The post contains conflicting advice.

This advice is correct.

> Leave your ExtORPort set to auto for diversity reasons. I have a firewall enabled on my Debian bridge with very restrictive port settings. I had to make port forwards for the given obfs ports in iptables (easy with gufw) as well as in my hardware (internet-)firewall to make things work. So I am not so sure that the ExORPort is for local connections only as mentioned by Rodger (please let me know if I am wrong here).

This advice confuses ExtORPort (which is local) and

ServerTransportListenAddr (which is used for obfs4).
