That's kind of what I was thinking. It should be possible to set the default route, to work through the cablemodem router, and set only what ever private class C is desired, over the other card, and only that class C. Then, run Samba, listening only to the class C interface, and all other services listening to all interfaces, but only originating connections on the cable modem router interface. There are ways to forse all of this with iptables, but I would personally consider that a cluge. > Of course, unless you really needed your machines to use different internet > connections, you could just have your linux machine connected to the net If you run a big network, with many machines, and more than one server, his setup actually does make some sense. The windows segments use one highspeed conection, with their services, and the Linux side uses its highspeed connection, with its services. Depending upon your available connection speeds, this can be understood as valuable, although with a slight dubious factor.

Note: when dealing with always-on connections, it qualifies as NAT. masquerading applies only to temporary (usually dialup) PPP connections. Luke
