      Hi All,

      i've recently had a backup internet connection installed using BT Business in the UK,

      The supplied router has been changed to bridged mode, and i'm able to PPPoE login fine over IPv4, however, the IPv6 isn't working for me,

      i've tried numerous combinations of the check boxes (in combinations found by web searches) but don't seem to get an address / delegation.

      has any one got a working implementation?,
      ideally i want to be able to run NPt on the IPv6 range received if at all possible,
      with my VLAN's running seperate /64's

      here's the log from PPP for the following config
      09607ea3-8b2a-4d21-b85f-9a03097fe5d6-image.png
      and a vlan lan interface setting

        huh... so had to enable router advertisements as well on the VLAN Lan 45 interface,
        then it assigned it an ip address out of pressumably the range recieved.

        doesn't solve what i want, (which may be impossible?)

        which is to use ULA internally (already set up with fd16:: ranges on the LAN / internal VLANS)
        and use NPt to map onto the external WAN IPv6 ranges.

          @MHall-0 are you using BT Fibre Modem by chance? White box ? If so. The White Fibre modem doesn’t work with IPv6 when I was testing it.

            @VioletDragon No,

            Bt Smart Hub 2

            for now i've backed out of bridged mode,
            i've gone back to NAT'ing everything through the addresses the BT router gives pfSense

              @MHall-0 double NAT will cause problems. I have held off with IPv6 with both ISPs I am with. The Smarthub I have doesn’t have Bridge mode support. Can you get IPv6 working if you use a Windows or Linux ? That would be something to test.
