> to make outbound connections to the internet (or more specifically to the Mojang auth server) I believe you can forgo even that; a vanilla server jar can be configured to run in "cracked" mode by setting 'online-mode' to false in server.properties. Skins won't work though, players will have steve/alex skins. It's documented on the no-longer-official wiki here: > online-mode - Server checks connecting players against Minecraft account database. Set this to false only if the player's server is not connected to the Internet. Hackers with fake accounts can connect if this is set to false! If minecraft.net is down or inaccessible, no players can connect if this is set to true. Setting this variable to off purposely is called "cracking" a server, and servers that are present with online mode off are called "cracked" servers, allowing players with unlicensed copies of Minecraft to join. https://minecraft.fandom.com/wiki/Server.properties https://minecraft.fandom.com/wiki/Server.properties
