      Hi,

      pfsense 2.3.2-RELEASE-p1
      FritzOS 06.80

      I have a pfSense system running on a VDSL link with a static IPv6 configuration + a static routed 2001:1111:4444::/48.
      Now I would like to run a Fritzbox behind that pfSense while requesting a prefix through prefix delegation.

      I set up everything like I think it's right, but as it seems the FB asks for a prefix, but the pfSense just doesn't answer. What am I doing wrong. Here come the details.

      pfSense:
      downstream interface IP: 2001:1111:4444:1c::/64
      Enable DHCPv6 server on interface VOIP
      DHCPv6 Server range from: 2001:1111:4444:1c::f
      DHCPv6 Server range to: 2001:1111:4444:1c::ffff
      DHCPv6 Server PD range from: 2001:1111:4444:f000::
      DHCPv6 Server PD range to: 2001:1111:4444:ff00::
      DHCPv6 Server PD size: 60
      Router Advertisement is set to Managed with DNS Settings set to "Use same as DHCPv6 server"

      FB (translated from German):
      use native IPv6
      global address exclusively via DHCPv6
      As a matter of fact I tried every possible setting in the FB. It doesn't change.

      Then I sniffed on pfsense at this VOIP interface with wireshark to see what happens.
      I see a DHCPv6 Solicitation originating from the FB headed to ff02::1:2.

      Please help!
