    sure !!! Pretty simple.

    you'll need a DNAT rule for the 80 port forwarding

    and you'll need a SNAT rule to, to make the firewall source-nat all 
connections 'going' to your real webserver

192.168.1.1 = your firewall
192.168.1.200 = your real web server


iptables -t nat -A POSTROUTING -p tcp --dport 80 -d 192.168.1.200 -j 
SNAT --to-source 192.168.1.1
