In addition to being able to forward traffic from any port to any port, the traffic is encrypted on its journey because it is passing through an SSH tunnel. Furthermore, the port forwarding has to be started before Syncthing starts, otherwise there be dragons. Port forwarding can be used to set up SSH tunneling for communications between the client and the server or between the client and the firewall/gateway over the Internet, in which case the firewall and server need to be able to connect to each other on the same LAN. It can be really useful to use ssh tunnels and local port forwarding to access servers, databases or more generally services running on remote LAN. After the correct password is entered, there will be no shell since the options -TN were used which prevent ssh from allocating a pseudo-tty. Make sure you choose a random port, preferably higher than 1024 (the superior limit of standard well-known ports). In this blog I’ll be providing instructions for establishing an RDP connection over a reverse SSH tunnel using plink. TTSSH command line.
