The remote port is chosen by the remove ftp server, so curl shouldn't
behave any differently from any other client in the port number is connects
to. You can try disabling passive mode altogether by setting CURLOPT_FTPPORT
and see if that makes a difference, but that opens up a whole new set of
potential problems.
