The File Transfer Protocol (FTP) has a very long history, and despite
the fact that today other options exist to perform file transfers,
FTP is still in common use. As such, in situations where some client
computers only have IPv6 connectivity while many servers are still
IPv4-only and IPv6-to-IPv4 translators are used to bridge that gap,
it is important that FTP is made to work through these translators to
the best possible extent.
FTP has an active and a passive mode, both as original commands that
are IPv4-specific and as extended, IP version agnostic commands. The
only FTP mode that works without changes through an IPv6-to-IPv4
translator is extended passive. However, many existing FTP servers
do not support this mode, and some clients do not ask for it. This
document specifies a middlebox that may solve this mismatch.
