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/forward both ports. You can use our reachability test to see if your obfs4 port is reachable from the Internet.
Are you firewalling your NetBSD? If so, make sure that
obfs4proxy can talk to
tor over the loopback interface - do not forget to allow the ExtORPort.

# echo "tor=YES" >> /etc/rc.conf
# /etc/rc.d/tor start
4. Monitor your logs
To confirm your bridge is running with no issues, you should see something like this:
# tail /var/log/messages
[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.
