Technical Details
what runs on :15567Port 15567 over UDP has been widely adopted by Electronic Arts' Battlefield Vietnam and its associated modifications. It acts as the core communication channel between game clients and dedicated servers, enabling actions like joining matches, transferring game event data, and managing player movements. The choice of UDP allows for rapid, connectionless data exchange where occasional packet loss is acceptable and low latency is prioritized.
This port supports a variety of gameplay mechanics by efficiently relaying status updates, hit notifications, and game world events. Mods often leverage this same port, extending the core game's communication protocol or layering additional content and rules. Its usage is mostly limited to Battlefield Vietnam, reducing interference with other services but requiring explicit configuration in firewalls and NAT scenarios.
From an infrastructure perspective, port 15567 typically requires port forwarding on routers for home-hosted servers and caveats around Internet playability, ensuring players can discover and join custom or official game servers reliably. The port does not typically carry encrypted data and interacts at the application level with the game's proprietary protocol.

security overview
Common vulnerabilities involving this port include:
- Exposure to Distributed Denial of Service (DDoS) attacks targeting open game servers
- Exploits stemming from vulnerabilities in the Battlefield Vietnam server or modded code
- Information disclosure risks due to unencrypted game data, which could enable player data harvesting or manipulation
To mitigate these risks:
- Restrict access using firewall rules allowing only known IP ranges
- Regularly update server software and apply official patches
- Avoid hosting on machines with sensitive data or elevated network privileges
- Use network traffic monitoring to identify suspicious activity
- Where possible, employ rate limiting or anti-DDoS protections to guard against service disruptions
