Yes, this is the way FTP works. Active mode might work a little
better, but would require the server to connect back to the client.
Not sure if libcurl supports active mode anyway.

That won't work.

Maybe you can download the file via normal GET ftp://blah/path/to/file
to the proxy and then after that use CONNECT and QUOTE to remove the
file? That way you would not need port 20 or the random port because
there would be no data channel. Only a command channel.
