What is a proxy tunnel
6. In the 'SOCKS Host' box enter 'localhost' and for 'Port' enter '31415' (or whatever you set your SSH Tunnel up with). 7. Make sure 'SOCKS v5' is selected and select the 'OK' button to save. As long as your PuTTY SSH connection remains connected, your proxy tunnel will be open and you will be able to use the internet through this proxy.
