ssh tunnelling

The problem

For example, you're on local.example.com and want to connect to remote.example.com on port 25 (SMTP), but a firewall is stopping you.

You will need

• ssh access to remote.example.com, or to another machine that can access remote.example.com on port 25.

How it's done

We get our ssh client to listen on a port on local.example.com (we'll use 1025). This will forward traffic through to remote.example.com on port 25.
