  Done!
Now you've setup Warcraft 3. Next you need
  to setup a virtual LAN
  Setting up a Virtual Lan
In this section I'll show
  a guide for setting up ZeroTier.
  Before you continue
Only one person
  needs to setup a network. Everyon else can join an existing
  network through the network's creator (admin). And once
  you've been authorized by the admin you can join/unjoin as you please.
  The admin doesn't even need to be in the same game / online.
  Admin | Network Setup
If you want to be the network admin you can
  create a network by first creating an account with ZeroTier. You'll need
  to supply a verifiable email but that is it. Here is a quick summary of how
  to setup. A full guide can be found at 
  Zero Tiers own setup guide
  
    
    Hover to Zoom
   
  Your Network ID
Your network ID will be present on the network page.
  The example netowrk here is: 17d709436c634b2b.
  You will share this with the members.
  Admin | Network Settings
You shouldn't have to do anything
  custom, just authorize the users who join your network. This can be done by
  either adding them directly, or checking the authorize box. You can add them
  from the settings menu at the bottom:
  
    
    Hover to Zoom
   
  Member | Download
Note Admins must also join their own
  network! Member's first must download the application: Zero Tier 1.
  Member | ZeroTier UI
The ZeroTier UI is just a system-tray icon. Just
  right click to perfom any of the actions listed below. (It's the icon
  that shares the icon from the website!)
  
    
    Hover to Zoom
   
  
    
    Hover to Zoom
   You can right click the tray-icon to open the menu. Here you will see
  your Node Id. Example: Node ID: 2d213b67f2
  Member | Add network
To join simply paste the network ID in the form.
  You can get the ID from the Network Admin.
  
    
    Hover to Zoom
   
  Admin | Authorize the Member
The Admin will then need your
  Node ID and will authorize you in their network settings.
  
    
    Hover to Zoom
   
  Member | Reboot
Now that you've connected and setup I recommend
  rebooting here. You can also reboot upon installation too to be safe.
  Member | Verify connectivity
You can open the menu and click
  "Show Network" which will show you your connected networks. You
  should see Status: OK. You can click the connect
  checkbox here to connect/disconnect. Or click the network from the menu
  directly.
  
    
    Hover to Zoom
   
  Admin | Verify everyone is
  connected
You can verify the connected
  nodes by looking at the network view under Members. You should see Last Seen
  "ONLINE" and their Physical IP - this will mean they're
  connected successfully. You can add names and descriptions to help manage who
  is who in case someone loses connectivity.
  Creating a LAN Game
At this point you should be able to create a LAN game. It will
  ask you to install Bonjour services. Click yes. The game may hang for a bit
  while this happens, that is normal. Authorize the network firewall popup if
  it does.
  Troubleshooting
The network Admin can troubleshoot any connectivity issues by
  checking if the Member's are present in their network settings.
  Status:
  Request_Configuration
If you are stuck
  in this status you can delete the network. Reboot. Then re-add the network
  and have the admin re-authorize you if necessary. This may take a few minutes
  before you're IP appears in the network settings for the admin.
