i have a situation with 2 overlapping networks that need to communicate using a 1720 with one ethernet interface e0 192.9.200.18 255.255.255.240 the station that needs to join the network is 192.9.200.30 255.255.255.0 which is already in use on another router interface that is part of the network. There is a station that needs to send to .30 over the WAN with the address of 192.9.200.2 255.255.255.0, none of these addresses can be changed yet. Is there a solution for this mess. Any help would be appreciated.
