基本解释

This section describes the steps needed to configure SSH client (PuTTY, in this example) so that it can forward the traffic of localhost to the destined port on remote machine.

When establishing an inbound tunnel—formally called a remote forward—the roles of proxyhost and targethost are reversed: The target is your local machine, and the proxy is the remote machine.
