Howdy, im looking for the port numbers on which Windows Messenger live runs on by default, - im looking to place a block in my router during certain hours of the day! certain pesky kids that I know are not doing their homework when they are supposed to.....

Copped directly from an add for some messenger blocking software:
Windows Live Messenger is an updated version of MSN Messenger and uses similar ports. As part of a forum to Microsoft's web site and other web sites (e.g. www.cyberphaze.net - not currently online) it seems that Windows Live Messenger uses:

Messenger server: port 1493, 1542, 1863, 1963, 80 TCP and 443 TCP
File Transfer/Sharing Folders: local: 1544 and 6891 - in fact 6720-65535 TCP from one source
Messenger Update: remote: 80 local: 1457
Remote Assistance If available): 3389 TCP
Audio: local: , 1556, 11771, 13803 and generally 5004-65535 UDP
Remote Desktop and whiteboard: local/remote: 389, 522, 1503, 1720, and 1731
Launching Games: 80
Video Conference: TCP 9000-9999, 5004-65535 UDP + 80
Sign-In: remote: 443 local: 1484, 2400

Note - blocking TCP port 80 will stop users accessing web sites using Internet Explorer and other browsers.


Nuking the sign in ports would probably do it.
