That's because it will work when the client is behind a firewall that 
doesn't support an FTP proxy.  Passive FTP will fail if the FTP server 
is behind a firewall that doesn't support FTP proxy.  If both client 
and server are behind firewalls, FTP will not work at all unless one of 
the firewalls supports an FTP proxy or is open enough to allow the 
protocol to work -- port or passive FTP.
