Warcraft 3 LAN Game discovery
How does Warcraft 3 discover games on the LAN?
I have 3 machines, all with Warcraft 3 1.31 (Not Reforged.) A Mac, A Windows 7 PC and a Windows 10 PC. Any of them can host a lan game just fine, but the windows 10 PC cannot find games hosted by the mac or the windows 7 PC. Even if I turn off the firewall.
What ports and protocols does Warcaft 3 use to find lan games? (Hosting games is well known.)
Best Answer
Warcraft 3 sends broadcast packets on UDP port 6112. If the machines aren't on the same subnet, or something is not forwarding broadcast packets, then they won't see the game.

Specifically, when offline, the \u201cCustom Games\u201d button changes to \u201cLocal Area Network\u201d. There's been some confusion about the ability to play LAN games with the new Reforged client. LAN games do exist! Unfortunately though, getting them set up is not as intuitive as it used to be.Does Warcraft 3: Reforged have LAN?

Based on Some Articles I found on the BattleNet forums, it seems like Blizzard has been trying to faze out LAN for awhile now, perhaps starting with 1.30.2 but definitely now with reforged. If LAN has worked before on the current patch you are on, make sure that your computers can see each other. You can do a simple ping check by checking your ip address with ifconfig on your mac and ipconfig on Windows in a terminal/command prompt and then using the ping command with the IP addresses of your other computers. You can also check in your file systems if you have your computers open to each other on your network.
If you were forced into this patch after not playing for awhile, I'd recommend following the first article to get an older version of the game. You may not have upgraded to reforged but they did get rid of the classic client which did remove LAN. It sounds like you still have the option but people mentioned issues finding games and games force closing while on LAN in the second article so an older version may help.
