I have struggled with a similar problem a few years back. Can it be that
the upstream equipment does not create a route for the delegated prefix
pointing to your openbsd machine?
This would explain why you see neighbour solicitations on the outside
interface. The upstream router is not aware that the prefix should be
routed to you.
Yes, I believe it to be te problem. The prefix is delegated to the CPE,
not the OpenBSD machine. When I run the dhcp6c program, it asks for a
prefix delegation from the CPE and gets one. But I don't think that the
CPE is trully delegating the prefix, hence that's why he's issuing
neighbor solicitation messages. Someone pointed to me that I'll need to
use a ndp proxy or use the openbsd machine as a bridge filter. I can't
change the CPE configuration, it's locked by my ISP.
