Hi there,
Could anyone advise me of the ports/destination that I would need to block
internal users from accessing MSN Messenger using a PIX firewall running
version 6.3 with access-lists.
I have looked on the web and it seems that it is port 1863 you need to block and the following range 64.4.13.0/24 of servers.
Could anyone confirm this please.

Hi -
Yes that's correct, use ACL's to block port 1863 and IP range 64.4.13.0 /24.
Hope this helps -
