try to use "older" kernel versions (or best an openwrt router with an old

onlink flag for routes, some months ago, but on server side, i really doubt
that we anyhow managed to break it recently (and it worked on the systems we
tested it #1

#1 but i can`t recall completely which ones this where, but it included for
sure openwrt whiterussian and kamikaze
