      The config looks good. So…

      You did set:  System: Advanced: Networking: Allow IPv6 ?

      Allowed for WAN IPv6 ICMP I/O ?

        Yes, allow IPv6 is checked and there's a rule to allow ICMP (v4+v6) on the WAN interface.

          Have you tried if it works if you actually use PD (i.e., set IPv6 to "track interface" in the LAN config)? Won't give you the desired static addresses, but maybe a good first step to make sure everything else is in order?

            Also, what's the deal with 4008 vs. 40xx? In your config above, the "xx" will have to be "08" or it won't work for sure.

              Good morning,

              i switched the "IPv6 Configuration Type" to "Track Interface" and rebooted (just to be sure). Now the lan interface has only the link local address but doesn't show any others. Does that mean that the pd doesn't work?

              (and sorry for the xx, it was a feeble attempt to obfuscate the address  :) )

                It would appear so. Anything relevant in the logs?

                  The dhcp log is quite inconspicuous, just the messages regarding the assignment of the ipv4 address, but i found the following lines in the router log:

                  radvd[18174]: IPv6 forwarding setting is: 0, should be 1
                  radvd[18174]: IPv6 forwarding seems to be disabled, but continuing anyway.
                  radvd[18174]: no auto-selected prefix on interface em0, disabling advertisements
                  radvd[18374]: sendmsg: Can't assign requested address

                  erm … ipv6 forwarding seems to be disabled? I checked it again, ipv6 is enabled in the system -> advanced -> network settings. Is there any other checkbox i didn't see?

                    If running LAN all static, then one need  Services: Router advertisements(Router Only)

                    Have DNS-servers override if DHCP-PD to ISP ?

                    How do you request your IP's (IPv4&6) from ISP. Do you have an IPv6 showing in Status: Interfaces ?
                    Is it a public /64 or /128 ? or a local fe80:: ?

                      Yes, "Router Advertisements" is on "Router Only".

                      @hda:

                      Sorry, don't know what you mean. But what impact could dns servers have on such a low level?

                      Straight from the interface status page:
                      IPv6 Link Local    fe80::6a05:caff:fe2e:4dc7
                      IPv6 address      fe80::6a05:caff:fe2e:4dc7
                      Subnet mask IPv6  64
                      Gateway IPv6      fe80::223:33ff:fe74:6e3f

                        Problem solved dance :D

                        i was browsing the forum and found the following in another thread (https://forum.pfsense.org/index.php?topic=65724.15):

                        • I would also uncheck the "Block bogon networks" box on both the WAN and the LAN, as there have been issues with these being overly broad for IPv6 and blocking legitimate (and required) traffic.

                        I unchecked the boxed and voilà:

                        ping6 2a02:168:4008:1::1
                        PING 2a02:168:4008:1::1(2a02:168:4008:1::1) 56 data bytes
                        64 bytes from 2a02:168:4008:1::1: icmp_seq=1 ttl=52 time=26.6 ms
                        64 bytes from 2a02:168:4008:1::1: icmp_seq=2 ttl=52 time=27.3 ms
                        64 bytes from 2a02:168:4008:1::1: icmp_seq=3 ttl=52 time=26.5 ms
                        64 bytes from 2a02:168:4008:1::1: icmp_seq=4 ttl=52 time=26.6 ms
                        64 bytes from 2a02:168:4008:1::1: icmp_seq=5 ttl=52 time=26.5 ms
                        (pinged from an external host)

                        Thank you all for your help and assistance, really appreciate it!
