Welcome to my guide for fixing the multiplayer, this guide will show you how to set up your own Nat Facilitator server so you can play Etherium online with friends using the BugFixesAndQoL mod. Only one person needs to host the facilitator on your network or via ZeroTier.

• Version 1.4.0 of the BugFixesAndQol mod or higher
  
• ZeroTier[www.zerotier.com] (For online multiplayer)

1. Download the Nat Facilitator
   
   • Go to this link: https://github.com/LostGameDev/EtheriumNatFacilitator/releases and click EtheriumNatFacilitator.zip to download it. Make sure to save it somewhere you can find it easily, note do not put it in your plugins folder!
2. Extract the files
   
   • Once downloaded, right click the zip file and click extract.
3. Start the Nat Facilitator
   
   • Once extracted open the newly created folder called 'EtheriumNatFacilitator' and run the file named 'start facilitator.bat'. If a console window that looks like this opens then congratulations you have successfully installed the Nat Facilitator! At this point anyone playing on the same local network should be able to use multiplayer normally
     

To let people connect from outside your local network:

1. Install and launch ZeroTier.
   
2. Create a new network at ZeroTier Central[my.zerotier.com].
   
3. Invite all players to join the same ZeroTier network.
   
4. Everyone (including the host) must approve their clients on the ZeroTier dashboard.
   
5. The host should note their Managed IP from the ZeroTier app. This will be used in the next step.

1. Open the mod config located at:
   
   BepInEx/config/BugFixesAndQoL.cfg
2. Find the NatFacilitatorIP setting under the [Multiplayer] section.
   
3. Change:
   
   NatFacilitatorIP = 127.0.0.1
   To:
   
   NatFacilitatorIP = <Managed IP of the host>
   For example:
   NatFacilitatorIP = 174.46.129.241

1. Launch Etherium with the BugFixesAndQol mod installed.
   
2. Go to Multiplayer and create a new server.
   
3. Everyone connected to the same ZeroTier network should now see your server in the list!

• Make sure Windows Firewall isn't blocking the facilitator (port 50005).
  
• Ensure everyone has joined the same ZeroTier network and is approved.
  
• Confirm the facilitator is still running in the background.
  
• If no server appears, double-check the NatFacilitatorIP is set correctly in the config.
