multiple webservers behind iptables

["Raul I. Becette" <raulbecette@unp.edu.ar>]

Hello list

This is my first post.
I am in charge of a LAN connected to internet through a firewall box 
PIII 500MHz with iptables 1.2.10.

There are different internal webservers that I don't adminnister and are 
located physically in different parts of the building.
There is an internal DNS server which I administer to resolve internal 
www queries.

My problem is that from the outside I cannot access those webservers 
when I type www.xxx.unp.edu.ar (xxx being the name of the server).
My net schema is the following


                                     INTERNET
Mail Relay            Main Web Server             Router


-------------------------Firewall--------------------------------


POP Server         Proxy         Webserver1      Webserver2
                                         LAN

My question is how can I use iptables rules to be able to access those 
servers from the outside.

Any info you need just ask

Thank you for your time
