VOLUMIO2 - WebUi Port

I’m starting now with volumio 2, and it’s been great!
One thing that i had on Volumio 1.55 was the connection to the Webui from outside the local LAN, changing the port on the nginx. On this new version the nginx is gone, and i can’t find a way to forward the Webui to a different port.

Any clue?

Tks in advance
