I have to connect two offices using 1841 routers . I just have an issue both the sides are behind a single subnet and I have to do NATTING. The issue is how will be the router able to manage that which IP exist at which site. The same issue exist with Remote VPN as well I have made a VPN pool with different IP and have add a route but the issue remains the same and i m still not been able to ping the IPs on the 2nd side
