Using remote forwarding

In the previous section, we looked at the ability to forward local connection attempts to a remote machine.

In this section, we're going to look at something very similar: remote forwarding.

With remote forwarding, connection attempts made to a specified address and port on a remote machine are passed back through the SSH tunnel you've set up, and are processed on the local machine (your client).

Start on centos1.

Before we start it's worth noting that remote forwarding is a great way to punch holes out of networks, which means that it can also be a nightmare for security professionals charged with maintaining a network. With great power comes great etc.
