Anthony,
For option 3, just block port 1863.
If you'd like to block certain MSN features, the following may be of
some help. (Note that if behind a NAT router these features will only
work if the NAT router is UPnP capable).
MSN's voice conversation port is 6901
MSN's file transfer ports are 6891 -> 6900 (inclusive) (MSN can handle a
maximum of 10 file simultaneous file transfers at a time).
Cheers,
Josh.

Hi,
The company I work for is having problems with people using MSN
Messenger
during the day, I have been asked to investigate ways to limit the use
of
MSN.
They would like to do one of the following things and I was wondering if
anyone has done anything like this or can point me in the right
direction.
-1 They would like to block MSN during the hours of 9am to 5pm.
-2 They would like to block MSN to certain IP Addresses
-3 They would like to block MSN completely
I would also like to know the port number that MSN uses if anyone knows
what
it is. Also I haven't really done anything with firewalls before so if
anyone knows of any good introductory tutorials then that would be
great.
We are running a RedHat 7.2 system as the server in the office with
windows
workstations.
Any suggestions would be greatly appreciated.
Kind Regards,
Anthony Irwin
