[CentOS] DROP MSN MESSENGER by IPTABLES- CENTOS 4

[Rafael Azenha Aquini]

It's more simple deny the messenger's port. try the follow rule:

/sbin/iptables -t filter -A FORWARD -p tcp --dport 1863:1864 -j DROP

by this way, the client is disabled for auth process in MSN servers, and
you can say bye-bye to this cancer... :-)
