Firewalls must permit connections to take place. Both games must be at the same version.

Port forwarding (or DMZ) is not required as a LAN does not require routing I'm going to jump in to make sure you don't get too side-tracked. Now, open Warcraft 3 on both machines, Create a LAN game from one machine, and check the other machine to see your newly created game available for selection. Of course the second method is easier, but it works best on 10.5.8 or higher. or b)Click "Browse" and you will see the other computer available for selection, along with any other machine that can be shared. In there, you have 2 options: a)Enter the exact address of the other computer as it is shown on System Preferences on File Sharing. That will give you each computer's LAN address.Ģ)Connect the 2 computers using one of the 2 ways: Go to the finder, and On the Go menu, select the "Connect To Serve option. Open System Preferences->Sharing and check the "File Sharing" option. You will also need to establish the connection from the Finder.ġ)Make sure file sharing is turned on in both computers. Physically connecting to the other mac using Ethernet or WiFi is not sufficient. You don't mention if you have connected one mac to another. I have managed to play on LAN with 4 computers using only one CD key. However, I must add that in order to play LAN you don't need to have legitimate keys. I assume that you have a total of 4 different legitimate CD-Keys: 2 keys for Warcraft 3 and the expansion on one machine, and 2 keys for warcraft 3 and the expansion on another.
