      @milonic in the documentation of theOtherSense they write that an earlier version of that guide reference setting up WAN IPv6 with a static ip. But that this is since not advised anymore. Maybe yours is still static because you requested it 6 years ago?

      https://docs.opnsense.org/manual/how-tos/IPv6_ZenUK.html

      "Note: The previous version of this guide provided instructions to configure WAN interface statically. Zen have advised that they are now phasing out static configuration and therefore recommend customers to switch to DHCPv6 for WAN interface."

        @patient0 Thanks for your help with this, it's appreciated.

        So, version I'm running is 2.7.2 - I did upgrade but the servers are HP Proliants and they won't boot properly after upgrading: https://forum.pfsense.com/topic/199019/fresh-install-of-version-2.8-fails-to-boot - I'll see if I can find a PC and a dual card and test it with 2.8.1 I'm not convinced it will help though, but worth a shot.

        I can't ping anything in the outside world. Local IPV6 is working fine if I use static addressing. Switching back to DHCP fails with lots of errors.

        Anyway, I managed to get a new test system up and running and can confirm that out of the box is exactly the same. From a new install of pfSense all I had to do was set PPPOE username and password and set the DHCPv6 prefix, that's all I needed to do - the rest of the pfSense settings now appear to be geared towards IPV6 out of the box. Even LAN defaults to Tracked configuration type. Still no v6 IP Address for me though.

        You mentioned getting a Static address, that is something I asked a Zen tech support person how to do and the response was that they did not know. They then confimed that they didn't know much about IPv6, even though they'd been on several courses and explained how complicated it all was. What I was asking was info on IPv6 Gateways but they were clueless. So, if I do contact them again, I'll need some evidence that it's their issue, if it is.

        So the next thing for me to do now is to find the original router that Zen sent and see how that works. That was one of the things the Zen person said, was that they'd only support the FritzBoz.

        I'll let you know the outcome, if I can find it.

          @milonic said in IPV6 with Zen, not receiving an IP Address:

          Should I not also have a public IPV6 Address for WAN?

          Not necessarily. Some ISPs don't provide one and if they do, you have to allow it in your configuration. If you have Request only an IPv6 prefix selected, you won't get one.

          With IPv6, the link local address is often used for routing.

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

            Hello,

            Could you post the results from "Status:Interfaces".

            zen does not offer a global IPV6 address for the gateway. I would recommend setting a monitor IP to something like 8.8.88.

            Chers

              @FollyDude-0 Sure, here it is:

              IPv6 Gateway looks local. Is that what I should expect?

                Thanks for your response.

                Yes, you will get a link-local address for the gateway this is normal for zen.co.uk

                Could your verify "Allow IPv6" is set in "System:Advanced:Networking"?

                  @FollyDude-0 Yes, it's definitely ticked - IPv6 is allowed

                    Do you still have the router zen supplied to you originally? If so, you could test IPV6 there as a reference that there are no external issues.

                    One more question? Are you DSL, FTTC, or Full Fibre.

                      @FollyDude-0 I'm still trying to find it, not sure if I binned it. I might ask if I can borrow one if I can't find it.

                      We are on FTTP with a /29 - works pretty good.

                        Finally got this sorted.

                        Zen offered a loan router as I couldn't find the original and it arrived next day, which was nice.

                        Then, after spending over an hour on the phone to a tech person they finally passed the issue over to their IPv6 team who rebuilt the connection and all is now fine.

                        Well, I say all is fine - After I configured everything I started receiving reports that xbox was not working and sure enough xbox.com is painfully slow to load when connecting with IPv6 - I'll look into that one day, could be DNS related.

                        All I really needed to do was get some servers connected so I can play with DNS AAAA records and get some web servers running IPv6. Had to disable the local DHCPv6 server as it either leases addresses to all or nothing. Couldn't find a way of only releasing the static entries so ended up with static IPv6 addresses for just the servers I wanted.

                        Everything seems to be OK for now.

                        Thanks all for your replies and help.
