We are currently using a 3015 VPN concentrator on which we support access to two separate client subnets. I can't use a default tunnel gateway because I have two separate networks. I dont have a router behind the VPN box. I can ping a network that I have a LAN-to-LAN tunnel setup with from the client network but not from the other end. It seems as though the destination network doesn't know where to route ICMP replies back to. How can I route client traffic to the appropriate network? I already have static routes in the concentrator but they don't seemt to work for this LAN-to-LAN tunnel.
