    Rule for VLAN40 is doing its thing on VLAN50 (?)

      Attached also the firewall rules for that VLAN50; I don't see any 'VLAN40' in here, so no clue why the previous weird picture.

        WAN2 (cable) blocked a private IP, but the destination is weird?

                            And, finally, the LAN rules in two parts (note the number of 'easy rules passed from firewall log view'. And even then they still aren't working, as the log is still flooded with IPv6 as shown in the first picture):

                                And finally, the multicast-alias in the LAN rules:

                                  So I will be feeling hugely indebted to everybody who can help me solve this, that goes without saying  :P

                                  (because it is driving me crazy, this flooding of logs which I am trying to fight with the firewall rules every day  :-[).

                                  Thank you in advance very much (really  :-*),

                                  Bye  ;D

                                    EDIT: I forgot one screenshot from the general system log. Errors 'finding Ipv6 gateway' (?) on both WAN and WAN2 (=opt4).

                                    I should also add that I added this WAN2 a couple of days ago (I don't know exactly when anymore), and I also don't know if that is when the IPv6-flooding in the logs and the error in the attached picture began  :-\

                                          Everyone of those seems to me blocked because of states out of sync you notice the tcp flags on the proto

                                          TCP Flags: F - FIN, S - SYN, A or . - ACK, R - RST, P - PSH, U - URG, E - ECE, W - CWR

                                          https://doc.pfsense.org/index.php/Logs_show_%22blocked%22_for_traffic_from_a_legitimate_connection,_why%3F

                                          This is going to happen when you have something get out of wack where pfsense states do not list these connections and then sees traffic.  Can happen when you clear states or reboot pfsense.  Can happen if you have devices that are in and out of the network, say wireless devices for example.  I mostly see these in my logs from my sons phone.  This sort of thing is common and will happen with any stateful firewall.
