I am trying to set up a test environment where two IP segments attached to the same router (running IOS 12.0(7)) will not forward traffic between them directly. I want the IP traffic from Segment A to be routed out a third interface (a WAN interface) and then get routed back to Segment B after crossing my WAN cloud.
To do this, I somehow need to disable local routing between the two directly attached segments. Any ideas how I do this?
Once I get this far (assuming I can) the WAN network will be a further issue but the first step is to bypass the local routing.
Any ideas welcome. I can't see the forest for the trees maybe.
Thanks, P
