Hi
I've set up a standard site to site VPN between 2 ASA 5505s (using the wizard in ASDM) and have the VPN working fine for traffic between Site A and Site B on the directly connected LANs.
But this VPN is actually to be used for data originating on LAN subnets that are one hop away from the directly connected LANs. So actually there is another router connected to each ASA (LAN side) that then route to two completely different LAN ranges, where the clients and servers reside.
At the moment, any traffic that gets to the ASA that has not originated from the directly connected LAN gets sent straight to the default gateway, and not through the VPN.
I've tried adding the additional subnets to the "Protected Networks" on the VPN, but that has no effect. I have also tried adding a static route to each ASA trying to point the traffic to the other side, but again this hasn't worked.
Here is the config for one of the sites. This works for traffic to/from the 192.168.144.x subnets perfectly. What I need is to be able to route traffic from 10.1.0.0/24 to 10.2.0.0/24 for example.
ASA Version 8.0(3)
