        My crystal ball is still on the fritz, so you'll have to provide a bit more info. For example, is your modem in bridge or gateway mode? Do you get a WAN IPv6 address? Maybe you can provide some images of your configuration. Etc..

          1- Do you get a WAN IPv6 address:

          yes I can get the ipv6 address

          2- your modem in bridge or gateway mode

          I connect the pfsense through ethernet cable in the modem and the modem connected to fiber to the ISP

          I will provide some images (DS = LAN)

                  and I am not sure what do you mean if the modem is the gateway or bridge mode

                  but I told you the way how pfsense is connected "I connect the pfsense through ethernet cable in the modem and the modem connected to fiber to the ISP" maybe my modem is gateway mode or bridge mode

                    That depends on the modem. If you post the make & model, someone might be able to help you. Or you could search on the model and bridge mode. You might also ask your ISP to do it.

                    In bridge mode, the modem is essentially transparent and connects pfsense to your ISP. In gateway mode, the modem is also a firewall/router. But that then gets in the way of pfsense obtaining IPv6 for your LAN. Out of the box, ISP provided modems tend to be in gateway mode.

                      my modem model:
                      info router.PNG

                      I have seen that I have something called port mode and I have tried bridge mode but when I do that I got from the wan in pfsense that the IP is 0.0.0.0 instead of the original IP which something like that 192.168.1.18 and also there no connection to the internet when I use bridge mode

                      port mode.PNG

                      maybe the bridge mode for 2 port because the modem have 4 port ethernet-like to connect the first port to second port that's what i think and maybe I am wrong about the port mode

                      and i have use prefix 56 in WAN DHCP6

                      because my prefix in modem is 56
                      ipv6 info router.PNG

                      also, I have found that pfsense has something called bridges in the interfaces is that maybe will help??
                      so is there anyway to like LAN interface bypass the pfsense dhcp and etc.. and get from the modem like ipv4 , ipv6

                        Here's something that may help:
                        Networking mode configurations - DHCP, static, PPoE, bridge

                        I have a Hitron modem that also does phone, so I have no experience with Nokia. Perhaps someone else does.

                          Although, my wifi-router with integrated dsl-modem is capable of prefix delegation in "Gateway"-mode.

                            Do you mean it provides a prefix to a LAN? Or it passes prefixes to pfsense which can then provide them to a LAN?

                              @jknott The latter.

                                That would mean the modem can use DHCPv6-PD, which is unusual. How do you control which prefixs are passed on?

                                  @jknott It is a router for around 100 bucks. It only has one switch and one guest network, so the rest will get passed on I guess.
