Hello - new list-subscriber here.
Need a little help debugging IPv6 on OpenBSD 5.7. I've got a VMware VM
running as a router. IPv4 is working beautifully. V6 is not working
for some reason. I'm unable to even ping6 the system's local interfaces.
I've cleared all v6 interface settings and am trying to bring them up
one interface at a time while debugging but still no luck.
link-local and global addresses are not responding. PF is disabled
while troubleshooting.
I've included some relevant v6 settings and outputs in case it sheds
some light or gives any ideas.

Does anyone have any ideas. I'm betting it's a face-palm level user
error that I'm just not seeing.
Any help is appreciated.
Thanks,
