Oops forgot about that one again :)
On non-forwarding hosts (or even per-interface?) it does work.
Hmm in that respect it should probably give out some kind of
notification as it's really something one looks over ;)
Then again it doesn't quite explain his "after a few seconds it doesn't
ping anymore" behaviour.
