you can do this a few ways:
a) put your web server "on the outside" of your firewall, creating a DMZ
b) you want to set up a rule that forwards the incoming port 80 requests to
the appropriate internal server and back again.. assuming the external IP
address was 1.2.3.4 and your web server was on 192.168.1.2 something like:
iptables -t nat -I PREROUTING -p tcp -d 1.2.3.4 --dport 80 -j DNAT
- --to-destination 192.168.1.2:80
c) if you need anything more complex, you'll need a more complex solution such
as the load balancing services of Linux Virtual Server (LVS)
