Hi Vaibhav,

To block Msn messenger with iptables.

# iptables -A FORWARD -p tcp --dport 1863 -j DROP

To block Yahoo messenger --> this might work but not sure..in my case it worked before 9 months. Yahoo messenger works on different ports. you can offcourse restrict the whole domain but that would not be fair.

# iptables -A FORWARD -p TCP --dport 5000:5010 -j REJECT # iptables -A FORWARD -d cs.yahoo.com -j REJECT # iptables -A FORWARD -d scsa.yahoo.com -j REJECT
