Advanced Moves- Remote SSH IoT Reverse Tunneling
Reverse SSH tunneling is a more advanced way of doing things that lets you connect to IoT devices that are behind firewalls in a very secure manner. This method involves setting up an SSH server on a public computer and then making a "reverse tunnel" back to your local IoT device. It is a bit like having your IoT device call out to the public server and say, "Hey, I'm here, you can reach me through this connection," rather than the other way around. This is, you know, particularly useful when your IoT device is deep inside a network and cannot easily be reached from the outside directly.
This technique is quite powerful for situations where the IoT device itself cannot easily initiate an incoming connection because of firewall rules. The device makes an outgoing connection to a server you control on the internet, and then you can use that outgoing connection to send commands back to the device. This is, actually, a very clever workaround for many common network restrictions. Remote SSH access for IoT devices that are behind routers is both possible and quite manageable with good planning, proper setup, and careful security steps.
