      Hi,

      I think I have this set up right as far as IPV4, but I am not sure what to do with IPV6:

      in pfSense:
      disable dhcp server
      disable dns forwarder/127.0.0.1 dns (in general settings)
      disable dns resolver

      Interface ipv6 settings:
      dhcp6 (WAN)
      track interface (LAN)
      block private and loopbacks (WAN)
      send ipv6 prefix hint (WAN)
      resolution /64  (WAN) (it's a residential connection)
      prefix id 0 (LAN)

      Firewall rule:
      Echo request from ICMPv6

      This setup seems to be working pretty well, as far as the internet is concerned.  ipv6-test.com gives me a 19/20 (in their eyes all I'm missing is a DDNS name for my WAN, apparently).

      However, my domain controllers complain that I do not have static IPV6 addresses.  I have very limited understanding of IPV6 so far, can anyone give me an idea of what I should do?

      Thank you so much,
      Avery

        Essentially, on IPv6, like IPv4, you don't have a static address, unless specifically assigned.  However, you do have what should be very consistent address.  IPv6 used DHCPv6-PD, which assigns your prefixes.  It shouldn't normally change, though it is possible.

        I haven't lost my mind. It's around here...somewhere...

          Had a similar question myself, still doesn't seem to be any generally accepted "best practices".
