Same thing. they target both TCP and UDP packets.

I'd love to know this, but so far I haven't had a chance to get my hands
on that network.

We might be able to do something creative tho!
More than 30 ppl have sent queries to Tor Farsi help desk. Most of them
are willing to help.
Maybe we should write a very tiny small program, which will run few
tests and write results in a log file. So we can give it to our
volunteers inside Iran to run it and send us the result.

Maybe OONI ppl can help with that?
