It will connect, but nothing more, something is dropping packets I
think.
Unfortunatly these boxes all take the same route over amsterdam.intouch
(2001:6e0::2)
so the problem could be behind that box, though I don't think it's that
one as I kinda trust it :)
Odd thing: connecting to port 80 on the ftp6.netbsd.org doesn't get
refused.
Is this thing a v6 loadbalancer ? :)

Greets,
