Local lan server

I believe the same question was asked here: setup-of-pcs-on-lan-game-only-aoe-2-de

TLDR:

  1. Make certain that the two machines are on the same local network (you are both connected to the same router either via wifi or ethernet cable).

  2. Change the firewall settings (on both machines) and allow incoming communication on these ports:
    Try just opening these ports first:
    TCP Port 8888 , Port 3478 (UDP & TCP), Port 5222 (UDP & TCP)
    and if they don’t work, then do all the below:

Age of Empires II: Definitive Edition - PC

  • TCP: 3074,3478,5222
  • UDP: 88,500,3074,3478,3544,4500,5222

Age of Empires II: Definitive Edition - Steam

  • TCP: 3074,3478,5222,27015-27030,27036-27037
  • UDP: 88,500,3074,3478,3544,4380,4500,5222,27000-27031,27036
  1. For some reason, it also appears for some people that both machines have to have a working internet connection in order to play LAN (can’t confirm or deny this)?
