Hi, Use proxy server like squid - it's easyer than using just a firewall like iptables.
with a proxy server you can build a acls to block users, ip address, urls, etc... with a firewall server you can build acls to block ip address, ports, etc... but it's more difficult to block users. another approach is to block ms-messenger to be executed by users - you can use ms approach (policies), you can use personal firewalls or any other applications that blocks applications to be executed.
