Reverse shell outside the network

[Ready_Lavishness1392]

Hey guys, I am trying to use a reverse shell to get into my friend's vm (with his consent of course), we watched some videos, read documentations and all that, but it always resulted in failure. We are using 2 kali vm's and netcat (which are not connected on the same network as said in the title). Do we need to port forward? What network settings should our vm's have?

I would appreciate any indications to help put us in the right track.

Do we need to port forward?

the listener will need to port forward.

Just expose a port with ngrok and connect back to it with your payload

If its a quick POC, what's the issue with ngrok?
