I've been up way too long, and got a project tossed into my pile of work. For the life of me I can't seem to get this routed right. Here's the situation we have a server at one site, and another server at the other site. Both have networks currently communicating over Site 2 Site VPN, I need to get an alternat subnet IP at each location to route to one another. Site A: 10.10.X.X Site B: 172.1.1.X Server at Site A: NIC one = 10.10.0.100/16 ; NIC two 10.240.10.10/16 Server at Site B: NIC one = 172.1.1.100/24 ; NIC two 10.241.10.11/16 Via the Site2Site VPN from A to B traffic sources each network fine, but I'm at a loss right now on how to route the other subnets for the alternat NIC. IE: 10.240.10.10 can deliver packets to 10.241.10.11 and vice versa. Anyone able to jog my brain along in getting this sorted out? Do I need to create a virtual gateway on the firewall/router at each site IE: 10.240.10.1 in site A & 10.241.10.1 in site B under the main inside interface? The short and sweet of it is, we have a DR product that assists with failover and it has a heartbeat interface configured at both sites that need to talk to one another autonomous of the primary interface on each server. Appreciate any help you might be able to give. Thanks, Kel

Thanks. We'll let you know when a new response is added.

May wanna look at the routing to ensure whatever protocol you’re using knows about ALL of the subnets, so it knows where to send the traffic…
