<hsowa> ah this is probably the problem
<hsowa> fe80::5054:ff:fe96:951f
<hsowa> is your router
<hsowa> which is absolutely correct
<hsowa> but you can't forward LL frames
<hsowa> (we don't proxy that one)
Comment 1 Hannes Frederic Sowa 2016-05-27 15:42:02 UTC 
Implement proxy_ndp "more" correctly by following https://tools.ietf.org/html/rfc4389

Also allow to proxy complete subnets instead of just routers and provide a way to rewrite link local addresses to local ones while proxying.
