I may not have understood the question,
but I would use two different subnets, say 192.168.1.* and 192.168.2.*
for the two connections.

If you are not using dhcp you can do this by specifying the IP addresses
in /etc/sysconfig/network-scripts/ifcfg-[ath0,eth0] .

I think many people have two (or more) connections active 
on the same computer.
