Not sure if it's related or not but I've seen weird v6 behaviour on
my workstation for a while which I've been trying to figure out in order
to get enough information together to make a useful report. But since you
have problems in a similar area I'll mention it now before figuring any
more out in case it's relevant.
Trying to connect to any host (directly connected or remote) fails with
EHOSTUNREACH, but the route is there, ndp is there, PF is not in the way
(I see the same with pfctl -d). No difference with the nd6_timer_next diff.
