I tried to install WinMX 3.54 beta on my Windows XP computer and it needs me to map a port other than 6699 to receive incomming TCP connections. I have a linksys wired/wireless router. I have no clue how to do this. Can anyone help?

Look through there. Other than that you get much help here with P2P apps.
