Hamlesh, sounds like you want a NAT'ed LAN on eth0 and a non-NAT'ed DMZ 
on eth1. A firewall with two zone, LAN and DMZ, is a pretty common 
setup. You might want to take a look at Shorewall 
(http://www.shorewall.net/index.htm) and in particularly the three 
interface Quickstart guide, which will lead you through setting up a 
firewall of the type you need.
