This comprehensive guide explains what NAT (Network Address Translation) is and the differences between open, moderate, and strict NAT types. It outlines in detail how to change your gaming console’s NAT type to be more open through router settings like port forwarding, DMZ access, assigning a static IP, and enabling UPnP. Additional tips are provided for changing your NAT type without a router by tweaking console network settings directly. A troubleshooting section covers common problems like firewalls blocking ports and ensuring proper IP addressing. The article also answers frequently asked questions about the security trade-offs of an open NAT. It provides readers a full understanding of NAT fundamentals and how to configure it for optimal gaming experience.

When gaming online, your NAT type plays an important role in connecting to other players. Similarly, when streaming content online, such as using services like Sky Go, ensuring a smooth connection is essential. Discover how you can enjoy unrestricted access to Sky Go from any location by reading about how to watch sky go from anywhere. NAT (Network Address Translation) helps manage the flow of traffic between your home network and the internet. Using a vpn for gaming can further enhance your gaming experience by stabilizing your connection and reducing lag.

Depending on your network setup, your NAT type may be strict or moderate, which can cause issues like slow connectivity, lag, and difficulty joining games. In many cases, you’ll ideally want to change to an open NAT type for the best online gaming experience.

The main ways to change your NAT type are through router settings like port forwarding, adjusting console network settings, or contacting your ISP. This guide will walk through how to modify your NAT type using these methods to improve gaming connectivity.

What is a NAT Type?

NAT manages how devices on your home network, like your gaming console, interact with the wider internet. Here’s an overview of how it works:

  • NAT maps the IP addresses of devices on your local network to a single public IP address on the internet. This allows multiple devices to share a connection.
  • It does this by assigning local private IP addresses to each device (like and then translating requests to the public IP.
  • This translation means your network devices aren’t directly exposed to the public internet.

There are three main types of NAT configurations, each with different levels of connectivity:

  • Open NAT – Your console has a public IP address directly on the internet. Allows free communication for gaming but less security.
  • Moderate NAT – Your console is behind a router doing basic NAT mapping. It should work for most games.
  • Strict NAT – Uses more restrictive port blocking. It will likely cause connection issues for gaming.

Ideally, you want an open or moderate NAT. A strict NAT blocks too many ports, making it hard to connect consistently to game servers and other players.

How to Change Your NAT Type through Your Router

The most common way to change your NAT type is by adjusting the settings on your router:

Port Forwarding

  • Log into your router dashboard and find the port forwarding or virtual server settings.
  • Forward the specific ports your console needs for gaming to its local network IP address. For example, forwarding ports 80, 443 and 1935 to IP for a PS4.
  • This opens those ports only for your console rather than the whole network.

Change Router NAT Mode

  • If your router has a NAT mode setting, change this to “Open” mode. This completely removes NAT at the router level.
  • Be aware this disables NAT security and exposes your whole network.

Assign Static Local IP Address

  • Give your console a permanent local IP address in your router, like
  • This ensures port forwards always apply to your console if its IP changes.

Place Console in DMZ

  • As a last resort, place your console’s IP in the router’s DMZ or demilitarized zone.
  • This essentially puts it outside the firewall, which opens all its ports but reduces security.

Refresh Changes

  • Save your router changes and restart your console, or do a full reboot of the router for settings to take effect.

Check NAT Status

  • Go to your console network settings to check if your new NAT type is open.
  • If still moderate/strict, double-check router settings and reboot.

How to Change Your NAT Type without a Router

If you connect your console directly to your modem, you can try these NAT change options:

Enable UPnP on the Console

  • UPnP (Universal Plug and Play) auto-configures port forwarding on supporting devices.
  • Enable UPnP under your console’s network settings to let it manage NAT with your modem.

Set Up Port Forwarding

  • Some consoles allow manual port forwarding under network settings if not using a router.
  • Forward the usual gaming ports to your console’s IP for open NAT capabilities.

Use Ethernet Over WiFi

  • Connect via ethernet cable to your modem to reduce NAT restrictions from wireless connections.

Change DNS Server

  • Try manually assigning the DNS server on your console to an alternative like Google DNS or Cloudflare.

Connect through Mobile Hotspot

  • Tether your console to your smartphone mobile hotspot, which typically uses more open carrier-grade NAT.

Request Public IP from ISP

  • As a last resort, contact your ISP and request a public static IP address, which gives you an open NAT.
  • This will likely incur an extra monthly cost.

NAT Type Change Troubleshooting

If you still have a strict or moderate NAT after making changes, here are some troubleshooting tips:

  • Reset router to defaults – Start from scratch and reconfigure port forwarding.
  • Check firewall settings – Ensure the firewall isn’t blocking required gaming ports.
  • Confirm local IP address – Make sure port forwards are assigned to your console’s current local IP.
  • Test with direct modem connection – Plug your console directly into the modem to isolate router issues.
  • Check for IP and port conflicts – Use network tools to ensure no conflicts exist.
  • Power cycle devices – Fully power down, then restart your console and router.
  • Contact ISP support – Explain the issue and ask if there are any ISP-level restrictions.

Frequently Asked Questions

Here are answers to some common questions when changing NAT type for gaming:

Having a completely open NAT removes firewall protections, so take care of enabling it on all network devices. Limit it to just your gaming console. Make sure other devices have strong antivirus and firewalls.

An open NAT ensures minimal connectivity issues that could cause lag due to blocked ports. But many other factors also affect latency, like distance to game servers. Don’t expect miracles.

In most cases, yes, a public IP puts your console directly on the open internet. But in some rare instances, ISPs can still implement NAT on public IPs, too.

Yes, through proper router configuration, you can forward specific port ranges and IP addresses for each console on your network to have different NAT types.

While this is an easy way to open all ports, it does carry security risks. Your console’s firewall becomes your only protection against attacks. Use DMZ as a temporary troubleshooting test, not a permanent fix.


Adjusting your NAT type to be more open can significantly improve online gaming connectivity and performance. The most reliable way is configuring advanced port forwarding rules on your router specific to your console’s needs. If no router is present, tweaking console network settings provides alternative options. While an open NAT improves the gaming experience, it comes with reduced security – to find the right balance for your setup.
