A user reported that his University uses Cyberoam firewall[0] and he can't
establish any Tor connections since then. So I gave him the PT bundle with
four working bridges one obfs2 and three obfs3, later he replied back with
a log that shows that the firewall blocked all the bridges[1]
isis said that it could be an sslmitm[2][3]. But according to sysrqb there
is no ssl handshake to mitm. so something else was used.
