How to Connect to a VNC Server Using SSH Tunnel with Putty and Port Forward
If you connect to a remote desktop using the Virtual Network Computing (VNC) protocol, your connection may not be secure. Some VNC clients, such as the popular TightVNC, do not encrypt your connection after the initial login phase. To work around this problem, you can tunnel a VNC connection through a Secure Shell (SSH) tunnel.
An SSH tunnel not only provides a fully secure connection for VNC, but it also allows you to use VNC connections when the typical VNC port (port 5901) is blocked. Some corporate networks block common ports like port 5901 for added security, so tunneling VNC over SSH allows you to get around this problem.
Windows 10 does have a built-in SSH client, thanks to Windows PowerShell, but this is a recent development. If you want to know how to tunnel VNC over SSH, it is recommended that you use PuTTY to connect to your SSH server.
