Minecraft Education | Unable to join multiplayer game

Thanks for the response. Yes! bitdefender firewall on the PC has and was disabled.
UPDATE: others can join when my child hosts the multiplayer game/world but they still cannot join their classmates/teachers worlds/multiplayer game.
But the same players/teacher can join each other’s without issue.

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?

Welcome to hell, my friend. We are approaching our four year anniversary of this issue, join me in celebrating the eternal life of Feature #7727: https://redmine.pfsense.org/issues/7727

Hello, by any chance are you using a Apple device with private addresses enabled in the Wi-Fi?
-
@daddygo no mention of UPNP.
-
@uglybrian no it’s windows 10 dell inspiron laptop it uses private subnet 192.168.40.x they all do. Wi-Fi is provided by unifi AP.

@bigchimpin hey I remember seeing this bug!
Lol it’s been hell last two days. Was considering shelling $799 to netgate support.... -

as the colleague @bigchimpin mentions, we have already discussed it here:
(wait - wait and end up waiting)

BTW:
so I asked about UPnP
-
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 interfaceThen under
UPnP Access Control Lists allow 53-65535 192.168.40.99 53-65535Unfortunately 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.

This will not be resolved today, maybe tomorrow
-
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.
-
@posix said in Minecraft Education | Unable to join multiplayer game:
making changes Services UPnP & NAT-PMP.
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.
