    Blocking Skype with IPtables

    I really hate to post this , but some of you guys will probably need it one day.

    Block the hard coded nodes IPs for Skype : (this must be done on the gateway or the firewall)

    66.235.180.9
    66.235.181.9
    80.160.91.12
    80.161.91.25
    212.72.49.141
    212.72.49.142
    212.72.49.143
    195.215.8.141
    195.215.8.145
    64.246.49.61
    64.246.49.60
    64.246.48.23

    I used iptables to block them from my linux gateway:

    iptables -A FORWARD -p udp -i eth1 -d 66.235.180.9 -j DROP
    .........
    .....
    ....
    iptables -A FORWARD -p udp -i eth1 -d 64.246.48.23 -j DROP

    that was to UDP packets , repeat the same for TCP :
