Sorry my explanation was lame. Each of these Remote A, Remote B, and Remote C are separate networks in different and remote locations. B only has one ethernet card because the ISP has a router with nat translation directed to its ethernet card. ie the IP address of B is 10.0.0.x internally and the router translates the external 64.70.99.20 to 10.0.0.x. Remote A and Remote C have two internet cards each. One card is connected to the internet and the other card is connected to the local lan at each site. With A and C all traffic is required to go through them to reach the internet. With B I route all traffic through it, but the traffic is not required to go through it. Each of these networks has a different isp, and their own gateway ie (A, B, and C). I am getting ready to change isp on B and when that happens it will become a two ethernet card machine as well but before I switch I would like to be able to get cups to work behind a two ethernet card system. I use a subnet on the local network behind A, B, and C of 10.0.0.*. In essence I can easily get cups to work on a subnet behind a gateway that functions with the same subnet (B), but I can not get cups to work on a subnet on the inside of a gateway that has an external ip on a different subnet than the interal lan (A and C). Sure appreciate your help!!! Greg
