I wonder how to define to use a proxy for FTP access - is there a way to add port 21 to the config of the atom?
Any hint highly appreciated
That's not possible with the FTP connector. However, the SFTP connector should support it, see SFTP connection. If you have the option to switch to SFTP, it's a better choice.
Also see idea: Proxy aware connectors
Thank you very much for the information - unfortunately, I don't have a choice to switch to SFTP :-(
