Hi everyone,
BridgeDB is running low on obfs4 bridges and often fails to provide users with three bridges per request. Besides, we recently fixed a BridgeDB issue that could get an obfs4 bridge blocked because of its vanilla bridge descriptor: https://bugs.torproject.org/28655
We therefore want to encourage volunteers to set up new obfs4 bridges to help censored users. Over the last few weeks, we have been improving our obfs4 setup guide which walks you through the process: https://trac.torproject.org/projects/tor/wiki/doc/PluggableTransports/obfs4proxy
The guide provides instructions for Debian, Ubuntu, CentOS, RHEL, OpenSUSE, FreeBSD, and OpenBSD. If you're running into any issues with the guide, please let us know!
Finally, once you set up an obfs4 bridge, make sure that both your ORPort *and* your obfs4 port are reachable. Tor currently only tests the reachability of its ORPort. We set up a service that allows you to test the reachability of your obfs4 port: https://bridges.torproject.org/scan/
Thanks for keeping the Tor network healthy by running relays and bridges!
Thanks, Philipp
