Yes, passive mode is the default.

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.


HTH,
