True -- do some research on Multi-NAT though.  I had it working fine on
that router -- and I would be extremely surprised if someone has not
implemented that technique under Linux.

Basically I was able to map multiple addresses (up to 255) and ports to
the 5 IP addresses I was assigned.  I don't remember for sure if you could
assign 2 different behind the firewall machines to the same NAT,
I didn't get THAT weird, but Multi-NAT is the concept you are looking for.

The router I have right now does single NAT, so I have to firewall the two
PC Anywhere machines independently.
