Aram Hăvărneanu 2019 7 29 https://xw.is/0006/ 0006 /0006/ OpenSSH › Connect to laptop (behind NAT) using intermediary server We'll use a combination of ssh remote and local port forwarding in order to expose the laptop's ssh port outside the NAT. The laptop must initiate the forwarding. Aram Hăvărneanu 2019 7 29 On the server Make sure you have an account that the laptop can connect to through ssh. Aram Hăvărneanu 2019 7 29 On the laptop This will initiate a connection to the server (from the laptop), and it will set-up a remote port forward such that dialing localhost:12345 on the server will forward to localhost:22 on the laptop. ssh -N -R 12345:localhost:22 harieta@freedom.mgk.ro Aram Hăvărneanu 2019 7 29 On the other client This will connect to the server, and then set-up a local port forward (from the other client to the server) such that dialing localhost:12345 on the client will connect to localhost:12345 on the server. Of course, localhost:12345 on the server just forwards to localhost:22 on the laptop. ssh -N -L 12345:localhost:12345 freedom.mgk.ro Then from another terminal (still on the other client) you can: ssh -p 12345 ubuntu@localhost And should reach localhost:22 on the laptop.
