Failed to send SOLICIT message to ff02::1:2 (Permission denied)

Hey, I do get the following error messages from odhcp:

odhcp6c[16857]: Failed to send RS (Permission denied)

I did read somewhere, that ip -6 route add default dev pppoe-wan resolves the Permission denied error, which it does (not permanent that way). However, it still fails with (Address not available) afterwards.

I did see issue #55. My ISP does support IPv6 via dual stack for sure, but no link local address shows up with ifstatus wan:

It does work with another router (a fritzBox).
