It sounds like you need to setup your internal machines to use you router machine (the one with 2 NICs) as their gateway. If your internal machines are Linux, you can type: # route add default gw router_machine_name This only works if there's already a route in the route table to router_machine_name (sounds like there is from your description). If they're Windows, you can put the gateway IP in the network setup somewhere. Matthew
