Yep, thanks - that did the trick.
I wonder why it isn't sufficient to set 'echo 1 > /proc/sys/net/ipv6/conf/lowpan0/forwarding' on that specific lowpan interface? I tried it, but `radvd` still complains (debug level 5) that forwarding is 0. However, it works by enabling it for all IPv6 interfaces as you suggested.

mhm, I'm using default Raspbian with RPI-Linux+DTS-overlay 'at86rf233' as it is cause a fast and easy setup - and until now, this was sufficient for my test cases ...
