      I don’t have a managed switch now. So I can’t get a sniffer to see what’s going on there. I bought one and I’ll do it as soon as it arrives.

      My ISP is called Vivo. I live in Brazil.

      It provides a / 64 prefix this is the IADP 2804:431:c7d4:788e::/64
      The modem has a DHCP6 PD stateless enable and also RADVD enable with ULA prefix disable.

        Do they only provide a single /64, as some do? Or do they also provide a larger prefix for the LAN side. With my ISP, I get a /56, but if I used their modem in gateway mode, I'd only get a single /64. Also, when they first started providing native IPv6, they only provided a single /64, even in bridge mode. So, what does your ISP provide?

        Also, you can try the instructions I provided to see if you can get the DHCPv6 capture with Packet Capture.

          Here the information I have on the ISP MODEM

          IANA 2804:0431:d78a:5e23:c4d9:9896:XXXX:XXXX/64
          IAPD 2804:431:c7d5:120c::/64

          Then it has a delegated LAN IPv6 info 2804:431:c7d5:120c:1272:23ff:XXXX:XXXX/64

          These are the captures from the WAN and LAN interface.

            I only see one DHCPv6 packet on the WAN side and it appears to be a solicit. What I'd like to see is the response. Also, what size prefix are you requesting in pfSense?

              I don't know why just one. I'll leave it capturing for a longer period let's see if something shows up.

              I have WAN set up as showed below

              The LAN is Tracking WAN.

              Should I use something smaller than 64 ?

                This is a capture of 10 minutes.

                Only soliciting, no replies.

                packetcapture wan.cap

                There are IPV6 blocked by the FW at the LAN side

                It seems a DNS query, not sure if it relates or not to the problem

                    Start Packet Capture, filtering on DHCPv6 on WAN. Then pull the WAN cable and plug it back in. That should cause DHCP to kick in. As I mentioned last week, DHCP only occurs at long intervals, depending on the lease time.

                      Ok. Just did it. I didn't see replies

                      maybe I'm wrong

                        Here's another one. I started the capture, disabled DHCP6 on the wan interface. Applied the change, went back to the dashboard and could see that there was not IPv6. Went back to the interface and enabled DHCP6, applied the change. At the dashboard it has an IPv6.

                        This is the capture of it

                          In your WAN captures, I'm only seeing the Solicits from pfSense, but nothing coming back. The ISP should be responding.

                          Here's what a normal 4 step DHCPv6 process looks like. It has solicit, advertise, request and reply steps. You only have the solicit. You should be getting an advertise next.

                            I know.

                            It's driving me crazy. I tried again to disable DHCP6.When I went on the dashboard the IPv6 of the WAN continued there.

                            I disabled the interface, enabled it again without enabling DHCP6 and it stayed with an IPv6.

                            The only way to get rid of it was to reboot the pfsense.

                            Any new idea ?

                            I have another problem that this HW is not working as PPOE. I read something about an issue with APIC that causes the PPOE not to work. I'm thinking if there is something related to it too on the IPv6 side.

                              Not really. All I can suggest is to try reconfiguring pfSense from scratch. After so much, it's hard to say what you might have done. Does your ISP provide any info or support?
