Most developers have no idea what Reverse SSH Tunnel actually does.

You need to access your home machine from anywhere but your router blocks all inbound connections.

Steps:
1. A reverse SSH tunnel lets your home machine call out to a server and make itself reachable through it.
2. A normal tunnel goes from you to the server — a reverse tunnel goes from the server back to you.
3. Your home machine initiates the outbound connection which bypasses NAT and firewalls.
4. The remote server listens on a port and forwards those connections back to your home machine.
5. Create a reverse tunnel from your home machine to a remote server.
6. ssh -N -R 2222:localhost:22 user@remote-server
7. From anywhere connect to the remote server on port 2222 and you arrive at your home machine.
8. A reverse tunnel is how you reach a machine behind NAT without touching the router.
9. Now you know what a reverse SSH tunnel does — and when to use it instead of port forwarding.
