today we experienced problems with skype. We could see our Branch Office web cam, but people at Branch Office could not see us. The quality of internet connection detected by sky was poor (but we have 4mbit fiber and at that time the used bandwidth was poor). Consider that 1 hour before this issues all worked fine. I found no entries in IM/P2P and we do not scan https traffic. I have only seen a lot of blocked packets between our LAN and Branch Office public wan address:

But I think that it should not be a problem because skype is set to use also https and http protocols. What is going wrong?
thank you
