Why Open Ports for Call of Duty?
Opening ports can significantly enhance your online experience in Call of Duty by ensuring smoother connectivity, faster matchmaking, and reduced lag. Windows Firewall or router settings may block essential ports required for the game to communicate with its servers.

TCP Ports:
- 3074, 27014-27050
UDP Ports:
- 3074, 3478, 4379-4380, 27000-27031, 27036
Always check the official Activision or game-specific site for the most current port requirements.

Windows + R

- Select Port, then click Next.
- Choose TCP or UDP, and enter the required port numbers.
- Select Allow the Connection, then click Next.

3: Port Forward on Your Router

). - Log in with your router credentials.
- Find the Port Forwarding section.
- Add a new rule using your PC’s local IP address and required ports.

4: Verify Ports Are Open
To start, you can use websites like canyouseeme.org or software such as PortQry to confirm whether the necessary ports are open. After that, you can test connectivity by launching Call of Duty multiplayer or Warzone to see if the connection works as expected. For instance, if the ports are open and the game still fails to connect, the issue might lie elsewhere. Therefore, checking both the ports and the game’s performance provides a clearer picture. Additionally, if you encounter persistent problems, you might need to explore further troubleshooting steps. In summary, these methods should help you determine if your connection is functioning properly.
