iptables rules for hosting a LAN world

Apparently, you need to accept traffic on:

  • the TCP port minecraft randomly picks after you open your world to LAN, or your friends won't be able to join;
  • UDP port 4445, or the game will hang when you save and exit from the world.

I tested this repeatedly and indeed it is true for me. If anyone confirms this, we can add it to the wiki. --Alexpin (talk) 17:49, 25 February 2017 (UTC)Reply[reply]

I am aware this was posted 5 years ago but I would like to address an issue with this.
As the port decided by Minecraft is random, probably designed that way to prevent people using LAN's as dedicated servers.
The port which is sent in chat when you start a LAN needs to be opened every single time you open a world up to LAN.

Minecraft wayland should work now

According to it should work now and I am running it without the GDK_BACKEND=x11 hack.

Flatpak setup details

These are the instructions to install the Minecraft launcher using Flatpak and have Gnome-Keyring function properly as well as additionally supporting the .minecraft directory of current user. Install as per

Command line instructions:

flatpak install flathub com.mojang.Minecraft

Next add the necessary filesystem overrides for Gnome-Keyring and optional .minecraft directory.

flatpak override --user com.mojang.Minecraft --filesystem=/home/$(whoami)/.gnupg
flatpak override --user com.mojang.Minecraft --filesystem=/home/$(whoami)/.minecraft

Finally run minecraft launcher.

flatpak run com.mojang.Minecraft

Do we need a guide to how to run Minecraft as a flatpak?
AUR packages already provide the game and servers (and relating software, like panels such as Pufferpanel), if flatpak is needed surely the official site for flatpak has a guide on how to use the Minecraft flatpak?
As this is not specifically Arch Linux content, I am unsure whether this should be included, maybe a maintainer or administrator might be able to explain if this should be added.
