Hey gang-

Ive got a network card, and one IP on it using gSheild as my firewall.

Ive got a dozen (could be a hunderd or two in the future) other IP's 
that i want to be routable (they are all public ip's).

I want to continue to use gShield.  

 A friend once mentioned putting all the other IP's on the loopback IF. 
This made all the other IP's world routable, and all the firewalling was 
done on the eth0.
Does any of this make sense? IF not, what is the best way to get lots of 
IP's on a single NIC, with easy firewalling?
