[tor-talk] Tor bridge with no traffic

Hi,

I'm running a Tor bridge for some days now (after shutting down an exit 
node, due to too many DMCA complaints) but it's hardly getting any 
traffic:

  Heartbeat: Tor's uptime is 1 day 11:59 hours, with 2 circuits open.
  I've sent 7.34 MB and received 24.86 MB.

I feel like it's configured wrongly, though the log file does not report 
any errors:

Tor 0.2.3.12-alpha-dev (git-81fe3e438b39cd14) opening log file.
No AES engine found; using AES_* functions.
This version of OpenSSL has a slow implementation of counter mode; not using it.
OpenSSL OpenSSL 0.9.8o 01 Jun 2010 looks like version 0.9.8m or later; I will try SSL_OP to enable renegotiation
Your Tor server's identity key fingerprint is xxxx
Configured hibernation. This interval begins at 2012-02-21 00:00:00 and ends at 2012-02-22 00:00:00. We have no prior estimate for bandwidth, so we will start out awake and hibernate when we exhaust our quota.
Parsing GEOIP file /opt/tor/share/tor/geoip.
Configured to measure statistics. Look for the *-stats files that will first be written to the data directory in 24 hours from now.
This version of Tor (0.2.3.12-alpha-dev) is newer than any recommended version, according to the directory authorities. Recommended versions are: 0.2.1.32,0.2.2.35,0.2.3.10-alpha,0.2.3.11-alpha,0.2.3.12-alpha
Reloaded microdescriptor cache.  Found 2910 descriptors.
We now have enough directory information to build circuits.
Bootstrapped 80%: Connecting to the Tor network.Heartbeat: Tor's uptime is 
0:00 hours, with 4 circuits open. I've sent 0 kB and received 0 kB.
Bootstrapped 85%: Finishing handshake with first hop.
Bootstrapped 90%: Establishing a Tor circuit.
Guessed our IP address as x.x.x.x (source: x.x.x.x).
Tor has successfully opened a circuit. Looks like client functionality is working. Bootstrapped 100%: Done.
Now checking whether ORPort x.x.x.x:9001 is reachable... (this may take up to 20 minutes -- look for log messages indicating success)
Self-testing indicates your ORPort is reachable from the outside. Excellent. Publishing server descriptor.
Performing bandwidth self-test...done.

I've forwarded port 9001/tcp from the internet-facing router to the 
machine where tor is running, of course.

My torrc looks like this:

I've also installed a bridge in an Amazon EC2 with the TorCloud project 
and here I have the same problem:

  Heartbeat: Tor's uptime is 23:59 hours, with 0 circuits open.
  I've sent 2.44 MB and received 13.41 MB.

Network-wise things seem to look fine:

  Feb 21 20:42:17.000 [notice] Self-testing indicates your ORPort is 
  reachable from the outside. Excellent. Publishing server descriptor.

The torrc for the EC2 bridge:

-------

SocksPort 0
ORPort 9001
ORListenAddress 0.0.0.0:9001
BridgeRelay 1

Any ideas on how to get the bridge going?

Thanks,
Christian.
