I am attempting to configure a route based vpn on a Sonicwall TZ device.
The datacenter has two public IPs on different subnets (A and B). The remote office has 1 public ip (C).
When I configure two tunnels from the datacenter firewall to the remote office (A to C as well as B to C), one of them always fails, most likely due to the same terminating IP address (C) at the remote site.
Sonicwall documentation states that this should be feasible but their tech support is unable to figure out how to get it to work.
Does anyone have experience configuring redundancy using sonicwall route based vpns?
