What ports does Skype TX require?

Outbound LAN>WAN (TCP/UDP) 443, 80

Inbound WAN>LAN (TCP/UDP) 443, 80

With the above rules the system will run in relay mode.


In order for the system to work optimally in UDP mode you need to add the following rule: -

Outbound LAN>WAN (TCP/UDP) 1025-65535

* Port 8000 to 8003 alone is not enough, you need also 34815 TCP and 18000 TCP to control SkypeTX from a different subnet with a firewall between.

* The computer name in windows and the name used on the company DNS must be the same otherwise the authentication from SkypeTX controller application fails.
