1. Install packages
pkg_add tor obfs4proxy
2. Edit your Tor config file
Usually located at
/etc/tor/torrc, and replace its content with:
# Replace "TODO1" with a Tor port of your choice. This port must be externally
# reachable. Avoid port 9001 because it's commonly associated with Tor and
# censors may be scanning the Internet for this port.
ServerTransportPlugin obfs4 exec /usr/local/bin/obfs4proxy
# Replace "TODO2" with an obfs4 port of your choice. This port must be
# externally reachable and must be different from the one specified for ORPort.
# Avoid port 9001 because it's commonly associated with
# Tor and censors may be scanning the Internet for this port.
ServerTransportListenAddr obfs4 0.0.0.0:TODO2
# Local communication port between Tor and obfs4. Always set this to "auto".
# "Ext" means "extended", not "external". Don't try to set a specific port
# number, nor listen on 0.0.0.0.
# Replace "<email@example.com>" with your email address so we can contact you if
# there are problems with your bridge. This is optional but encouraged.
# Pick a nickname that you like for your bridge. This is optional.
Log notice file /var/log/tor/notices.log
Don't forget to change the
- Note that both Tor's OR port and its obfs4 port must be reachable. If your bridge is behind a firewall or NAT, make sure to open both ports. You can use our reachability test to see if your obfs4 port is reachable from the Internet.
3. Create the tor log directory and give it the correct permissions:
chown _tor /var/log/tor
4. Start the tor daemon and make sure it starts at boot:
rcctl enable tor
rcctl start tor
5. Monitor your logs
To confirm your bridge is running with no issues, you should see something like this (
[notice] Your Tor server's identity key fingerprint is '<NICKNAME> <FINGERPRINT>'
[notice] Your Tor bridge's hashed identity key fingerprint is '<NICKNAME> <HASHED FINGERPRINT>'
[notice] Registered server transport 'obfs4' at '[::]:46396'
[notice] Tor has successfully opened a circuit. Looks like client functionality is working.
[notice] Bootstrapped 100%: Done
[notice] Now checking whether ORPort <redacted>:3818 is reachable... (this may take up to 20 minutes -- look for log messages indicating success)
[notice] Self-testing indicates your ORPort is reachable from the outside. Excellent. Publishing server descriptor.
