      Unfortunately the log doesn't show the dhcp6c process.

      Try this.

        Uugh. I need a moment to prepare that setup... I did a packet capture session for now.

        (fe80::aaaa:bbbb:cccc:4b11 is the link local address of the WAN port)

          Please upload the capture file. It contains a lot more info that what you show. When you open it in Wireshark, you can see a lot of detail.

          Here's an example of one I did a few years ago.

            A long time ago that I used wireshark, my old friend.... Please see the capture file attached this post (not much of use in it I guess).

              I thought you had a problem with dhcpv6. There is none of that in the capture. You have to filter on port 546 or 547 to capture dhcpv6.

                I unfortunately haven't got the slightest idea what to investigate. Mybe its DHCP, maybe its something else... So far, I went through anything, tryed any combination on the WAN interface settings, googled (people with the same setup/ provider habe a working environment with the settings stated in the initial post) - I even checked the cables and switches.

                I just don't get any traffic on IPv6 on the WAN-side. LAN-side works well and I can reach the LAN side of pfsense by its (LAN-)IPv6 address.

                What I see, is that any traffic is blocked by a default rule

                Default deny rule IPv6
                

                and a pending gateway

                @syhm was asking for dhcp6c log entries, which I have found eventualy under "general".
                Its as below and only just this repeating.

                Aug 9 22:46:15	php	420	rc.bootup: Unbound start waiting on dhcp6c.
                Aug 9 22:46:16	php	420	rc.bootup: Unbound start waiting on dhcp6c.
                Aug 9 22:46:17	php	420	rc.bootup: Unbound start waiting on dhcp6c.
                Aug 9 22:46:18	php	420	rc.bootup: Unbound start waiting on dhcp6c.
                

                However, the interfaces seem to be.. well... there

                  Start by providing the dhcpv6 capture file as I have now requested a couple of times. Here again are the instructions.

                    Roger that.
                    There isn't actually any thing more than what was captured in the attached file above. There is just nothing related to IPv6 coming on that WAN port.

                    I'll connect a laptop directly to the switch but need to organize an ethernet dongle first and reconfigure the switch (the only non-company-locked laptop I have at hand has a USB C port only).

                    I'll report back. Takes a moment.

                      There is a lot more in a capture file than what you have provided. That's why I keep asking for it. To fully see what's happening, you examine the actual capture file with Wireshark. This will provide a lot more info than you have.

                        Here's an example of what I'm looking for in the captures. This is just part of one packet of 8.
