anyone know what ports P99 uses

[swayz]

I have to have my college unblock some ports on their network and was wondering if anyone knows all the ports p99 uses. I had them unblock the login server port 5998 so I can get to the character select screen, but when i try to log the character in it says cant establish connection to the server. so there must still be some ports blocked. Any info would be much appreciated, thanks
