How can I access another computer's terminal outside the local network?

Question

I would like to access the terminal of another computer that is outside my local network.

Answer 1

In most cases just as you are running under a local network the other computer might also be running under a local network. That would make it impossible for you to connect directly that computer's IP unless the configured port forwarding of their router to go to that specific computer.

You could setup a common VPN (virtual private network) that would put both you and the other computer on the same network. Then you would access the computer's IP (from the vpn) the same way you access computers on your local network.

Some information on setting up a Virtual Private Network can be found here.
