Jabber Client

disallow access to a jabber server
Code: xmpp-client
iptables -A OUTPUT -p tcp --dport 5222 -j DROP

or using encrypted connection
Code: xmpps-client
iptables -A OUTPUT -p tcp --dport 5223 -j DROP

if do not want to block any ports at all you can use u32 module to inspect the payload of
the packets . refer to this site to learn more about examine the packets data
