This feature allows to create and use port forwarding mode SSH tunnel sessions just like with [OpenSSH|https://www.ssh.com/academy/ssh/tunneling/example]. \\
!!Configuration steps:\\
\\
__1.) add an SSH tunnel instance on Preferences ->[Tunnels|tunnels] page, user configurable.__  Port number doesn't really matter, not used.\\

\\

\\
__3.) connect with openssh tunnel mode no console__\\
\\
{{{ssh -v -N -L 8888:localhost:8080 testtunnel@192.168.3.102 -oPort=2222}}}\\
\\
__where you will replace ,as per your specific settings, the IPs\hostnames and port numbers as necessary:__\\
\\
;8888: is the local port number you will connect to with a browser like __http://127.0.0.1:8888/__ \\ 
;localhost: is the remote forward IP or host name we tell the ssh (Crush server) to connect the tunneled port . This example is a loopback tunnel to the Crush server itself, we connect to the HTTP port 8080 listener on the same host. \\
;8080: is the remote port to tunnel to \\
;192.168.3.102: is the Crush server's publicly accessible IP\\ 
;2222:  is the Crush server's publicly accessible SFTP port \\
;testtunnel: is the tunnel user login name. \\
