![]() Programs on your server (or elsewhere on the server's network) must be able to connect to server:6000 (or server's routable address, port 6000) to initiate the connection. With this command, a program on the laptop must be listening to port 7000 for connections. If you wanted it to be open to all machines that can contact the server, then you could use ssh -R *:6000:localhost:7000. By default this is only open to connections initiated on the server machine. If you want connections made to server:6000 to be forwarded to laptop:7000, then you could use ssh -R 6000:localhost:7000. Programs on your laptop (or elsewhere on your local network) must be able to connect to your localhost:7000 (or your machine's non-routable address, port 7000) to initiate the connection. With this command, a program on the server must be listening to port 6000 for connections. This restricts the port on your laptop to connections initiated on the laptop itself. If the connections originate on your laptop then you could slightly amend this to: ssh -L localhost:7000:server:6000. If you want connections made to laptop:7000 to be forwarded to server:6000, then you could use ssh -L 7000:server:6000. Since I don't know putty, I'll give the corresponding commands from OpenSSH hopefully it'll be easy to find the corresponding options in the GUI config boxes of putty. The connection will always be initiated from your laptop (because it cannot be directly addressed from the other machine) but you will use one or the other connection forwarding arguments based on how you want the port forwarding to work. you can access the ftp server directly but you don't want to send your data (username/password/files) without encryption over the internet.The direction of your arrows has no relationship to which machine has publicly routable IP addresses - you need to know which direction you want your arrow to go based on the problem you're trying to solve.you cannot access the ftp server directly (external connections to the ftp server are blocked for security reasons), or.Possible uses: your PC is on your home network, the SSH and FTP servers are behind your company's router/firewall, and: Then execute Filezilla client using:Įncryption: Only use plain FTP (insecure) Proxy port: XXXX (the SSH tunnel source port number, see PuTTY configuration above)įirst execute PuTTY to create the desired SSH tunnel (you will be asked to provide username/password to login to the SSH server).

The SSH server is a remote host that runs a SSH service (typically a Linux/Unix/BSD host). In this mode, PuTTY acts as a proxy server.
