      others can join when my child hosts the multiplayer game/world

      It sounds like multiplayer is working (port 19132), ergo this is not a pfSense or host FW issue

      -does Minecraft Edu. use UPnP or other ports?

          Hello, by any chance are you using a Apple device with private addresses enabled in the Wi-Fi?

                  as the colleague @bigchimpin mentions, we have already discussed it here:

                  BTW:
                  so I asked about UPnP ๐Ÿ˜‰

                    Ok thanks, so another update I was researching on UPnP and forgot to add the following configuration. (I did this for another gaming PC to get from strict NAT to moderate NAT and I did see better behavior).

                    Services -> UPnP & NAT-PMP (check)
                    Enable UPnP & NAT-PMP (check)
                    UPnP Port Mapping Allow UPnP Port Mapping (check)
                    External Interface WAN
                    Interface SPECIFIC VLAN interface
                    
                    

                    Then under

                    
                    UPnP Access Control Lists
                    allow 53-65535 192.168.40.99 53-65535
                    

                    Unfortunately still not able to join games. Looking at the packet capture I took using (Full) Level detail. I saw many retransmits in TCP. They would come in batches in the flow then everything would return to normal. I googled upnp wire shark capture and it seems all are UDP port 1900 and SSDP.

                    @bigchimpin @DaddyGo I want to thoroughly exhaust my options and go through the steps before calling it.I dont doubt your analysis. Mainly documentation. Perhaps might help others get a workaround in place as I did.

                        UPDATE:

                        My child confirmed today that they are able to join other players world.

                        I can confirm no change in configuration other the last update I provided on
                        making changes Services UPnP & NAT-PMP.

                        Will monitor some more.

                          Which I would like to add, with things like UPnP & NAT-PMP be careful on your firewall.
                          Always run on a separate interface
                          (I see you have a VLAN for this purpose)

                              Did anyone try just port forwarding the recommended ports on the https://portforward.com/minecraft/ page? I'm going to give that a try because I don't really want to turn UPnP on.

                              Some additional ports to forward would be 19133 and 25565 which I didn't see mentioned in this thread.

                                Nevermind, I guess 19133 is for IPv6 and 25565 is for Java Edition. So, opening 19132 should do it for my setup, but I cannot join only host. Minecraft Education gets the wrong IP though.
