SSH Portforwarding

When having a remote computer (A) in which you’re trying to access the port
:3000, you can setup a reverse portforwarding with the following command:

$ ssh -L <port that you want to access locally>:localhost:<port that you want to
connect to> <user>@<ip>

$ ssh -L 3000:localhost:3000 [email protected]

This way, you can access http://localhost:3000 and it is actually communicating
with myipaddress:3000.

All securely too!
