SSH Tunnelling

Connect local port to server port

Introduction

An SSH tunnel creates a connection between a port on your local machine and a address + port on the server, and tunnels the data to the server over SSH on port 22 to the server address + port.

This is done so that it doesn't get blocked by any firewalls or security groups (assuming only SSH connections are allowed to the server). After the data reaches the SSH server it gets forwarded to the address + port you specified when you created the SSH tunnel.

An important detail here is that the destination address + port are accessed from the context of the server, so localhost or 127.0.0.1 refer to the server machine on the destination side of the tunnel, not your local machine.
