Eh that's what I did :)
I'm using unix-systems for quite a long time now, it's just this thing
that really doesn't want to work.
I got it working now, one of the problems was the test machine in my
internal network (an old openbsd machine). It didn't accept it's own ip
until I messed with kernel-options and rtsol (weird... very weird); it
refused to accept packets until I initialised it with rtsol (plug&play),
then the manual 3ffe:b80:1c8::2 worked too.
