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)

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