Custom routes? When routing between 2 networks using the same range, either with a VPN or some kind of direct connection? It's going to need some evil double NAT sorcery, especially if the same actual addresses are in use on both.As long as: a) It's L3 VPN, so ARP is not a concern. b) There are no duplicate IPs on both sites combined. The problem can be 'solved' by announcing specific IP routes to each and every host on both sites. Yes, it's gross.
Not all hosts accept route announcements (using which protocol ?). You may have better luck with ARP proxying on the routers (yet another kludge).
