Synopsis

  • Unreal Engine 2/2.5 game servers commonly use UDP 7787 for server query/uplink beacons; a well-known example is Unreal Tournament 2003/2004, where admins typically open UDP 7777 (game), 7778 (query), and 7787 (uplink/advertising).
  • Other UE2 titles that have used this port in practice include Postal 2: Share The Pain and Red Orchestra: Ostfront 41-45, where community and vendor server setup guides list UDP 7787 among the required open ports for server advertisement/master-server communication.
  • You’ll see UDP 7787 referenced in many legacy Unreal-based dedicated server configurations hosted on Windows or Linux for public server browsing via the old GameSpy ecosystem.
