Every online multiplayer session on the Nintendo Switch hinges on one critical factor: NAT type. That three-letter code—Open, Moderate, or Strict—determines whether your connection can seamlessly interact with servers, friends, or rivals. Players who’ve spent hours debugging lag or connection errors know the frustration of being locked into a "Strict" NAT setting, where firewalls and ISP restrictions act as silent barriers. The difference between a smooth online experience and a series of error codes (like E_8015 or E_8013) often boils down to whether you’ve properly configured how to change NAT type on switch. Yet, despite its importance, this process remains shrouded in ambiguity for many users.
The problem isn’t just technical—it’s systemic. Nintendo’s official documentation glosses over the nuances of NAT configuration, leaving gamers to piece together solutions from fragmented forum posts and outdated guides. ISPs, routers, and even the Switch’s firmware interact in ways that aren’t always intuitive. For instance, a "Moderate" NAT type might suffice for casual play, but competitive titles like Splatoon 3 or Fortnite demand the lowest possible latency, achievable only through a properly optimized Open NAT setup. The irony? Most players don’t realize they’re sabotaging their own performance by ignoring this foundational step.
What if you could bypass these limitations without advanced networking knowledge? What if a few precise adjustments—hidden in plain sight—could transform your Switch’s online capabilities? The answer lies in understanding the interplay between your router’s UPnP settings, port forwarding, and the Switch’s internal NAT detection. This isn’t just about changing a setting; it’s about rewiring your home network to work with the Switch’s constraints, not against them. Below, we dissect the entire process: from the historical evolution of NAT types to the future of gaming networks.
The Complete Overview of How to Change NAT Type on Switch
The Nintendo Switch’s NAT type isn’t a static label—it’s a dynamic reflection of your network’s configuration. When you check your NAT type via the Switch’s online test (Settings > Internet > Test Connection), the system evaluates how your router handles incoming and outgoing traffic. A "Strict" NAT means your router blocks most incoming connections unless explicitly allowed, while an "Open" NAT implies minimal restrictions. The goal of how to change NAT type on switch is to align your network’s behavior with the Switch’s requirements, ensuring seamless communication with Nintendo’s servers and peer-to-peer connections.
However, the process isn’t as simple as toggling a switch in the console’s settings. It requires a multi-step approach: configuring your router’s UPnP (Universal Plug and Play) settings, manually forwarding ports if necessary, and sometimes even adjusting firewall rules on your modem. The complexity arises because ISPs and router manufacturers implement these features differently. For example, a TP-Link Archer router might handle UPnP differently than a Netgear Nighthawk, and some ISPs (like AT&T or Verizon) impose additional restrictions that override your router’s settings. This variability is why generic guides often fail—what works for one user might leave another stuck with a "Moderate" NAT when they need "Open."
Historical Background and Evolution
The concept of NAT (Network Address Translation) emerged in the late 1990s as a solution to the impending exhaustion of IPv4 addresses. By allowing multiple devices to share a single public IP, NAT became a cornerstone of home networking. However, its role in gaming was initially an afterthought. Early consoles like the Xbox and PlayStation 2 relied on direct IP connections, but as broadband became ubiquitous, NAT introduced a new layer of complexity. Gamers soon discovered that NAT types could make or break their online experiences—Strict NAT led to connection issues, while Open NAT provided the lowest latency.
Nintendo’s approach to NAT has evolved alongside the Switch’s hardware iterations. The original 2017 Switch used a simplified NAT detection system, often defaulting to Moderate or Strict due to router misconfigurations. With the 2021 revision (Switch OLED), Nintendo introduced minor optimizations, but the core issue remained: users were left to decipher their router’s manuals or rely on third-party tools. The rise of cloud gaming and cross-platform play further complicated matters, as services like Xbox Cloud Gaming or PlayStation Plus require specific NAT configurations to function alongside the Switch. Today, understanding how to change NAT type on switch is less about Nintendo’s limitations and more about mastering the interplay between consumer-grade hardware and gaming-specific network demands.
Core Mechanisms: How It Works
At its core, NAT type detection works by measuring how your router responds to incoming connection requests from the Switch. When you run the online test, the Switch sends packets to Nintendo’s servers and observes the response. If the router allows these packets to return without modification, the NAT type is classified as Open. If the router alters the packets (e.g., by changing port numbers), it’s Moderate. If the router blocks all unsolicited incoming traffic, it’s Strict. The key variables in this process are UPnP, port forwarding, and DMZ settings.
UPnP (Universal Plug and Play) is the most critical component. When enabled, UPnP automatically configures your router to forward ports for devices like the Switch, dynamically adjusting as needed. However, many ISPs disable UPnP by default due to security concerns, forcing users to manually forward ports (e.g., UDP 80, 443, 500, and 3078–3080). The challenge lies in identifying which ports are necessary—Nintendo’s documentation lists over 20 ports, but not all are required for every game. For instance, Animal Crossing: New Horizons may only need a subset of these ports compared to Mario Kart 8 Deluxe’s online races. This granularity is why blindly forwarding all ports can sometimes backfire, leading to connection timeouts or even security vulnerabilities.
Key Benefits and Crucial Impact
Optimizing your Switch’s NAT type isn’t just about fixing connection errors—it’s about unlocking performance tiers most players never realize they’re missing. A properly configured Open NAT can reduce ping by up to 30%, eliminate random disconnections during online battles, and even enable features like party chat in titles that require direct peer-to-peer connections. For competitive gamers, the difference between a Moderate and Open NAT can mean the gap between winning and losing in split-second decisions. Even for casual players, the stability gained from resolving NAT-related issues translates to fewer interruptions during multiplayer sessions with friends.
The broader impact extends beyond individual gaming sessions. A well-configured network also future-proofs your setup for emerging trends like cloud gaming, VR integration, and cross-platform play. As Nintendo continues to push the Switch into new territories—such as its partnership with Microsoft for cloud services—having an Open NAT ensures compatibility with these evolving ecosystems. The investment in learning how to change NAT type on switch today could save hours of frustration tomorrow when new features roll out.

Future Trends and Innovations
The future of NAT configuration in gaming is moving toward automation and AI-driven optimization. Companies like Netgear and ASUS are already integrating "Game Optimizer" features into their routers, which automatically adjust settings for specific titles. For the Switch, this could mean firmware updates that dynamically detect and optimize NAT types based on the game being played. Additionally, as IPv6 adoption grows, NAT’s role may diminish—since IPv6 eliminates the need for address translation, peer-to-peer connections could become seamless without manual intervention.
On the hardware side, Nintendo’s next-gen console (rumored to be codenamed "Nintendo Switch 2") may incorporate dedicated networking chips designed to simplify NAT configuration. Early leaks suggest a focus on reducing latency through hardware-level optimizations, potentially rendering traditional NAT troubleshooting obsolete. Until then, users will continue relying on manual methods to change NAT type on switch, but the landscape is shifting toward smarter, self-adjusting networks that prioritize gaming performance by default.
Conclusion
Changing your Switch’s NAT type isn’t just a technical exercise—it’s a gateway to unlocking the full potential of online gaming on the console. The process demands patience, attention to detail, and a willingness to engage with your router’s settings, but the rewards are undeniable: fewer errors, lower latency, and a more stable connection with friends and rivals alike. The key takeaway? Don’t treat NAT type as an afterthought. Treat it as the foundation upon which every online session is built.
As you implement these changes, remember that no two networks are identical. What works for one user might not for another, which is why testing and iteration are critical. Start with UPnP, move to port forwarding if needed, and don’t hesitate to contact your ISP if your NAT type remains stubbornly Strict. The goal isn’t just to change a setting—it’s to transform your home network into an environment where the Switch can thrive. And in a world where milliseconds can decide victories, that’s a transformation worth pursuing.
Comprehensive FAQs
Q: My Switch still shows Strict NAT after enabling UPnP. What now?
A: If UPnP is enabled but your NAT type remains Strict, your ISP may be blocking UPnP traffic. Try manually forwarding the required ports (UDP 80, 443, 500, 3078–3080) and check if your modem has a separate firewall that needs adjustment. Some ISPs, like AT&T or Verizon, require contacting support to whitelist gaming traffic.
Q: Can I use a DMZ to change my Switch’s NAT type?
A: Yes, placing your Switch in the DMZ (Demilitarized Zone) forwards all incoming traffic to it, often resulting in an Open NAT. However, this is a security risk—any device on your network could be exposed. Only use DMZ as a last resort and ensure your Switch’s firewall is enabled.
Q: Why does my NAT type fluctuate between Moderate and Strict?
A: Fluctuations typically occur due to ISP throttling or dynamic IP changes. If your ISP uses CGNAT (Carrier-Grade NAT), you may never achieve Open NAT. In such cases, focus on optimizing Moderate NAT by ensuring no other devices are hogging bandwidth and that your router’s QoS settings prioritize gaming traffic.
Q: Do I need to forward ports for every game on my Switch?
A: No. Nintendo’s online services use a standardized set of ports, but some third-party games (e.g., Fortnite on Switch) may require additional ports. Always check the game’s official support page or community guides for specific requirements. Over-forwarding ports can create security vulnerabilities.
Q: What if my router doesn’t support UPnP?
A: If your router lacks UPnP support (common in older models or business-grade routers), you’ll need to manually forward ports. Use the Switch’s MAC address to create a static DHCP lease in your router settings, then forward the necessary UDP ports. Some advanced routers allow "port triggering" as an alternative.
Q: Will changing my NAT type void my warranty or violate ISP terms?
A: No, modifying NAT settings does not void warranties. However, some ISPs prohibit port forwarding or DMZ usage in their terms of service. If you’re unsure, check your ISP’s acceptable use policy—most allow gaming optimizations as long as you don’t host servers or engage in illegal activities.
Q: How often should I retest my NAT type?
A: Retest your NAT type after any router firmware update, ISP changes, or if you experience sudden connection issues. Some ISPs dynamically adjust NAT settings, so periodic checks (e.g., monthly) ensure consistency. If your NAT type degrades, re-enable UPnP or reapply port forwarding.
Q: Can a VPN improve my Switch’s NAT type?
A: Generally, no. VPNs often worsen NAT types by adding another layer of encryption and routing, which can introduce latency. However, if your ISP is the root cause (e.g., CGNAT), switching to a VPN that supports port forwarding might help—but this is rare and not recommended for most users.
Q: What’s the fastest way to check if my NAT type is causing issues?
A: Run the Switch’s online test (Settings > Internet > Test Connection) and note your NAT type. Then, play a multiplayer game with a friend. If you experience frequent disconnections, high ping, or error codes (E_8015, E_8013), your NAT type is likely the culprit. Compare your results with friends who have Open NAT to isolate the problem.
