New infos for Skype detection with MWG7 proxy?


I wonder if there are new infos concerning  Skype detection in a MWG7 proxy based internet connection.

We need a solution for allowing  Skype through MWG (V7.2.0.8)  proxy   for some users.

Because Skype has some typical network behaviour even in proxy environment and

since most network based (NG-) firewalls can detect skype traffic I think it should be possible to solve this.

In the moment we use a very simple SSL-Scanner ruleset part for Skype separation:


Membership of group PowerUsers comes from  NTLM authentication.

Of course, this disables SSL scanning for more than just Skype connections.

Is there a better solution?

Best regards,

Michael Ardes

Hi Michael,

Making the assertion that any request made by IP address is skype is not a good idea. This is especially true in transparent setups.

In the past I have posted about this previously, but the cleanest way to know if a request is coming from skype is to direct it to a separate proxy port.

Here is an example ruleset I have offered:

As far as detecting the traffic, at the moment MWG cannot differentiate between skype SSL and normal SSL. Skype SSL is a broken version of normal SSL (from what I understand).
