If you want to can also use the crossover cable solution and route the
traffic destined for the other machine over the directly connected
interface. (I do something like this when I use my FC 4 box as a firewall
for Windows boxes. I have modifed ifup-eth so that I can easily use the
same IP address for outgoing packets on multiple interfaces using the
"peer" argument to ip.)
Using a different subnet is probably better in this case since both machines
have their own external connection, but if having multiple IP addresses is a
problem using a point to point connection better.
