AFAIK, passive is also the only _working_ mode for Squid-origin communication. FTP active mode is broken for Squid-origin connections (and has been broken for many years IIRC). Native FTP proxy (that Amos has mentioned in his response) supports both passive and active FTP client-Squid connections. The ftp_passive directive has no effect on those FTP client-Squid connections. Native FTP proxy suffers from the same "active mode does not work" problem mentioned above as far as Squid-origin connections are concerned.
