How to Change NAT Type on BO3 PC Complete Network Setup Guide
Navigating multiplayer lobbies in Call of Duty: Black Ops 3 on PC can quickly become frustrating if your network limits your connection options. Players experiencing high latency or lobby joining failures often trace the issue back to a strict or moderate Network Address Translation configuration. Adjusting your system settings to achieve an open status ensures smoother matchmaking and a much more reliable online experience.
Understanding Network Address Translation in Black Ops 3
Network Address Translation manages how incoming internet traffic connects directly to devices inside your home network. In Black Ops 3, your NAT classification dictates which players you can join during online sessions. An open environment allows seamless communication across all connection types, whereas strict or moderate settings block incoming data packets from other players.
When playing on PC, security firewalls or restrictive router profiles can accidentally block the ports required for peer-to-peer connections. Identifying the exact status reported by the game client is the essential first step toward fixing connectivity issues. Once you confirm a restricted connection status, adjusting your local network configurations will resolve the problem effectively.
Configuring Router Settings for Port Forwarding
Port forwarding is the most reliable method for opening your network connection for Call of Duty titles. Access your router administration portal by entering your default gateway address into a standard web browser. Locate the advanced network settings menu where port rules are created and managed.
To establish an open status for the game on PC, forward UDP port 3074 directly to your computer's local IP address. You can also forward TCP ports 27014 through 27050 to ensure steam network services operate without restrictions. Applying these specific rules allows incoming game data to pass through your router firewall cleanly.
Enabling UPnP and Windows Network Discovery
If manual port forwarding seems overly complex, enabling Universal Plug and Play offers an automated alternative. UPnP allows Black Ops 3 to dynamically request open ports whenever the application runs on your PC. You can toggle this feature directly within your router settings under the primary network interface menu.
Additionally, ensuring Windows Network Discovery is active on your PC prevents operating system firewalls from filtering traffic. Check out to optimize your overall system setup and network performance. Combining automated router management with proper Windows sharing settings creates a stable foundation for online gaming.
Verifying Your Connection Status
After adjusting your network parameters, restart both your internet router and your PC to ensure all rule changes take effect. Launch Black Ops 3, navigate to the main menu, and open the network options tab to verify your status. The network menu should now display an Open NAT type alongside the correct port assignment.
Maintaining an open connection significantly improves party joining capabilities and reduces overall lobby queue times. If the game still reports a moderate or strict status, check whether your internet service provider uses Carrier-Grade NAT. Contacting your provider to request a dynamic public IP address will solve any remaining restrictions.
