Is there a way to change the port that Web Publshing Engine listens to as it serves a FM database?

Network/server issues internally here have forced me to install the Web Publishing Engine and FM Web Server modules on a different machine than the FM datbase (FM Server 8.0v4). I have an XServe that is hosting FM Server.

The issue i'm facing now is that i need to port-forward incoming web traffic to the box running WPE. The default WPE port is 80. But i have a web server running on the XServe which also is looking for web traffic on port 80. If I could change the port that WPE listens to (591 for instance), I could configure my router to forward traffic for 591 to that box, and keep web traffic coming to port 80 on the Xserve. I unfortunately don't have the option in my router to translate traffic from one port to another.

If this mess is not explained properly, all I need to know is the answer to my first question and I'll take it from there.

Thanks

The port is set in either IIS or Apache since that is where the web serving is being performed. You possibly could establish more than one web site in Apache? I know this can be done in IIS.
