How do I use a graphical SFTP client, such as FileZilla, with an IPv6-only proServer (proServer2G)?

First, the information provided in the article "How do I connect to an IPv6-only proServer (proServer2G)? " regarding the SSH connection applies: if you have IPv6 connectivity at your workstation, no further action is required—the connection works as usual.

If you only have an IPv4 uplink locally, please read this entry first and make sure you can successfully connect to the proServer via the command line (Mac OS, BSD, Linux) or PuTTY (Windows).

The final step is then straightforward. First, establish a command-line connection as described above (using a jump host), but also add port forwarding. Use the following additional parameters for this:

ssh -L 2222:127.0.0.1:22 vproWXYZ

Putty also has a dialog where you can add port forwarding to a connection. Please leave the established command-line session open for now.

Now launch FileZilla, for example, and specify “localhost” as the server for the SFTP connection and “2222” as the port—enter the remaining parameters (username, key file) as usual.
