As a form of test I've put rtadvd inside the same non-vnet jail and I can see RA message arrive to the vnet jail. I though I "disconnected" something concerning IPv6, but that's obviously not the case. Let's take a step back. Is there any howto/tutorial on how to put isc-dhcpd6 in a non-vnet jail? I don't care if it's jail.conf or some jail manager. Can I somehow see where packets end up, like dtrace? Should I try some other server/client for DHCPv6? If I can make it work in any scenario, that would be good starting point for me to figure out what's wrong with my current setup.
