[Edit] Is it possible to use a port number instead of a sub-domain?

[bpat1434]

I'm installing this on my local test server so to get to it I type in the IP address instead of a fully qualified domain. Now, have a DynDNS account; however, I can't use it from this side of my Linksys router (since it would just activate the loopback and bring me to the router admin interface).

So my question is this: Is it possible to use a port number instead of a sub-domain? Just like cPanel or Plesk or webmin?

If it's possible, what files would I have to edit before I do the "make install" command? I'm fairly linux literate; however, I'm not sure of the coding you guys did. So if it's possible, I'd like to know how so I can test this out.

By the way, I'm using CentOS 5.1.
