The IESG has received a request from the Behavior Engineering for Hindrance Avoidance WG (behave) to consider the following document: - 'An FTP ALG for IPv6-to-IPv4 translation' <draft-ietf-behave-ftp64-10.txt> as a Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2011-06-03. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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, it is important that in the situation 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, FTP is made to work through these translators as best it can. 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.
