A patch for vanilla servers to work with BungeeCord's ip_forward setting.
This uses ME1312's fork of VanillaCord which has been updated for modern Minecraft.
If you've set up Spigot, Paper or some other server with BungeeCord's IP forwarding you might know that you have to set online-mode to false. Due to the way that VanillaCord works this is not necessary with this Egg, you can (and should) leave online-mode as true.
