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.
