To FTP from behind a masquerading firewall requires that the
masquerading machine be configured to allow it.  If the
firewall is a Linux box using the kernel's masquerading features,
the firewall administrator needs to load the `ip_masq_ftp'
module; other firewalls will require other measures.

Using a conventional ftp proxy typically requires using
SOCKS-aware clients, which may not be possible depending on the
client operating system and specific clients required.
