Player Authentication​

  • If you are using SteamCore PRO 1.0.3.1 and newer you can automatically authenticate players on your dedicated server by using the new SteamCore Auth Module.

Use IP Connection on Dedicated Server​

  • Requires SteamCore PRO 1.0.3.2 and newer
  • By default the traffic between client and server will use the P2P relay network and route the traffic through steam, if you want to use the old traditional way of connecting via IP you can disable the bAllowP2PPacketRelay setting in your DefaultEngine.ini
[OnlineSubsystemSteamCore]
bAllowP2PPacketRelay=False
