hello,
msn is using multiple ports, is it possible to block msn messenger?
Are you using webproxy?
If yes you can block by url:
webmessenger.msn.com
loginnet.passport.com
MSN uses port 1863, you can setup a rule to block dst and src 1863
No, you won’t be able to block MSN Live Messenger. Whatever port you block, it will try to a different one untill it connects.
Try to block port 5050, It will work
Live messenger try to connect using the 1863 port first, if it can´t, then try with anothers…
My solution to block Live messenger is :
/ip firewall filter add chain=forward action=drop src-address-list=30segBlock
/ip firewall filter add chain=chain=forward action=add-src-to-address-list protocol=tcp address-list=30segBlock address-list-timeout=30s dst-port=1863
When it try to conect, i block the source IP for 30seg to avoid trying with another ports.
This is not the best solution, but work for my.
