again, wicked's supposed to be drop-in, using prior configs. something's clearly off here.
question: is it config ? or a bug?
Have you tried using the following route table entries: default via fe80:: dev sit1 metric 1024 OR default dev sit1 metric 1024 ---> route according to manual config presented on HE.net I was able to successfully (using HE.net tunneling and a sit tunnel configured via wicked) `ping6 google.com`. I tried pinging 2001:hhh:hhhh:hhh::1 as well, but saw the same Address Unreachable error you described. I tried this with a sit tunnel created under wicked, and with one created via `ip tunnel`. Both showed the same results. If you are still experiencing problems after changing the routing entries, please do file a bug with all necessary logs as described in https://en.opensuse.org/openSUSE:Bugreport_wicked. This will help us debug further. Thanks, Karol
