Enabling port forwarding
We know that we need to forward port
9001
, as it is the ORPort, but we need to know
which port the obfsproxy software runs on. This will be logged in the same file and will be
discovered by searching the Tor log with the following command:
grep obfs3 /var/log/tor/notices.log
The previous command should yield the following search result:
Mar 05 01:56:04.000 [notice] Registered server transport
'obfs3' at '0.0.0.0:59519'
The
obfsproxy
port for our obfs3 service is on
59519
. From your home router, config-
ure port forwarding from
9001
, and configure port forwarding from
59519
from your ex-
ternal IP to BBB. It will also help if you give your BBB a static internal IP. Consult your
router's manual for directions. Alternatively, you can specify the port with the following
line in the
/etc/tor/torrc
file:
ServerTransportListenAddr obfs3 0.0.0.0:xxxx
Replace the x's with the desired port address. However, it's best to let obfsproxy pick a ran-
dom address; otherwise, the Tor Project might end up with an uneven distribution of
bridges running on certain ports, which will make it easier to block access to bridges.
Once you've forwarded the necessary ports, restart the router again. You should see the fol-
lowing messages, indicating success:
Mar 25 21:37:43.000 [notice] Now checking whether ORPort
xxx.xxx.xxx.xxx:9001 is reachable... (this may take up to 20
minutes -- look for log messages indicating success)
Mar 25 21:37:44.000 [notice] Self-testing indicates your
ORPort is reachable from the outside. Excellent. Publishing
server descriptor.
Congratulations! You are now running a Tor bridge on BBB and are helping to improve In-
ternet freedom. You are also enabling agents, both secret and otherwise, to access the un-
filtered Internet.
