Technical Details
what runs on :2302-
Overview: Port 2302 is the default communication channel for multiplayer modes in the ArmA franchise developed by Bohemia Interactive. It predominantly relies on UDP to achieve fast, low-latency data transmission critical for real-time gameplay synchronization.
-
Functionality: When a player hosts an ArmA game server, port 2302 is utilized for initial client-server handshakes, lobby communication, and in-game data exchange such as player positions, actions, and game events. Additional ports (typically 2303-2305) may also be used for dedicated voice traffic and battleEye anti-cheat integrations, but 2302 remains the primary channel for gameplay.
-
Protocol Details: Since ArmA leverages UDP on this port, the communication is connectionless and optimized for speed rather than reliability. The server sends broadcast packets to maintain session updates, and clients continuously exchange position and status information to ensure a smooth gaming experience.

security overview
-
Common Vulnerabilities:
- Exposure of port 2302 can attract attacks such as UDP amplification, Denial of Service (DoS), or brute-force attempts to exploit vulnerabilities within the ArmA server software itself.
- Poor server configuration may leave administrative interfaces exposed or enable attackers to disrupt multiplayer sessions.
-
Mitigations:
- Employ strict firewall policies to restrict access exclusively to intended players or trusted IP ranges.
- Keep the ArmA server software and any related anti-cheat tools (like BattleEye) updated with the latest security patches.
- Use network monitoring tools to detect and prevent unusual traffic spikes indicative of DoS attacks.
- Consider using DDoS protection services if hosting large-scale or public servers.
