A maintained fork of SSHTunnel can be found at https://github.com/MacThings/SSHTunnel The application has been updated to work with latest versions of macOS.
SSHTunnel is an OS X application that allows you to easily create SSH tunnels from your computer to a remote host (like a website) through a SSH server. This SSH tunnel can bypass the firewall rules in a secure way. So if you are at work, and you can't access YouTube?, just create a SSH tunnel, and your ready to go!
