Hello, how can we block the use of the msn messenger with iptables?
ive tried blocking dport 1863, but the client tries then port 80 , port
443, and i cannot block those ports.
Then ive blocked some networks of M$ but i had to remove the rules
because some people uses hotmail.
Any help? (i think that packet inspection could see if the packet to
port 80 is a GET/POST or a different packet to mark.... but how can i do
this????)
any help??
Thanks in advance and best regards

Is the MSN packets TOS field different then a regular web surfing packets ?
If so you could block it by the TOS field.
