      @JKnott said in Configure IPv6:

      Try capturing the DHCPv6 sequence to see what's happening. Post the capture file here.

      Here : https://forum.netgate.com/topic/172514/capture-full-dhcp-or-dhcpv6-sequence?_=1702908820445

      ?

      Or can you show what the dhcp6c process (DHCP IPv6 WAN client) showed you :
      ( First goto System > Advanced > Networking and check DHCP6 Debug )
      Read from bottom to top :

      You can see that dhp6c received a PD :

      IA_PD prefix: 2a01:cb19:907:beef::/64 pltime=600 vltime=7039080927149950728

      Your ISP should have an IPv6 for you, which could be an entire /64, so your WAN interface gets one, a /128), and it should also give you another /64, the PD (see logs above).
      That's the one you can use for your LAN, which has been set up with IPv6 tracking

      My ISP announces IPv6 capabilities like this :

      74ee34aa-08c5-4423-a388-8eded56e000a-image.png

      The first line is the IPv6 address my WAN obtained.
      The second line is the range of prefixes variables : 256 PD's, each one is a /64.

      No "help me" PM's please. Use the forum, the community will thank you.
      Edit : and where are the logs ??

        @JKnott They provide /64. Tried to set up. Traceroute6 google.com is ok but not on LAN side.

        Do you get a valid IPv6 address on the LAN side?

        As @Gertjan mentioned, you may have a /128 on the WAN interface, though it's not necessary.

        I'd beyond belief that some ISPs provide only a single /64. As I mentioned, mine provides a /56 and some a /48. The IPv6 address space is so huge that there are over 4000 /48s available for every person on earth.

              That explains why you can't traceroute to Google. You do not have global IPv6 addresses on your LAN. Your ISP is giving you a single /64, which goes to pfSense, leaving nothing for the LAN side. While my WAN port has an address, it's from a completely different prefix than what I'm assigned via DHCPv6-PD.

              Complain to your ISP for them being so damn cheap with addresses.

                @JKnott I asked him about /56 prefix so they told me that it is not possible to provide. My discount will be off till 2 months so it will be better to change ISP. I found some good. Any way, thanks a lot for help!!!

                  One simple call to 'whoever' allocates / distributes these /32 IPv6 networks (or even smaller) and your ISP has them avaible.
                  Bit this isn't the issue. I'm pretty sure they already 'have them'.

                  The thing is : they have to invest. Their equipment is probably a collection of 'works fine for IPv4' but can not deal with allocating IPv6 stuff, as they can do right now with the IPv4.
                  So they have to invest. But shareholders come first, then the CEOs, then the .... and etc etc.

                  There is only one thing you can do as a client : add the criteria "is this ISP doing the ISP job correctly ?" to your "how to select an ISP" list, and use it you while go out shopping for an ISP. If most clients would do this, all ISPs would be "IPv6 ready", or broke. Suddenly shareholder have lot of decision power ^^

                  Keep in mind the vast majority of all ISP clients don't kw sht about IPv6, or, understandably, don't care. Yet.
                  So up to you to chose wisely.

                    I understand it that you mean but i receive answer that we can provide only /64 at the moment. I think, they do not have client like me or it is cca 5% from total.

                      Initially, my ISP provided only a single /64, but that was temporary and now they provide a /56. However, they still properly used DHCPv6-PD, so that my WAN address was not part of that prefix. It sounds like yours isn't even doing that. In fact, your ISP should be able to provide your prefix via DHCPv6-PD, without having to provide a global address on the WAN. That would at least give you a single /64 to work with. Another possibility is to configure pfSense to be a firewall only and not a router. However, I have no experience with that. Maybe someone else here can advise.

                        The thing is : they have to invest. Their equipment is probably a collection of 'works fine for IPv4' but can not deal with allocating IPv6 stuff
