hi Benedikt,

I've tweaked the subject, so the folks can filter it out if needed,
given that the discussion is way above L4 :-)

True. FTP active mode. It's immortal. :-)

The problem  I think did not really exist at the time IPv6 was defined - so
it is not fair to say we "have had" an occasion. And now it is
