Usually, machines used as gateways have 2 NICs.  At least,
that's how I've always done it, but then I've had this DEC Tulip
PCI card for 7 years (and a 3c509 ISA card before that) for use
as the external interface.

Follow the IP-Masqing HOWTO for directions on how to do that on any
Linux box.  That doesn't cover setting up an iptables firewall on 
the external interface, though, and you *really want* to do that.

I had a separate firewall/gateway box for a while, and found that
it didn't add any value for my 2- or 3-machine home network where
99% of the time I was the only user.  YMMV, obviously--my desktop's
always running Linux so it can run whatever iptables rules would be
in a dedicated firewall box.
