Setting to "auto" is good enough. Don't configure an external IP address
for ExtORPort. "auto" will cause it to listen on 127.0.0.1 on a random
port.

ExtORPort is only used for localhost communication between obfs4proxy
and tor. It shouldn't be exposed externally. It's needed in order to
have the bridge contribute to user metrics.

You mean fallback directories? I don't know, it sounds okay.

That is okay.
