Blocco di MSN Messenger sul firewall

Per bloccare MSN messenger occorre bloccare in toto l'accesso alla rete 207.46.110.0/24. 

iptables -A FORWARD -i eth0 -o eth2 -m state --state NEW -p tcp  -d 207.46.110.0/24  -j REJECT
iptables -A FORWARD -i eth0 -o eth2 -m state --state NEW -p tcp --dport 1863   -j REJECT

Oltre al firewall, occorre anche bloccare l'accesso in squid: 

acl msn_messenger dst 207.46.110.0/255.255.255.0
acl msn_header_req    req_mime_type  application/x-msn-messenger
acl msn_header_rep    rep_mime_type  application/x-msn-messenger

http_access deny msn_messenger
http_access deny msn_header_req
http_reply_access deny msn_header_rep
