Say, you want to connect to a database server running at port … The best way to understand these is by an example, let’s start with local port forwarding.
Local port forwarding allows you to forward traffic on a port of your local computer to the SSH server, which is forwarded to a destination server. How to Reverse SSH Port Forwarding. In order to SSH into a machine behind a firewall you will need to use Reverse SSH Port Forwarding.
Imagine you’re on a private …
