Currently no IPv6 nameservers are distributed via dhcp when using the nat64 wireless LAN. Also the regular IPv6 nameservers are not yet translating IPv4 IN A responses to IPv6 mapped IPv4 i.e. they return IN A instead of IN AAAA records which cannot work via NAT64 i.e. IPv6-only connections.
Regular Nameservers should not make the NAT64 translation. But DHCPv6 should be available now on the NAT64 vlans. -- falk
