So every time you connect to the server you need to supply your private key for authentication. Then create a second PuTTY session to localhost using whichever port number you set up. In this age of cloud, all the Linux servers deployed in the cloud come with default key-based authentication Authentication is done using pair of keys: Private key (with user) and Public key (stored on server). For SSH, although I don't know if you can do it in one step, you can use PuTTY to set up a local port which tunnels through the remote server and redirects to the second (internal) server. Traditionally we used to have password-based authentication for Linux servers.
