Block Skype by p2p filter module in Active Wall

[admin]

Another way to block skype, please read Blocking Skype with Active Wall Professional.

Skype will readily leak out of the network, using high-numbered ports—either TCP or UDP. As a last resort, it will use ports 80 and 443, which are most commonly used for Web traffic.

3. Https Filter Config
The Skype client can pass through tcp 443 port by using TLS protocol.
So we should check [Disable TLS 1.0] option, or we can check [Deny https proxy tunnel] and [Deny server without certificate] options.
