> What is the address of the subnet "other LAN" ? > There seem to be two more subnets, 192.168.180.0 and 172.17.0.0. You are right, both of them are accessible through eth3 and the same box of 192.168.180.100 (I didn't include the whole routing table) like: 172.17.0.0 192.168.180.100 255.255.0.0 UG 0 0 0 eth3 192.168.0.0 192.168.180.100 255.255.0.0 UG 0 0 0 eth3.
