Hello list

I solved the problem installing squid on the firewall and configuring it 
as a reverse proxy as described in 
http://squid.visolve.com/squid/reverseproxy.htm

The only line I had to add to my firewall script is in the INPUT chain 
allowing incoming connections on port 80 on the public interface.

Also, every www.xxx.unp.edu.ar on my external DNS server points to my 
firewall public IP.

Thanks everyone for your help
