Introduction to SSH Port Forwarding

The following diagram shows how you can use FSLink to secure your connections:

The client program doesn't connect to the server program over Internet (or other non-secure network) directly. Instead it connects to FSLink over a local or trusted network (or FSLink can be run on the same machine as the client program).

FSLink is configured to maintain a secured link with the SSH server (like Foxit WAC Server or other SSH servers supporting SSH1 or SSH2 protocol) over a non-secure network, and all communications betweek FSLink and the SSH server will be encrypted and verified.

Once your client connects to FSLink, it will forward the connection to the SSH server, where the connection is further forwarded to a configured server program, over a local or trusted network (or the server program can be run on the SSH server machine).

You don't have to alter your client or server program (although some configurations might need to be changed, for example, the server address in client program must be changed), but you can still ensure all your communications with the server, over the non-secure network, will be protected.
