UDP 2303
Synopsis
- Microsoft DirectPlay (used by many classic PC games) commonly uses UDP port 2303 as part of its multiplayer session traffic.
- Examples include Age of Empires II: The Conquerors, Dungeon Siege, MechWarrior 4, and Rise of Nations, which require UDP 2302–2303 (often alongside other DirectPlay ports) for hosting/joining games.
- Halo: Combat Evolved (PC) multiplayer also documents UDP 2302–2303 for hosting servers.
- Bohemia Interactive’s Arma series (Arma 2/Arma 3) uses UDP 2303 as the server’s Steam query/status port by default, with UDP 2302 used for the main game traffic.
- These are real, widely deployed uses; the port is not specifically known for exploitation beyond being a common target for generic UDP floods against game servers.
