click the Accept Within the cluster, all units are connected and communicating with each other. This section describes the procedure for setting up an Active/Active Cluster Full-Mesh deployment. Figure 62:10 Active/Active Four-Unit Cluster. 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. Connect the cables as follows for the X1, X3 ports: a.Connect CN2-Primary Firewalls X1 to Switch C and X3 to Switch D. b.Connect CN2-Backup Firewalls X1 to Switch C and X3 to Switch D. c.Connect CN2-Primary Firewalls X1 to Switch D and X3 to Switch C. d.Connect CN2-Backup Firewalls X1 to Switch D and X3 to Switch C. a.Configure all the Switch ports connected to the X1,X3 interfaces to be in the same port-based VLAN. VPN policy configuration requires association with a Virtual Group when running in Active/Active Clustering mode. The Primary and Secondary SonicWALL SuperMassives unique LAN IP addresses cannot act as an active gateway; all systems connected to the internal LAN will need to use the virtual LAN IP address as their gateway. Select the interface for the HA Control Interface. If both physical monitoring and logical monitoring are disabled, Active/Active failover will occur on link failure or port disconnect. SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster. NAT policies are automatically created for the affected interface objects of each Virtual Group. Virtual Groups Owned Displays the Virtual Group number owned by each node in the cluster. The General tab is displayed. However, while the Active/Active Cluster links are down, configuration is not synchronized. page to connect to the SonicWALL server while accessing the Backup appliance through its management IP address. Management is only allowed on an interface when this option is enabled. This is the license keyset for the SonicWALL security appliance that you selected in For example, click the configure icon for X2. To see the core usage for all firewalls in the cluster, SonicWALL recommends viewing the Multi-Core Monitor page on the active unit of the Master node. Note For interfaces with configured virtual IP addresses, Active/Active physical monitoring is implicit and is used to calculate the Virtual Group Link Weight. Note A packet cannot be forwarded on an interface if a virtual IP address is not configured on it for the Virtual Group handling that traffic flow. That is, connect the primary port on Router A to Switch C and the backup port on Router A to Switch D. Connect the ports in the same way for Router B. f.: Shut down Router A while Router B is up and ready. On DEVICE | High Availability > Monitoring, you can configure both physical and logical interface monitoring: Failure to periodically communicate with the device by the Active unit in the HA Pair triggers a failover to the Standby unit. Physical interface monitoring enables link detection for the monitored interfaces. Configure the Mode as " Active / Standby ". You can tell that Active/Active DPI is correctly configured on your Stateful HA pair by generating 6. To configure monitoring on any of the other interfaces, repeat the above steps. Go to the High Availability > Monitoring page and follow the steps in Configuring Active/Active Clustering High Availability Monitoring. 3. 12. Note that this does not indicate that all the processing was performed on the active unit. In the left navigation pane, navigate to High Availability > Monitoring. The following configuration parameters should appear with their correct values in the Tech Support Report: Active/Active DPI Interface configuration. To enable link detection between the designated HA interfaces on the Primary and Secondary units, leave the Enable Physical Interface Monitoring checkbox selected. 4. Any network appliance that performs deep packet inspection or stateful firewall activity must see all packets associated with a packet flow. Figure 50:21 Log > View Page Showing High Availability Events, Configuring VPN and NAT with Active/Active Clustering. However, there is no restriction on which ports you use. In the setup described above, X2 is the redundant port of X0. Open Server Manager and click Manage -> Add Roles and Features: Click Next: Role-based or feature-based installation should be selected then click Next: Select the server you want to install this role then click Next: Select Active Directory Certificate Services then click Next: On the pop up window click the box Include management tools then. The Primary and Backup IP addresses configured on this page are used for multiple purposes: Configuring unique management IP addresses for both units in the HA Pair allows you to log in (If probing is desired on the WAN side, an upstream device should be used.) 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. You can use a dedicated switch or simply use some ports on an existing switch in your internal network. Check "Enable Virtual MAC". You can assign multiple virtual IP addresses to each interface, one per Virtual Group. Power down Switch A while Switch B is up and ready. If neither can successfully ping the target, no failover occurs, because it is assumed that the problem is with the target, and not the Dell SonicWALL network security appliances. On the Systems > Licenses page under Manual Upgrade, press Ctrl+V to paste the license keyset into the Or enter keyset text box. A Cluster Node can consist of a Stateful HA pair, a Stateless HA pair or a single standalone unit. You can configure a redundant port on the Advanced tab of the Edit Interface window. When live communication with SonicWALL's licensing server is not permitted due to network policy, The two ports must be physically connected to the same switch, or preferably, to redundant switches in the network. The same interface must be selected on each appliance. When finished with all High Availability monitoring configuration for the selected Cluster Node, click Apply. Connect all the HA links of all the firewalls into a port-based-VLAN on Switch E. 2. Clear the Enable DHCP Server checkbox. In the Primary IP Address field, enter the unique LAN management IP address of the Primary unit. 6. A remote access VPN is a temporary connection between users and headquarters, typically used for access to data center applications. Cable Switch A and Switch B together. Go to the High Availability > Advanced page and follow the steps in High Availability > Advanced. Some DPI match actions inject additional TCP packets into the existing stream. Try our. On the High Availability > Monitoring page, add the monitoring/management IP addresses either on X0 or X1 for each unit in the cluster. 12. In the Secondary IPv4 Address field, enter the unique LAN management IP address of the Secondary unit. In the VPN Policy window, both the Network and Advanced tabs have new configuration options for creating this association. 15.9 How to see which IP addresses the Squid proxy is listening on. For example, select X4 for the redundant port. Active/Active Clustering requires additional configuration of virtual IP addresses for additional Virtual Groups. 4. Active/Active Clustering Full-Mesh configuration is an enhancement to the Active/Active Clustering configuration option and prevents any single point of failure in the network. This includes firmware or signature upgrades, policies for VPN and NAT, and other configuration. In the right pane, find the rules titled File and Printer Sharing (Echo Request - ICMPv4-In) . Networking, LAN & WAN troubleshooting, Configuring, and managing devices like Firewalls, Routers, Manageable Switches, IP Phones. Connect the cables as follows for the X0, X2 ports: a.Connect CN2-Primary Firewalls X0 to Switch A and X2 to Switch B. b.Connect CN2-Backup Firewalls X0 to Switch A and X2 to Switch B. c.Connect CN2-Primary Firewalls X0 to Switch B and X2 to Switch A. d.Connect CN2-Backup Firewalls X0 to Switch B and X2 to Switch A. a.Configure all the Switch ports connected to the X0,X2 interfaces to be in the same port-based VLAN. Under DHCP Server Lease Scopes, select the checkbox at the top left corner of the table heading to select all lease scopes in the table. Then connect one port to Switch C and the other port to Switch D. Do a similar configuration for Router B. The steps for configuring Stateful Sync and Active-Active DPI do not apply. Go to the High Availability > Advanced page and follow the steps in High Availability > Advanced. I had an old SonicWALL TZ210 sitting around so I configured that to connect to Azure instead and did the same tests and saw the following speeds performing the same operation: As you can see the SonicWALL is significantly faster than the Draytek despite being an old model. Link Failures: Traffic should continue to flow in each of the following link failures: a. The Primary and Secondary Security Appliances unique LAN IP addresses cannot act as an active gateway; all systems connected to the internal LAN needs to use the virtual LAN IP address as their gateway. If the Routers do not have redundant port support, but have switching support then you create two ports in the same VLAN on Router A and assign an IP address to the VLAN instead of the port. When Active/Active Clustering is enabled, HA monitoring configuration is supported for the HA pair in each Cluster Node. You can tell that Active/Active DPI is correctly configured on your Stateful HA pair by generating a Tech Support Report on the System > Diagnostics page. When the SonicWALL SuperMassives in the Active/Active cluster have Internet access, each appliance in the cluster must be individually registered from the SonicOS management interface while the administrator is logged into the individual management IP address of each appliance. After enabling Active/Active DPI, the connected interface will have a Zone assignment of HA Data-Link. Compare. This means that pre-existing network connections must be rebuilt. The two units in each HA pair are also connected to each other using another interface (shown as the Xn interface). for the following settings: The Active/Active Clustering Node Status table is shown in To configure monitoring on any of the other interfaces, repeat the above steps. See the following: Comparing CPU Activity on Appliances in a Cluster, Verifying Settings in the High Availability > Status Page, Comparing CPU Activity on Appliances in a Cluster. 2 In the left navigation pane, navigate to High Availability > Monitoring. The IP address set in the Primary IP Address or Backup IP Address field is used as the source IP address for the ping. Set up IPsec VPN on HQ1 (the HA cluster): Go to VPN > IPsec Wizard and configure the following settings for VPN Setup : Enter a proper VPN name. Thus, Virtual Group 1 will include virtual IP addresses for X0, X1, and any other interfaces which are configured and assigned to a zone. Figure 62:12 Active/Active Two Node Cluster. Active/Standby High Availability Monitoring, The Primary and Secondary IP addresses configured on this page are used for multiple, As independent management addresses for each unit (supported on all physical interfaces), To allow synchronization of licenses between the Idle unit and the SonicWALL licensing, As the source IP addresses for the probe pings sent out during logical monitoring, Configuring unique management IP addresses for both units in the HA Pair allows you to log in, The management IP address of the Secondary/Idle unit is used to allow license synchronization, When using logical monitoring, the HA Pair will ping the specified Logical Probe IP address, To set the independent LAN management IP addresses and configure physical and/or logical. Clustering and Active/Active DPI. To enable link detection between the designated HA interfaces on the Primary and Backup, Optionally, to manually specify the virtual MAC address for the interface, select. Follow the procedure in this section to activate licenses from within the SonicOS user interface. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. In the Logical Probe IP Address field, enter the IP address of a downstream device on the LAN network that should be monitored for connectivity. shows the NAT policy automatically created for Virtual Group 2 on interface X1. Go to the High Availability > Monitoring page and follow the steps in Configuring Active/Active Clustering High Availability Monitoring. In the case of failure of the Active/Active Cluster links, SVRRP heartbeat messages are sent on the X0 interface. 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. Cable Switch C and Switch D together. These NAT policies extend existing NAT policies for particular interfaces to the corresponding virtual interfaces. Load Sharing and Multiple Gateway Support. The owner of Virtual Group 1 is designated as the Master Node. 3 Settings All firewall and other network devices are partnered for complete redundancy. It is also possible to check the status of the Backup SonicWALL by logging into the unique LAN DPI is performed on the standby unit and then the results are returned to the active unit over the same interface. We had a similar issue with our site-to-site VPN but both locations had static IPs. If the Primary SonicWALL subsequently resumes operation after that failure, and Preempt Mode has been enabled, the Primary SonicWALL takes over and another email alert is sent to the administrator indicating that the Primary has preempted the Backup. By default, Cluster Node 1 is the Owner of Group 1, and typically is ranked as Standby for Group 2. In the lower section of the page, shown in , the High Availability Status table displays the HA settings and status for each node in the cluster. All devices in the Cluster must be of same product model and be running the same firmware version. Primary IP Address Configuring Active/Active Cluster Full-Mesh 2-Unit Deployment. The Backup SonicWALL security appliance should quickly take over. 2. To configure Active/Active Clustering High Availability: 1. When finished with all High Availability configuration, click Accept. In the Interface Settings table, click the configure icon for the interface you want to configure. Feature Support Information with Active/Active Clustering. b. Select the Active/Active Cluster Link interface. Even if the Secondary unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System The IP address set in the Primary IP Address or Secondary IP Address field is used as the source IP address for the ping. This section describes two methods of verifying the correct configuration of Active/Active UTM, Comparing CPU Activity on Both Appliances, As soon as Active/Active UTM is enabled on the Stateful HA pair, you can observe a change in, You can tell that Active/Active UTM is correctly configured on your Stateful HA pair by. 4. But, if one appliance can ping the target and the other appliance cannot, failover will occur to the appliance that can ping the target. When the There is also a way to synchronize licenses for an HA Pair whose appliances do not have Internet access. Check " Enable Stateful Synchronization ". Benefits of Active/Active Clustering Full Mesh. In the Mode pull-down menu, select Active/Active DPI Clustering. VLAN interfaces can also have up to four virtual IP addresses. Log in to the SonicOS user interface using the individual LAN management IP address for the. In general, any network advertised by one node will be advertised by all other nodes. In the second row, enter the rank that Cluster Node 2 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. Cluster Node management and monitoring state messages are sent using SVRRP over the Active/Active Cluster links. Connect the cables as follows for the X0, X2 ports: a.Connect CN2-Primary Firewalls X0 to Switch A and X2 to Switch B. b.Connect CN2-Backup Firewalls X0 to Switch A and X2 to Switch B. c.Connect CN2-Primary Firewalls X0 to Switch B and X2 to Switch A. d.Connect CN2-Backup Firewalls X0 to Switch B and X2 to Switch A. a.Configure all the Switch ports connected to the X0,X2 interfaces to be in the same port-based VLAN. This Virtual Group functionality supports a multiple gateway model with redundancy. The IP address set in the Primary IP Address or Secondary IP Address field is used as the source IP address for the ping. When Active/Active DPI is enabled on a Stateful HA pair, you can observe a change in CPU utilization on appliances in the HA pair. pair takes over operation. But, if one SonicWALL can ping the target but the other SonicWALL cannot, the HA pair will failover to the SonicWALL that can ping the target. 6. These ports are used for Cluster Node management and monitoring state messages sent over SVRRP, and for configuration synchronization. Even if the standby unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System > Licenses page to connect to the SonicWALL server while accessing the Secondary appliance through its management IP address. See Configuring Active/Active Cluster Full-Mesh 2-Unit Deployment. In the Primary IP Address field, enter the unique LAN management IP address of the Primary unit. For example, Note The Active/Active virtual MAC address is different from the High Availability virtual MAC address. The preferences can then be imported without potential conflicts after upgrading. checkbox is selected on the High Availability> Advanced Note Because all Cluster Nodes share the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). The types of administrative actions that are allowed differ based on the state of the firewall in the cluster. For Active/Active Clustering, additional physical connections are required: Active/Active Cluster LinkEach Active/Active cluster link must be a 1GB interface. Allowing the SonicOS firmware to generate the Virtual MAC address eliminates the possibility of configuration errors and ensures the uniqueness of the Virtual MAC address, which prevents possible conflicts. On each Cluster Node, each primary and redundant port pair must be physically connected to the same switch, or preferably, to redundant switches in the network. System SonicPoints require a DHCP server to provide IP addresses to wireless clients, but the embedded SonicOS DHCP server is automatically disabled when Active/Active Clustering is enabled. 5. OTP deployment consists of a number of configuration steps, including preparing the infrastructure for OTP authentication, configuring the OTP server, configuring OTP settings on the Remote Access server, and updating DirectAccess client settings. 5. This allows the Backup unit to synchronize with the SonicWALL licensing server and share licenses with the associated Primary appliance. 3. I am trying to setup Site to site VPN . Configure the VG1 IP address on X0 as the gateway for a certain set of traffic flows and the VG2 IP address on X0 as the gateway for other sets of traffic flows. In the Logical Probe IP Address field, enter the IP address of a downstream device on the LAN network that should be monitored for connectivity. SVRRP is also used to synchronize configuration changes, firmware updates, and signature updates from the Master Node to all nodes in the cluster. c.Select CN1 as Owner for Virtual Group 1 and Standby for Virtual Group 2. d.Select CN2 as Owner for Virtual Group 2 and Standby for Virtual Group 1. f.: Enable Active/Active DPI with X6 and X7 as the two HA data ports. Navigate to the System > Diagnostics page. On the Advanced tab, you can select the Virtual Group number for the VPN Policy Group setting. Active/Active Clustering Full-Mesh Overview. This section describes two methods of verifying the correct configuration of Active/Active UTM, This field is for validation purposes and should be left unchanged. To enable interface monitoring On the High Availability > Settings page under Interface Monitoring, select Enable Interface Monitor. By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. d.Disconnect X6, the Active-Active DPI HA data interface. Synchronize Settings button, the Primary will automatically synchronize the settings to the Backup unit, causing the Backup to reboot. The management interface should, Now, power the Primary SonicWALL back on, wait a few minutes, then log back into the, If you are using the Monitor Interfaces feature, experiment with disconnecting each monitored, In some cases, it may be necessary to force a transition from the Active SonicWALL to the Idle, To force such a transition, it is necessary to interrupt the heartbeat from the currently Active, To restart the Active SonicWALL, log into the Primary SonicWALL LAN IP address and click, If the Preempt Mode checkbox has been selected for the Primary SonicWALL, the. c.Connect X6 of CN2-Primary to X6 of CN2-Backup with a Cross-over cable. 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. Configuring Active/Active Clustering Full Mesh. The HA port connection is used to synchronize configuration and firmware updates. Example: Active/Active Clustering Two-Unit Deployment. Verifying Settings in the High Availability > Status Page The High Availability > Status page provides status for the entire Active/Active cluster and for each Cluster Node in the deployment. Click the HA Interfaces tab. 2. Another method is by using policy based routes on a downstream router. Turn on all the other firewalls. Login as an administrator to the SonicOS user interface on the Primary SonicWALL. Typically, this should be a downstream router or server. Device Failures: Traffic should continue to flow through both Cluster Nodes in each of the following device failures: a. The SonicWALL also maintains an event log that displays the High Availability events in In the Mode pull-down menu, select Active/Active Clustering. 2. We are in need of connecting 1 office to another via VPN . .st0{fill:#FFFFFF;} Not Really. This is the Active/Active DPI Interface necessary for Active/Active DPI. You do not need to click the Synchronize For Template Type, choose Site to Site . Login to the Primary unit of the Cluster Node and navigate to the Network > Interfaces page. Note that Stateful High Availability is not supported on the SonicWALL TZ 200 Series. Deep Packet Inspection discovers network traffic that matches virus attachments, IPS Active/Standby High Availability Monitoring, Configuring Active/Standby High Availability Monitoring. Login to each firewall unit using the dedicated monitoring/management address and do the following: b.Synchronize the licenses with MySonicWALL. 2. 5. Successful High Availability synchronization is not logged, only failures are logged. Connecting the HA Ports for Active/Active Clustering. Verifying Settings in the High Availability > Status Page. See the following: On the active firewall of the Master node, the System > Diagnostics page with Multi-Core mason county press obituaries. Click on Add Users. 8. target from the Primary as well as from the Backup SonicWALL. . checkbox is selected on the High Availability> Advanced One advantage of this feature is that in case of a physical link failure, there is no need to do a device failover. SVRRP is used to communicate Virtual Group link status and ownership status to all Cluster Nodes in the cluster. You can specify a Virtual Group or select Any when creating custom NAT policies. On the Network > Interfaces page, you can configure additional virtual IP addresses for interfaces in a Virtual Group, and redundant ports for interfaces. In the VPN Policy window, both the Network and Advanced tabs have new configuration options for creating this association. SonicWall University is the place to view our certification course catalog, the ATP class schedule, and activate e-learning keys for online modules. You can also configure physical/link monitoring and logical/probe monitoring. 9. Repeat this procedure for the other appliance in the HA pair. HealthHub - Patient Engagement Solutions. The default is Virtual Group 1. 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. Active/Active failover always operates in Active/Active preempt mode. 15. A WAN interface failure can trigger either a WLB failover, an HA pair failover, or an Active/Active failover to another Cluster Node, depending on the following: WAN goes down logically due to WLB probe failure WLB failover, Physical WAN goes down while Physical Monitoring is enabled HA pair failover, Physical WAN goes down while Physical Monitoring is not enabled Active/Active failover, Routing Topology and Protocol Compatibility. When configuring a redundant port, the interface must be unused; that is, not assigned to any zone. Click DOWNLOAD. As soon as Active/Active UTM is enabled on the Stateful HA pair, you can observe a change in You can assign multiple virtual IP addresses to each interface, one per Virtual Group. For example, in a 4-node cluster, if the router-ID 10.0.0.1 was configured on the Master node, the router-IDs assigned would be as follows: RIP is supported, and like OSPF, will run on the RIP-enabled interfaces of each Cluster Node. You can follow the procedure in this section to view the license keyset on MySonicWALL and g.Shut down Router B while Router A is up and ready. 2. All settings will be synchronized to the Standby unit, and the Standby unit will reboot. This ensures seamless operation and it appears as if the DPI UTM processing was done on the active firewall. 7. 5. 7. and two false negatives that might give the impression that the idle unit is not contributing. You can also use URL filtering to enforce safe search settings for your users, and to prevent credential phishing based on URL category. signatures, Application Firewall policies, and other malware. Active/Active failover transfers ownership of a Virtual Group from one Cluster Node to another. The alternative Cluster Node might already be processing traffic comparable in amount to the failed unit, and could become overloaded after failover. For communication between Cluster Nodes, a new protocol called SonicWALL Virtual Router Redundancy Protocol (SVRRP) is used. When live communication with SonicWALL's licensing server is not permitted due to network policy, In a High Availability deployment without Internet connectivity, you must apply the license, Activating Licenses from the SonicOS User Interface. To enable link detection between the designated HA interfaces on the Primary and Secondary units, leave the Enable Physical Interface Monitoring checkbox selected. Enable Virtual MAC 4. 8. Sonicwall allow specific url. 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. Registering and Associating Appliances on MySonicWALL. This includes firmware or signature upgrades, policies for VPN and NAT, and other configuration. On the High Availability > Monitoring page, you can configure independent management IP addresses for each unit in the HA Pair, using either LAN or WAN interfaces. Connecting the HA Ports for Active/Active Clustering. Perform the procedure for each of the appliances in a High Availability Pair while logged into its individual LAN management IP address. This diagram shows a four-unit cluster. in the upper right corner. at the top of the window. NO_PROPOSAL_CHOSEN. See the following: Comparing CPU Activity on Appliances in a Cluster, Verifying Settings in the High Availability > Status Page, Comparing CPU Activity on Appliances in a 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. The security services settings will be automatically updated as part of the initial synchronization of settings. Later, when you click That is, associate the two appliances in the HA pair for Cluster Node 1, then associate the appliances in the HA pair for Cluster Node 2, and so on for any other Cluster Nodes. has not been enabled, or to force the Backup SonicWALL to become Active in order to do preventive maintenance on the Primary SonicWALL. Verifying Active/Active Clustering Configuration. A Cluster Node can also be a single firewall, allowing an Active/Active cluster setup to be built using two firewalls. An Active/Active Cluster is formed by a collection of Cluster Nodes. This section describes the physical connections needed for Active/Active Clustering and Active/Active DPI. 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. High Availability Status attachments, Application Firewall policies, and other malware. For example, These additional TCP packets are generated as a result of the DPI processing on the idle, If Active/Active DPI is enabled and DPI processing on the idle firewall results in a DPI match, Log > View Page Showing High Availability Events. You can view these virtual IP addresses in the Network > Interfaces page. You can assign an unused physical interface as a redundant port to a configured physical interface called the primary interface. To restart the Active SonicWALL, log into the Primary SonicWALL LAN IP address and click If the Primary SonicWALL is Active, the first line in the table indicates that the Primary SonicWALL is currently Active. After the above deployment is connected and configured, CN1 will own Virtual Group1 (VG1), and CN2 will own Virtual Group 2 (VG2). You can unsubscribe at any time from the Preference Center. Figure 50:24 VPN Policy Window - Advanced, NAT Policy Configuring with Active/Active Clustering. Optionally, for port redundancy with Active/Active DPI, you can physically connect a second Active/Active DPI Interface between the two appliances in each HA pair. Management is only allowed on an interface when this option is enabled. Dynamic state is not synchronized across Cluster Nodes, but only within a Cluster Node. Then, check to see if the test email arrives. 6. However, until you apply the licenses to the appliance, it cannot perform the licensed services. If creating a VPN Policy for a remote network, Virtual Group address objects may also be available. When finished with all High Availability configuration, click Accept. There are two ways to avoid asymmetric routing paths: 1. 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. In the Licenses > License Management page, type your MySonicWALL user name and password into the text boxes. Click on Windows.exe Under NetExtender Clients to download the program. On each of the Active firewalls in the Cluster Node, disconnect the X0 cable while X2 is connected. After logging into the Master Node, monitoring configuration needs to be added on a per Node basis from the High Availability > Monitoring page. SonicWALL. 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. If both units can successfully ping the target, no failover occurs. To verify that Primary and Backup SonicWALL security appliances are functioning correctly, From your management workstation, test connectivity through the Backup SonicWALL by, Log into the Backup SonicWALLs unique LAN IP address. If the owner node for a Virtual Group encounters a fault condition, one of the standby nodes will become the owner. setting is enabled. Note that this does not indicate that all the processing was performed on the active unit. The management IP address of the Backup/Idle unit is used to allow license synchronization Try to configure the PRTG SNMP SONICWALL SYSTEM HEALTH SENSOR, It will give you the sonicwall health as same as below; Connection Cache Used CPU Usage Downtime Memory Usage MitatOnge Cybersecurity Overlord Hi Jason, you can find the high availability sensors in the "SONICWALL-FIREWALL-TRAP-MIB.MIB" file at Sonicwall download center. 2. Failure to periodically communicate with the device by the Active unit in the HA Pair will trigger a failover to the Standby unit. Click OK. 7. If the Backup has taken over for the Primary, the status table indicates that the Backup is currently Active. No switch is necessary in this case. Optionally, you can deploy Active/Active Cluster Full-Mesh with 2 firewall units where each CN consists of only one firewall (no HA backup). 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. When a Cluster Node is a Stateful HA pair, Active/Active DPI can be enabled within the Cluster Node for higher performance. page, the SonicOS firmware automatically generates a Virtual MAC address for all interfaces. In previous sections we discussed the Active/Active Cluster Full-Mesh with 4 firewall units. When this option is enabled for an interface, a green icon appears in the interfaces Management column in the Monitoring Settings table on the High Availability > Monitoring page. Some DPI match actions inject additional TCP packets into the existing stream. Note Because all Cluster Nodes share the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). The Active/Active Clustering node status is displayed at the top of the page, and shows values for the following settings: Node Status Active or Standby for each node in the cluster, Primary A/A Licensed Yes or No for each node in the cluster, Secondary A/A Licensed Yes or No for each node in the cluster. Add the redundant port configuration (X2 as redundant port of X0, X3 as redundant port of X1). 5. The secure connection is pretty fast and reliable and keeps our data end to end encrypted. CPU activity goes down on the active unit, and goes up on the idle unit. From the left pane of the resulting window, click Inbound Rules . 8. If DPI UTM processing on the idle firewall results in a DPI match action as described above. SONIC_WALL_IP, 500 CISCO_IP, 500 VPN Policy: test. 9. The Redundant Port field is only available when Active/Active Clustering is enabled. Full Mesh is not required when deploying redundant ports or switches, but a Full Mesh deployment includes them. The High Availability > Status page provides status for the entire Active/Active cluster and for When using logical monitoring, the HA Pair pings the specified Logical Probe IP address target from the Primary as well as from the Secondary unit. 3. All Cluster Nodes share the same configuration as the Master node. 6. In the case of a two-unit Active/Active cluster deployment, where the two Cluster Nodes each have only a single appliance, you can connect the HA ports directly to each other using a cross-over cable. 6. when an SMTP session carries a virus attachment, SonicOS sends the SMTP client a 552 error response code, with a message saying the email attachment contains a virus. A TCP reset follows the error response code and the connection is terminated. Allowing the SonicOS firmware to generate the Virtual MAC address eliminates the possibility of configuration errors and ensures the uniqueness of the Virtual MAC address, which prevents possible conflicts. Under Tech Support Report, click Download Report. . In the second row, enter the rank that Cluster Node 2 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. When finished with all High Availability configuration, click Apply. If there is a physical link failure on the primary interface, the redundant interface can continue processing traffic without any interruption. When this option is enabled for an interface, a green icon appears in the interfaces Management column in the Monitoring Settings table on the High Availability > Monitoring page. On each of the Active firewalls in the Cluster Node, disconnect the X0 cable while X2 is connected. Configuring Active/Active Clustering High Availability Monitoring. You can start by registering a new appliance, and then choosing an already-registered unit to associate it with. Login to the Primary unit of the Cluster Node and navigate to the Network > DHCP Server page. Note The new virtual IP address must be in the same subnet as any existing virtual IP address for that interface. Every device is wired twice to the connected devices. For more information about the HA Monitoring settings, see About HA Monitoring. Do this after you have linked them in MySonicWall. 7. Power down Switch B while Switch A is up and ready. To exclude an appliance from a cluster, select None for the Virtual Group X Rank. Responses, or actions, are always sent out from the active unit of the Stateful HA pair running Active/Active DPI when DPI matches are found in network traffic. 9. Figure 62:11 Active/Active Two-Unit Cluster. If preempt mode is enabled, the Primary SonicWALL becomes the Active firewall and the Backup firewall returns to Idle status. Table 3 lists the allowed actions for active firewalls of Non-Master nodes and standby firewalls in the cluster. About HA Monitoring On DEVICE | High Availability > Monitoring, you can configure both physical and logical interface monitoring: By enabling physical interface monitoring, you enable link detection for the designated HA interfaces. Sonicwall VPN solution provides our employees with secure access to internal and external data and resources. Enter the rank that Cluster Node 1 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. 8. Note that non-management traffic is ignored if it is sent to one of the monitoring IP addresses. Add the redundant port configuration (X2 as redundant port of X0, X3 as redundant port of X1). When the Enable Virtual MAC checkbox is selected on the High Availability> Advanced page, the SonicOS firmware automatically generates a Virtual MAC address for all interfaces. This specifies that Certificates, CRLs and associated settings (such as CRL auto-import URLs and OCSP settings) are synchronized between the Primary and Backup units. The following configuration parameters should appear with their correct values in the Tech Support Report: Responses, or actions, are always sent out from the active unit of the Stateful HA pair running Thus, Virtual Group 1 will include virtual IP addresses for X0, X1, and any other interfaces which are configured and assigned to a zone. The following table shows the licensing requirements for Active/Active Clustering and other High Availability features. Audio/Video Cables; Ethernet Cables; Network Cables 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. 13. Configuring Active/Active DPI Clustering High Availability. 7. On the active firewall of the Master node, go to the System > Diagnostics page and select Multi-Core Monitor to show the activity of all appliances in the Active/Active cluster. 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. If Stateful HA is enabled for the pair, the failover occurs without interruption to network connections. SonicWall SonicWave 621 Access Point; SonicWall SonicWave 641 Access Point .
