Hello fralacos,

I tried your instructions but I could not make them work for me. Assuming I followed your instructions correctly (and perhaps that is not a valid assumption!), I believe the reason it did not work is because I also need the data ports forwarded down the tunnel, and not just the control port.

The method I outlined above allows for the data ports to be known in advance and therefore forwarded down the tunnel.

Please let me know if I did not follow your method correctly and the data ports should have been forwarded down the tunnel as well?

Thanks and regards,

I got this working using putty 0.60 for setting up a dynamic tunnel, with this kind of tunnel PuTTY provides a local SOCKS 4/4A/5 proxy on a local port. Your FTP client must be set to use this local SOCKS proxy and passive mode.

Not so detailed Instructions:

on PUTTY:
  1. Open putty configuration.
  2. Set up an SSH connection to your SSH server as usual (host, port, etc.)
  3. Go to Connection > SSH > Tunnels.
  4. Fill in source port, this is the port where SOCKS proxy will listen, so you FTP client should be set to use 127.0.0.1:<source port> as socks proxy.
  5. Destination: empty, not used for dynamic tunnels.
  6. Select Dynamic radio button.
  7. (optional) Go back to session and save you settings.
  8. Connect to your SSH server!

on FTP client:
  1. Configure your FTP client to use a SOCKS proxy at 127.0.0.1:<source port>.
  2. Configure your FTP client to use PASSIVE mode.
  3. FTP connection must be opened to actual FTP server address and port, for example 192.168.0.1:21. Note that your SSH server must be able to reach your FTP server at that IP address and port.

PS: I'm a frequently visitor of this forums and got lot of help from here, just now i have this chance to help back so ... hope it helps!

Legend! Long story short I'm in IT, tunnelling etc is a frequent requirement in my role, I knew I wanted to use a dynamic tunnel in PUTTY to get around FTP's damn dual port set-up but hadn't considered adding a proxy to my FTP client!! You are a star, works like a charm!
