As Paul said, the better solution is to find some unused machine and
stick a pair of network cards/modem/DSL router/whatever into it and make
it the gateway/firewall. Build a Linux kernel (or use one from your
favorite distro) with either the ipchains (2.2 kernel) or
iptables/netfilter (2.4 kernel) stuff built in and use that as your
gateway/firewall.
A gateway, by definition (more or less) is the "one" computer that all
network traffic gets routed through. So you really can only have one
gateway. If both machines are "gateways" then really neither machine is
a "gateway" and both should just be called "hosts."
If you use one of the existing machines as your gateway, look into the
ipchains (2.2) or iptables (2.4) rules to make sure you block access to
that machine itself from the rest of the internet as well as to your
inside network.
