Feedback requested:FTP ALG for IPv6-to-IPv4 translation

[Iljitsch van Beijnum <[e-mail]>]

Hi all,

In the BEHAVE wg we're working on IPv6-to-IPv4 translation. One  
prominent protocol that has trouble with this is FTP, so we're  
thinking of making an FTP ALG part of this. I wrote a draft on how to  
do this, and I would very much like some feedback. The draft is only 6  
pages.

Thanks,

Iljitsch van Beijnum

> Abstract:
> The only FTP mode that works without changes through an IPv6-to-IPv4
> translator is extended passive, introduced in 1998.  However, many
> existing FTP servers don't support this mode, making it impossible to
