      Using pfSense built on Wed Dec 30 22:53:53 CST 2015 (issue also seen on 2.2.5 before)

      Clients receive correcy IPv4 DNS server address from pfSense DHCP service.
      Now trying to hand-out correct IPv6 DNS server address (physical same als IPv6 server of course) to clients, but I notice the pfSense IPv6 address is hand-out as first IPv6 DNS server address. When I google it, this post gives good description:
      https://www.reddit.com/r/PFSENSE/comments/3s45ea/pfsense_giving_itself_out_as_dns_server_to_ipv6/

      Config:
      PPPoE WAN connection with native /48 IPv6
      LAN Interface IPv6 with track interface (so no RA)

      Just want to give clients one (LAN Internal) IPv4+IPv6 address
      Edit: On this moment pfSense hands out own IPv6 address as IPv6 DNS server to clients and gives time-out problem on client because pfSense DNS server is not used

      Do I miss something in my setup?

        What else do you expect other than what you're experiencing? Which DNS server do you run on pfSense ? IPv6 is different from IPv4, it uses RA. pfSense runs Dnsmasq or Unbound. pfSense talks with ISP or root-servers, LAN clients talks with pfSense.

        Besides, why do you use Track Interface, it is far from a professional setup imo.

          "Config: PPPoE WAN connection with native /48 IPv6"

          So you have a /48 routed to you??  Why would you be using track on lan side then?

          I would really suggest you understand how ipv6 works before trying to deploy it..  So do you have a /48 actually routed, or does your wan interface get a prefix of /48 address?  That doesn't sound like a correct sort of deployment??

          I would use /64 out of that /48 and put them on your lan, you can then setup RA and or dhcpv6 how you want it to make sure your ipv6 clients discovery and or get assigned the ipv6 nameserver(s) you want them to use.
