Ugh. This sucks.
What do you mean by "unknown port"? Which ports do they allow?
Not sure yet. Mostly like they've whitelisted the known protocols. I didn't have a chance to login to my box yet :/
I see.
It would be interesting to learn which ports they currently whitelist, except from the usual HTTP/HTTPS.
I also wonder if they just block based on TCP port, or whether they also have DPI heuristics.
On the Tor side, it seems like we should start looking into #7875: https://trac.torproject.org/projects/tor/ticket/7875
