Easy way: The dialout machine (the one that has the modem in it already and you're dialing up to the internet with) would be the firewall and IP masquerading server. It plugs into the switching hub, as do the rest. Regular CAT5 - nothing special. The other two machines just plug into the switching hub as well. Set the "dial out" machine to 192.168.0.1, and the other two machines to the same static IP structure - i.e., 192.168.0.20, 192.168.0.30 (or whatever you desire). After you've confirmed that the three can "talk" or see each other well, start working on your firewall. Without knowing what setup you're using for the firewall (ipchains or iptables) - the software you're using should have some place to setup the IP masquerading - forwarding ppp0 calls over eth0 - I personally don't like using "third party programs", but do the scripts manually along with setting up the IP masquerading manually. It's a relatively easy setup, but I do remember when I was first doing it, it sucked, and it appeared quite more complex than what it really is.
