---------------------------------+---------------------
 I'm currently in Istanbul, Turkey at a local university. The network
 blocks connections to the Tor network (using Tails) with a layered
 approach to censorship, I suspect.

 I've tried to configure regular bridges, obfs2,3,scramblesuit PT and
 direct connections. None appear to function. I am able to ssh out - so I
 can connect to Tor by binding a local SOCKS proxy and configuring Tor to
 connect over a SOCKS proxy. That is how I've filed this bug report.

 The Cyberoam device is clearly acting as a MITM - it is highly annoying.
 It is a captive portal, which is easy to bypass with a login/password
 (ironically, not deployed with https!), after the captive portal, it
 filters conections by protocol, ip address and port number - I haven't yet
 fingerprinted the device upstream but I'll add information as I find it.
