Question ID: 756861
I have a roommate that excessively downloads movies, music, programs,
etc... from LimeWire, Kazaa, and BitTorrent, etc... I would like to
block the ports that these programs utilize, so that my roommate can't
use these programs. I know how to block the ports, but I don't know
what ports these programs use. Could someone please tell me the port
numbers of these and any other P2P softwares?

Hi cmpaget,

I found the port numbers you asked for, and the most common P2P port
numbers, and listed resources below for you to be able to find port
numbers for anything(!) in the future:

Kazaa, Grokster, Morpheous 
TCP 1214
UDP 1214

TCP 4661-4672
UDP 4661-4672

WinMX & Napster
TCP 6257
UDP 6257
TCP 6699
UDP 6699

TCP 6881-6889
UDP 6881-6889

Gnutella (Bearshare, Limewire)
TCP 6346, 6347, 6348
UDP 6346, 6347, 6348

TCP 4444, 5555, 6666, 7777, 8888
UDP 4444, 5555, 6666, 7777, 8888

Share Direct
TCP 2705
UDP 2705

TCP 8038
UDP 8038

These are the most common P2P programs, however there's a fairly
extensive list of them at Wikipedia:

You can search for other PORT NUMBERS in a couple different ways:

For most P2P apps, you can change the default port to what ever the
hell you want, so your answer wouldn't really work...
