Notice:
Remote Assistance TCP 3389 TCP/UDP 49152 65535
There is no way I would open a computer to remote access.
From the ports being used it appears Windows Live Messenger wants/needs the whole array of ports to fully work. Thats outragous!!!!!!
Windows Live Call TCP 443, 5061 UDP 5004 - 65525
That is like opening ever high port trojan port. You should be able to block all but four ports.
Okay, now we know why you are having this issue. The other services are trieing to call out.
In a business working enviorment this is not acceptable.
In the mean time CHAIN THAT DARN THING ! Use the above chart to block the ports you do not need and set Kerio not to log the blocks or alart you. |
