From version 7.4.0, CompleteFTP (Professional and Enterprise Editions only) supports local SSH port forwarding (often known as SSH tunneling). This means SSH tunnels can be established between a client machine and CompleteFTP that other protocols can use.
Why would you use SSH port forwarding (also called SSH tunneling)? There are two reasons - firewalls and security.
Consider the scenario where an employee using a laptop outside the corporate network wants to give a demonstration to a customer using a machine within the corporate network. Perhaps they want to use RDP (the Remote Desktop Protocol) and it has not been set up in secure mode. In this scenario a CompleteFTP server is also within the corporate firewall.
Firewalls
By default, RDP uses port 3389, but say for security reasons the corporate firewall does not permit external connections to this port number. If SSH port forwarding is used, all RDP traffic is transmitted over port 22 (the standard SSH port). There is no need to open the RDP port in the firewall.
