Block Microsoft messenger on Speedtouch router

Blocking tcp traffic from two ranges of IP addresses on ports 80 and 1863 prevents MSN messengerlogin and initialisation.

You can input the following via telnet login to your speedtouch (telnet -l <user> 10.0.0.138) for temporary use—to revert to saved configuration use system reboot, save or add it to the firewall section of user.ini for a permanent block. (View source to see lines split here.)

firewall chain create chain=nomsn

firewall rule create chain=nomsn prot=tcp srcport=1863 src=65.52.0.0/14 action=drop
firewall rule create chain=nomsn prot=tcp srcport=1863 src=207.46.0.0/16 action=drop

firewall rule create chain=nomsn prot=tcp srcport=80 src=65.52.0.0/14 action=drop
firewall rule create chain=nomsn prot=tcp srcport=80 src=207.46.0.0/16 action=drop
