Are you trying to block by local port number? If yes, you will fail,

This is I don't understand? How can something be chosen randomly for every
program? Ftp should use port 21 and since that is not allowed out it's
blocked and that works. Perhaps I missunderstand you?

To clarify it all I'm using a Slackware 10.2 computer as a firewall and
connection to internet and some of the clients are Windows XP and it's on
the Slack comp. that I would like to block all connections from and to
microsoft messenger, this since it's a very good source to get viruses and
such things in to the computers.
