Yes, I have two interfaces on the Linux router. My setup is as you described: 
eth0 goes to the modem and eth1 goes to a hub for the client machines. I have 
a private IP network between eth0 and the modem and another between eth1 and 
the clients.

I don't think two interfaces on the router is a requirement, though. I think 
you can get away with only one interface, provided that all the client 
machines have the router listed as their gateway.
