How can I use a tunnel to access my AMP panel from outside of my network?

How do I connect to the AMP Panel from an external network using a tunnel service (playit.gg)?

I would like a friend to be able to help manage the panel/servers from their house, but I can’t figure out the correct combo of ports and IP configurations to get it to work.

I’m testing it on my laptop using a hotspot connection as well to simulate being outside my network.

Which ports and IPs should I enter into the tunnel?
Do I set it to UDP or TCP?
Do I have to type “http://” in the browser before the IP, to access the panel?
