If you play online on your Xbox Series S or X, you’ve probably seen the term “NAT Type” when testing your network connection. A Strict or Moderate NAT can block multiplayer matches, voice chat, and online parties. Fortunately, fixing NAT issues isn’t as complicated as it sounds — and most solutions take only a few minutes.
Let’s explore how NAT works, what causes the problem, and how to open your network for the best gaming experience.
This guide covers both quick fixes and advanced router settings for Xbox gamers.
Understanding NAT Types on Xbox
NAT, or Network Address Translation, determines how your console connects to other players on the internet. There are three main types: Open, Moderate, and Strict. An Open NAT allows free communication with all players, while Strict NAT often limits multiplayer access or matchmaking. Moderate NAT works, but it can still cause delays or voice chat issues.
Most NAT problems occur because routers block inbound connections by default. Knowing which type you have helps you decide which fix to apply — from simple UPnP activation to manual port forwarding. Understanding this foundation is the first step toward smoother gaming sessions.
Check Your NAT Type and Network Status
Before changing any settings, check your NAT type on your Xbox. Go to Settings → General → Network settings → Test NAT type. If it says “Strict” or “Moderate,” your console has limited connectivity. Sometimes, simply restarting your console or router can refresh the connection and fix temporary issues.
Testing your network also shows if you have a “Double NAT” problem — when both your modem and router perform NAT simultaneously. In that case, you’ll need to adjust your setup to avoid this double layer of translation.
Enable UPnP on Your Router
The easiest way to fix NAT issues is to enable UPnP (Universal Plug and Play) on your router. UPnP automatically opens the necessary ports for your Xbox to communicate freely with game servers. Log in to your router’s admin page, find the UPnP setting (usually under “Advanced” or “Network”), and make sure it’s turned on.
After enabling UPnP, restart your router and Xbox, then retest your NAT type. In most cases, this simple change switches your NAT from Strict to Open without any manual configuration.
Use Port Forwarding for a Permanent Fix
If UPnP doesn’t help, you can manually forward Xbox Live ports. The key ports are 88 (UDP), 3074 (UDP/TCP), 53 (UDP/TCP), 80 (TCP), 500 (UDP), 3544 (UDP), and 4500 (UDP). Assign a static IP address to your Xbox first, then log into your router and open these ports for that IP address. This process gives your console a direct path for online traffic.
Once done, reboot both the router and Xbox. Port forwarding is slightly more advanced, but it’s the most reliable way to achieve an Open NAT type permanently.
Resolve Double NAT and Bridge Mode Issues
Double NAT happens when both your modem and router manage network translation, which can block connections. To fix it, put one device into “Bridge Mode” — usually your modem. This lets your router handle all the NAT processes. You can find the bridge mode option in your modem’s settings or contact your ISP for help.
After enabling bridge mode, retest your NAT type. Most gamers report immediate improvement once the double NAT layer is removed, allowing for smoother matchmaking and party chat.
Use DMZ as a Last Resort
If all else fails, you can place your Xbox in a DMZ (Demilitarized Zone) on your router. This exposes it directly to the internet, bypassing NAT restrictions completely. Assign your console a static IP, then enter that IP into the DMZ field in your router’s settings. It’s safe for consoles but should not be used for PCs or other devices.
After applying DMZ settings, restart your router and console once more. You should now see an Open NAT type and enjoy full Xbox Live functionality — though remember, DMZ should be your final option after trying UPnP and port forwarding.
Contact Your ISP or Xbox Support
If you still can’t achieve an Open NAT, your ISP may be using Carrier-Grade NAT (CGNAT), which requires their intervention. Contact them and ask if they can assign a public IPv4 address or enable port forwarding on their end. Xbox Support can also provide detailed guidance for your specific router model.
Sometimes, NAT issues stem from ISP restrictions rather than your home setup, so professional help is the best next step when all self-fixes fail.
Fixing NAT problems on Xbox Series S/X greatly improves online performance, matchmaking speed, and voice chat reliability. Whether you enable UPnP, forward ports manually, or solve double NAT, the result is a smoother and more enjoyable multiplayer experience. With a few tweaks, you’ll unlock your console’s full online potential and say goodbye to connection errors.
