[tor-talk] Cannot get through restrictive firewall

[Lorenzo Milesi]

Hi.
I'm trying to connect to Tor in a restricted network but I'm failing.

I added these options to my torrc from the results I found searching:
ReachableAddresses accept *:443
UseBridges 1
Bridge obfs3 1.2.3.4:443 key1
Bridge obfs3 5.6.7.8:443 key2

but when restarting the daemon it remains stuck at 10% "Finishing handshake with directory server".
I also tried removing the transport and the key but same result. 
I'm using Tor version 0.2.6.2-alpha (git-d9181ab02241e41f) on Ubuntu.
I'm not aware of any proxy needed, I don't need any when browsing normally.

Anything else to check?
thanks
