With a site-to-site tunnel on two ASA 55xx boxes, do both ends of the tunnel need to be on the same IP subnet? Or will the tunnel terminate "before" the routing function so my two subnets can talk?
eg: (in the following, the "<###>" is the tunnel)
so, my two LANs 192.168.7.x and 192.168.50.x have the ASA as their default gateway out (the ASA's have an interface using the "...1" address on that subnet). And the 10.x.x.x and 172.x.x.x networks are just the outside interfaces on the ASAs with the tunnel between them.
My question is: will 192.168.7.x be able to talk to 192.168.50.x? (eg: will the ASAs perform the routing function between the two subnets?)
