It seems I spoke too soon. After some fiddling around it actually seems
to work with "user proxy".
What does not, however, "just work" is active ftp from a pc running
Windows XP sp2 with the built-in firewall enabled. What fooled me was
that while it is perfectly capable of connecting to a machine on the
local network with active ftp and the firewall turned on, it does not
work when you try to connect to an external server with active ftp as
the XP firewall drops the return packages from the ftp-proxy after the
PORT command. I can't understand why, but it seems to be well known that
the XP firewall does all sorts of weird stuff to ftp clients. Sigh.
Cheers, Martin.
