Matt, all firewalls that I've had experience with work this way.  What you are in essence doing is "port mapping" on your firewall.  Internet users connect to your firewall, as if the firewall was the web server, the firewall then redirects that request inward to the appropriate machine which was mapped on your firewall.  The problems I've encountered though are when you have a server farm as you describe.
Let's say that the IP address of your firewall is 208.100.100.5, if someone wants to connect to a web server behind the firewall, they would actually be connecting to 208.100.100.5 on port 80.  But, you can only map 1 internal host to the external port 80.  Which means that you would either have to configure different ports for all of your web servers, or have one target server behind the firewall act as a redirector to all the other web servers.

Subject: Raptor 6.0 web traffic passing

I'm attempting to get Raptor 6.0 on Solaris to pass all web traffic
to any arbitrary host on the network behind the firewall (it's a web server farm).
It seems relatively simple to me: allow access to ports 80 and 443 globally. I have, however, been told that this is not the case by Raptor, and that there needs to be rules generated for each host intended to recieve web traffic. If I had 50 webservers operating in this environment, am I to believe that I need to make 50 config changes to accomodate them? Someone tell me this isn't so (or at least tell me that it is, so I can re-evaluate firewall technologies).
 
Matt
