The following command will block access to AOL from all client workstations
connected to the server:
/sbin/iptables -t nat -I PREROUTING -p tcp -s 192.168.0.0/24 --destination-port 5190
-j DROP
Make sure that your source address (the "-s" option) is correct for your
network.

What's real successful for us is ingress/egress filtering; not blocking
bunches of certain ports but rather defining which ports traffic can
flow outward from, and assuming that your firewall denies all
unsolicited inbound traffic by default.
for instance - I have 3 ip addresses accessing the
Actually, that worked! Thanks juaid!
