After a failover to the Backup appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. The failover applies to loss of functionality or network-layer connectivity on the Primary SonicWall.
You'd have to make sure that the remote side VPN tunnel has both the primary WAN IP or DNS name and the secondary LTE IP or DNS name. If it loses connectivity to the primary IP it will attempt to connect to the VPN using the secondary IP. You should also be able to have it fall back to the primary once it comes back up. level 1 Idk, I never got 4g sticks to work, we used a cradlepoint instead on the sonicwall. It worked actually pretty good, however for those we did use it, they have no VPN, just a failover line for regular internet. I assume in the worst case that the VPN drops on failover, in the best it'll be fine. Probe responder.global.sonicwall.com on all interfaces in this group —Enable this checkbox to automatically set Logical/Probe Monitoring on all interfaces in the Group. . When enabled, this sends TCP probe packets to the global SNWL host that responds to SNWL TCP packets, responder.global.sonicwall.com, using a target probe destination address of 204.212.170.23:500 The VPN Policy window is displayed , Click the Advanced tab . Select the VPN bound to option. Select Interface X2 (3.3.3.3) as the Primary gateway as Site B is set as the same IP – 3.3.3.3. NOTE: By default, VPN policy bound to option is set to zone WAN where VPN tunnel will be established with Primary WAN as configured in Failover/Load balancing . For a SonicWALL appliance with a WWAN interface, such as a TZ 190, you can configure failover using the WWAN interface. Failover between the Ethernet WAN (the WAN port, OPT port, or both) and the WWAN is supported through the WAN Connection Model setting.

I have a need to setup a failover VPN. I have two sites that each connect to the same remote site via a site-to-site VPN. The remote site has installed a failover internet connection and would like me to configure a failover VPN on my two sites. So my two sites are a Cisco ASA 5505 and a SonicWALL TZ200 Wireless. Each connection is counted against the maximum number of tunnels for your Azure VPN gateway, 10 for Basic and Standard SKUs, and 30 for HighPerformance SKU. In this configuration, the Azure VPN gateway is still in active-standby mode, so the same failover behavior and brief interruption will still happen as described above. But this setup
Jul 10, 2015 · In this guest post, our customers Kelley Parkes, Director of Technical Operations (on the right) and Dave Rupert, Systems Engineer (on the left) at First Source, describes how their company built a site-to-site VPN with SonicWall NSAs and TZs to enable secure collaboration and failover protection to sites spread across the country.
Microsoft Azure and SonicWALL STS - Part 2 – Configure SonicWALL OS VPN policy. Microsoft Azure and SonicWALL STS - Part 3 – Configure VPN policies and Routing. Extending the on-premises infrastructure to Azure, the obligatory need is to create site-to-site VPN to access resources in both side. Dead Peer Detection (page 6 of 6) of the IPSec VPN configuration) determines failover/failback time The default failover time is 115 seconds (Connection Idle Time + (Request Period x Maximum Request)) The default failback time is 10 seconds (Failback Retry Period) 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. The configuration tasks on the High Availability > Monitoring page are performed on the Primary unit and then are automatically synchronized to the Secondary. After a failover to the Backup appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. The failover applies to loss of functionality or network-layer connectivity on the Primary SonicWall. When using multiple WANs, a primary and secondary VPN can be configured to allow seamless, automatic failover and failback of all VPN sessions. Route-based VPN The ability to perform dynamic routing over VPN links ensures continuous uptime in the event of a temporary VPN tunnel failure, by seamlessly re-routing traffic between endpoints through Dec 11, 2019 · Configure a Site-to-Site VPN as a failover path for ExpressRoute. You can configure a Site-to-Site VPN connection as a backup for ExpressRoute. This connection applies only to virtual networks linked to the Azure private peering path. There is no VPN-based failover solution for services accessible through Azure Microsoft peering. Also, are you having one or two VPNs with failover? Since you are seeing the packets being consumed, just check the statistics on the SA itself and see if the transmitted packets are bytes are increasing. If yes, then the SonicWall is forwarding the traffic correctly.
