A quick reminder for myself how to expose a local machine using an intermediate server
Raw
SSH port forwarding cheatsheet.md

Quick start

Forward port 22 on local machine as server:22222

ssh -R 22222:localhost:22 server_user@server -p PORT

Expose this port on the server to the world using socat *

socat TCP-LISTEN:22223,fork,bind=0.0.0.0 TCP:localhost:22222

Now you can connect to the local machine from outside of the local network

ssh local_user@server -p 22223
