      Hi!

      I'm getting a /56 dynamic prefix from my ISP (Unitymedia Germany). On WAN I have setup DHCP6 and /56 prefix deligation size. LAN is set to Track Interface. Then everything works but no multiwan. Because of that I changed LAN from Track Interface to DHCP6 too. Then the LAN interface gets an IP from my ISP's prefix and everything is working. But if my WAN goes down and comes up again, it doesn't get an IPv6 anymore. Clients still working. If I reboot the machine, nothing get's an IPv6 adress.

      I don't see the point what is wrong or why this is happening. Any hints? It would be a dream if my clients would use DHCPv6 and I don't have to use the Track Interface option on LAN.

      Also the Log shows:

        Now only WAN gets an IPv6 address, LAN doesn't. Also clients can't reach the IPv6 internet.

            After I got it working, now it's not working again after reboot. I don't know why :( WAN gets an IPv6, LAN doesn't.

            WAN is igb0, LAN is igb2.

              Looks like they are sending you a /62 prefix and not a /56.

                But why? After 3 reboots of pfSense I now got my IPv6 connectivity back with /56 on WAN. Also with /62 it should be possible to get an IPv6 on my LAN side from the same net.

                  I may have been misreading that log as it does say earlier in the log that it has a /56. (Reverse order logs are evil)

                  How exactly were you attempting to trigger an update of the addresses? When using tracked interfaces it works kind of weird. The dhcp6c client itself is what applies a tracked address to a tracking interface, but the dhcp6c client only runs on the interface being tracked.

                  So if you touch LAN in a way that makes the IPv6 address go away, then you have to save/apply on WAN to kick dhcp6c into reapplying the addresses.

                  That should happen on any reboot, though. It shouldn't have taken three, certainly. Maybe it wasn't given enough time.

                    I did apply WAN many times and LAN as well. Sometimes dhcp6c doesn't do anything to obtain an IPv6 adress. You can't see anything in the DHCP logs. After reboot it starts again but with the errors above. Reboot, reboot, reboot maybe then it works flawless without touching anything.

                    I know it's strange, but it makes crazy.

                      OK right now IPv6 magically stopped working again! The interfaces still have IPv6 addresses and clients as well, but I can't get any connectivity over IPv6 from clients!

                        @mrsunfire said in 2.4.4 IPv6 is strange:

                        Oct 9 09:16:03 dhcp6c 34431 add an address 2a02:xxx/128 on igb0
                        Oct 9 09:16:03 php-fpm 40667 /rc.newwanipv6: rc.newwanipv6: on (IP address: 2a02:xxx) (interface: wan) (real interface: igb0).

                        It added an address to WAN

                        Oct 9 09:16:03 dhcp6c 34431 add an address 2a02:xxx/64 on igb2

                        And to LAN

                        If IPv6 works from the firewall at that point, but not clients, it could be upstream routing somehow, like maybe the ISP didn't actually route the prefix to you.

                        Have you tried doing traceroutes to see how far IPv6 traffic is getting?

                          I did a packetcapture and got "No prefix available on Link 'de-mhg01a-cr08". This is the router on my ISP. After doing nothing for an hour, the IPv6 came back and everything works.

                          I don't know why this happend the second day in follow, after it worked for months.

                            It's entirely possible that it's an ISP problem, and when it works maybe you luck into pulling a prefix that is actually properly configured upstream. When it doesn't, maybe it's from a block they have not properly configured a few hops away.

                            Maybe keep track of the prefixes that work and the ones that don't, see if there is a difference. Though for an issue this weird, good luck getting an ISP tech on the phone that knows what the heck you're talking about. I do not envy that conversation.

                              I don't know if I remember right, but now under Networking my DUID is set to DUID-LLT. Is that correct for dynamic Prefix via DHCPv6?

                                That's the pfSense default, yes. If your provider requires something different (which would be strange) they need to say so.

                                  Maybe my DUID changed because of some reasons. I was replicating the error right now by setting another DUID. After that no IPv6 appeard on LAN and I got the NoPrefixAvail error. Back to DUID-LLT and it works again after around 15 minutes trying to assign an IPv6.

                                  How can I set the DUID for my WAN interface static?

                                  That's my setup right now:

                                  alt text
