Cross-posting to tor-relays to give everyone the heads up - I just added 33033 to the ReducedExitPolicy page for Skype: https://trac.torproject.org/projects/tor/wiki/doc/ReducedExitPolicy Non-relay related discussion should remove tor-relays from the Cc. James Brown:

Hello, people!

Because many my contacts continue to use Skype and don't want to use any nice soft (such as jabber, torchat and etc.) I need to use it too. For protecting of my location and etc. I use it only through Tor (on VM working under transparently-torifed user). Some days ago I would be very, very difficalt to connect to skype through the Tor-net (earlier it was very easy). As can I see in my Vidalia, my skype application can make resolving through tor and can connect to hosts through port 443, but conncetions with port 33033 cannot establish (I can the the trying to open it and after it it closed immediatly). As can I see the skype doesn't work without that connections which now establishes very rarely. I have 2 versions: a) the Skype team ban the Tor-connections to skype (but I can still connect to skype to ports 443 and I can to browse their web-site and even log in to it through the Tor without any problems) or b) many Tor-exits don't let the above-mentioned port (33033) in their ExitPolicy.

It is not good from the Skype team if they do the first. If the second hypothesis is right I ask owners of Exit-nodes, if it possible, to let that port in their ExitPolicies.

Not sure if that's actually the problem, but if the only way you can get to Skype is to use a Bittorrent-supporting exit, it certainly seems like a possibility. Thanks for the heads up James! -- Mike Perry
