Server install Q - interfere with existing services?

Hi all,

I put together a test server, and all went well. I would like to run Openfire on a production server, and am curious if it might interfere with any existing services.

The server is a linux Fedora 7 box, running two intranet webpages (apache) and also functions as a squid box.

It also has three network cards (and 3 IPs) - will Openfire respond to any incoming request on these IPs? Or do I have to setup 1 in particular?
