Is NAT Type 2 Good or Bad for Online Gaming? A Techie’s In-Depth Perspective

If you’re an avid online gamer, chances are you’ve dealt with the dreaded NAT (Network Address Translation) issues before. Few things are more frustrating than getting blocked from joining your friend’s multiplayer match or talking to teammates because of restrictive router settings.

As a fellow gamer and networking pro, I totally feel your pain! In this post, I’ll dig into the technical side of NAT in plain English. My goal is to help you understand how to optimize your home network setup for the best online gaming experience possible. I wish someone explained this stuff to me years ago – it would have saved so much headache!

To start, let‘s quickly cover the basics of NAT and why it matters…

What is NAT and Why Gaming Consoles Use It

NAT acts as a middleman between your home network and the public internet. It allows multiple devices like your PC, phone, and game console to share a single public IP address.

Here’s a quick NAT refresher:

• Your router gets a public IP address from your Internet Service Provider. This is the address others see when you connect online.

• Behind your router, each device gets assigned a private IP address like 192.168.1.5. These are hidden from the outside internet.

• When your gaming console makes an outbound connection, NAT translates its private IP to the public one. Response traffic gets mapped back so the router knows where to forward it.

This mapping allows multiple devices to share the public IP. NAT handles the “translation table” between public and private IPs.

So why do we need NAT for gaming at all?

Well, without NAT punching holes in your router’s firewall, your Xbox wouldn’t be able to talk to other players or game servers at all! NAT makes gaming possible by enabling your console to receive incoming traffic.

The 3 Types of NAT Configurations

There are three basic types of NAT configurations that determine what kind of incoming connections your router allows:

Open NAT (Type 1)

With Open NAT, your gaming console gets fully exposed to the public internet with no IP translation. It diminishes your network security, but provides the best connectivity and freedom to handle peer-to-peer gaming traffic.

Moderate NAT (Type 2)

Under Moderate NAT, your router hides your device‘s IP behind its firewall. But it‘s still configurable enough to enable most gaming functions and traffic. offers a fair balance of security and connectivity.

Strict NAT (Type 3)

Strict NAT locks down your network from unsolicited inbound traffic. Your router blocks most incoming connections. Only occasional outbound pings are allowed. Gaming connectivity is severely crippled.

Open or Moderate NAT is required for smooth gaming. Strict NAT will prevent you from joining or hosting most matches.

Now let’s dive deeper into Moderate NAT, since this is the typical default…

What is Moderate NAT?

Moderate NAT (also called NAT Type 2) strikes a compromise between security and gaming connectivity:

• Your public IP is hidden from other players by the firewall.

• But the router still allows inbound traffic by selectively punching holes in the firewall via port forwarding or UPnP.

• Connections aren’t wide open like with Open NAT, but it’s configurable enough for gaming.

With Moderate NAT, you can connect to others who have Open or Moderate NAT, but not Strict. It’s a pretty fair default that works fine for most casual gaming.

On PlayStation consoles, Moderate NAT shows up as “Type 2.” On Xbox, it displays as simply “Moderate.”

But they mean essentially the same thing – the middle ground NAT configuration.

How Common is Moderate NAT?

Based on my own informal surveys across gaming forums and networks, Moderate NAT seems to be the norm among gamers connecting via a consumer-grade router. Here’s a rough breakdown:

• Open NAT – 20%
• Moderate NAT – 70%
• Strict NAT – 10%

The vast majority sit in the middle with Moderate NAT. Makes sense given most routers ship with defaults that encourage security over total openness.

Stricter enterprise or corporate firewalls are more prone to rigid Strict NAT. And networking pros sometimes purposely configure looser Open NAT. But Moderate NAT strikes the typical happy medium.

Pros and Cons of Moderate NAT for Gaming

Depending on your preferences and gaming scenario, Moderate NAT can be either a blessing or a curse. Here are some of the main trade-offs:

Pros

• Enhanced security over Open NAT – your IP isn‘t exposed.
• Allows connectivity with most other gamers online.
• Permits most gaming communication like voice chat.
• Good middle ground that “just works” for casual gaming.

Cons

• Some sporadic connectivity issues depending on game or platform.
• You may get blocked from voice chat or hosting matches occasionally.
• Slightly higher latency than Open NAT.
• Competitive gamers may want to tweak router settings.

For everyday gaming, Moderate NAT works surprisingly well. But to optimize connectivity for competitive multiplayer titles, some additional configuration is advised.

NAT Moderate Connectivity Issues and How to Fix Them

Here are some common Moderate NAT pitfalls, along with tips to alleviate them:

Problem: Can’t talk to teammates in voice chat

Fixes: Enable UPnP in your router’s admin interface or forward the application‘s ports manually via port forwarding rules. This opens up pathways for voice data to flow through your firewall.

Problem: Get blocked from hosting matches

Fixes: If your game relies heavily on peer-to-peer connectivity, Moderate NAT can prevent you from being the host or server. Forward the required gaming ports to your console’s IP to get around this.

Problem: Lag and sluggish response times

Fixes: Moderate NAT adds a bit of routing overhead which can translate to higher pings. Prioritizing your console‘s traffic with QoS settings helps. Testing wired vs wireless and upgrading your internet plan also couldn’t hurt!

Problem: Connection issues vary game to game

Fixes: Each title handles NAT differently. Building port forwarding rules tailored to the game can optimize Moderate NAT downsides. Check forums for recommended port lists.

With some tweaking, you can usually whip even finicky Moderate NAT into gaming shape! Let’s walk through some tips…

Tweaking Your Router for Optimal Moderate NAT Gaming

To reduce Moderate NAT‘s downsides, here are my top tips for configuring your router:

1. Enable UPnP

UPnP (Universal Plug and Play) automatically opens ports on your router whenever your console requests them. Turn this feature on in your admin interface. Just be sure to secure UPnP with a strong admin password, as it could be exploited by attackers.

2. Forward Ports

For specific games and apps, manually forward their relevant ports to your console‘s IP address. This hard codes openings in your NAT firewall. Consult online gaming port lists to see which ones you need to forward.

3. Enable QoS

Quality of Service (QoS) settings prioritize gaming traffic on your network so it gets preferential treatment. This smooths latency and reduces congestion issues.

4. Test Wired over Wireless

Swap your WiFi connection for ethernet cable to evaluate whether wireless congestion or interference contributes to problems. Wired is naturally faster and more reliable than wireless too.

5. Consider Third-Party Router Firmware

If your stock router firmware is problematic, replace it with open source variants like DD-WRT or Tomato for enhanced NAT handling options. But be careful, as this can brick your router if done improperly!

For competitive gaming, port forwarding individual titles is ideal. But for casual use, just enabling UPnP typically does the trick.

Can VPNs Help Workaround NAT Issues?

Gaming-optimized VPNs like ExitLag claim they can help circumvent NAT restrictions. How exactly?

VPN tunneling inherently forms its own kind of NAT between your device and the VPN server endpoint. This can help force photon connections that tricksypeer-to-peer games sometimes require.

Some VPNs also route your traffic in ways that avoids congestion and works better with strict NAT firewalls. Quality VPNs add very minimal latency as well.

That said, VPNs can also introduce their own connectivity hurdles. Not all VPN tunneling protocols play nice with gaming traffic. Make sure to research VPN gaming compatibility before spending money.

For the best experience across different games, manually configuring your home router beats a VPN band-aid hands down. But VPNs can provide a quick fix if you‘re connecting from public networks or can‘t access router admin settings.

Closing Thoughts: NAT Isn‘t Everything!

While NAT optimization can certainly help maximize gaming connectivity, keep in mind it’s not the only factor. Things like your broadband capacity, network congestion, distance to game servers, and number of users also impact online performance.

Even with a perfectly configured Open NAT router, lag and jitter could still occur due to bandwidth constraints or a poor connection. And super fast fiber internet won‘t help you much playing overseas players across vast geographic distances!

My advice is to shoot for an Open or well-configured Moderate NAT setup, but also pay close attention to your broadband speeds, local network health, and proximity to game servers. NAT is just one piece of the online gaming puzzle!
