Port Issues

[.=QUACK=.Major.Pain]

I have used ports for servers in the past like 2310, 2315, 2320, etc.
The servers no longer exist and I assume these ports are now freed up.

But when I create a new server, using say port 2320, and same ip as the old server used, when the console opens up, it uses port 2314 instead.

Is there something that additionally needs to be done to free up these old unused ports?

Ah shoot. Nevermind.
My mistake.

Had -port-2320 and finally saw I had a '-' instead of a '='
