IPS filter skype protocol detected wordt geblokt door de IPS maar deze moet doorgelaten worden. Extra info hieronder:

VoIP : Skype protocol detected 

Description 

Before the firmware version 9.1.0, the firewall detects the Skype Instant Messenger over the SSL connections in order to bypass classical security equipment. However, the latest Skype versions could not be detected (version 5.x.x).

 Starting from firmware version 9.1.0, the firewall is able to detect the Skype Instant Messenger over the TCP and UDP protocols on any virtual ports used including HTTP, SSL, and its custom protocol over TCP and UDP.

Details 

Starting from firmware version 8.0.0 the action and level associated with this alarm can be configured.

 For firmware versions before 9.1.0, if this alarm is configured as pass and if a packet that triggers the alarms is received, the corresponding plugin will detach from the connection and no further protocol analysis will be performed.

Starting from firmware version 9.1.0, there is a dedicated plugin for Skype custom protocol.

Triggering conditions Before firmware version 9.1.0, a Skype client attempted to initiate an SSL connection.

After firmware version 9.1.0, a Skype client attempted to initiate a HTTP/SSL/TCP/UDP connection.
