huh?  Try using the firewall on the squid box to forward incoming
traffic for port 80 to the squid port.  Unless you are running squid at
port 80--which is possible I suppose.

If you are trying to automatically forward port 443 (ssl) i don't think
that will work.  ssl traffic will need to use the proxy setup in the
browser.

If I understand what you are trying to do it involves more than just
squid to do it.  Probably need to re-direct all port 80 traffic that is
not from the squid box to the squid box on the real firewall.  Then
allow squid box to access port 80 through the firewall.

Is the proxy server (squid) the same as the firewall?  same principles
apply just on one machine rather than over the network.
