Unfortunately not. Libpeer does not work on arduino and other vpn solutions require some spec server. Husarnet working on a library instead of a complete redesign of the idf framework but it will lock into their environment.

I went with a node js server and forwarding every message trought wss to the clients and back.

Other solutions does not exists or would be too difficult to write on my own.

@zekageri Can u give some more details on communication between nodejs side and arduino, and how does nodejs mediates msgs between arduino and webrtc/turn client etc

What i am thinking is : i can have a turn server installed, where arduino will connect... and i can have a nodejs/go/python app on host pc that will work as turn client and that way arduiono can communicate with host pc

However, i have hard time finding out a suitable library, i dont need full wrtc support,

As i said, libpeer does not work with Arduino. And this is the only implementation of a webrtc for esp32. You need to do it with IDF

@zekageri I understand libpeer doesnt work with arduino, i am looking for ideas on what was ur alternative solution,
Also i am not looking for a full webrtc support, a TURN server can be used to get p2p communication working, if i can find a proper client side library for TURN.

Would be great if u can give details about ur nodejs based solution, even if it doesnt use webrtc, STUN or TURN or any thing like that

If nothing works (or easy to implement) i can just go with a reverse tunnel like frp or chisel etc

I have made my own solution. Esp connects to server with native idf websocket client using https. Esp sends every message to server. If the server got any http or ws request from a client it forwards it to the esp32 on websockets. Basically thats it.
