Well, theoretically, IIS should be calling the ColdFusion kernel for processing support when it sees a .cfm page, so actually all your config should be in IIS on a port map, not in CF, since IIS will be the one receiving the requests.
Open your IISAdmin panel. Right click your site, and select Properties. Port number should be like the 2nd or 3rd input box down. I assume this site already has the DLL mapping or whatever to call ColdFusion for .cfm processing.
That should be it, unless maybe you're doing the IIS multiple-domain-hosting trick, where you go into the Site's advanced properties and tell it to listen for *.mydomain.com for this site (which allows you to host multiple domains on one ip address) -- I don't know how that will effect a port remap.
You should make sure you don't have other services competeing for the port, too, by downloading something like
scanport from
and port-scan yourself to see what's open -- set it to scan like ports 1 to 5000 and pick one that ain't being taken.
Hope that helps.
