Re: IP2P & Skype question

[Justin Schoeman <justin@xxxxxxxxxxxxxxx>]

I don't think Skype works very well with any of these.  I have tried the 
l7-filter pattern, with no luck.

Apparently, the big problem is that Skype traffic is encrypted, and so 
it is not possible to match it using fixed patterns.

In some cases, it is possible to block Skype, as the existing pattern 
seems to match an important, but not yet encrypted packet.  Shaping is 
however not possible, as the matched packet makes up very little of the 
traffic.
