Seeing a “Double NAT” error on your Xbox or PlayStation means your console’s network traffic is being translated twice, which completely ruins peer-to-peer matchmaking, blocks voice chat, and causes random disconnects in multiplayer games. In my decade of setting up home gaming networks, this almost always happens when you have two routers fighting for control over your connection. Follow the steps below, and we will bypass the hardware conflict to get you an Open NAT type today.

Why Are You Seeing This Error?
Understanding the technical routing mechanism helps you figure out exactly which piece of hardware you need to adjust in your specific house.
-
Two Routers Chaining (Router Behind a Router): You plugged a personal gaming router or a mesh Wi-Fi system directly into the gateway provided by your Internet Service Provider (ISP). Because both devices have active firewalls, your data gets trapped in two separate private networks.
-
Overlapping DHCP Servers: Both the ISP gateway and your personal router are actively trying to assign internal IP addresses. When a game server sends a data packet back to your console, the first router translates it, but the second router drops the packet entirely because it does not recognize the original translation protocol.
-
Carrier-Grade NAT (CGNAT): Sometimes, your internet provider is completely out of standard IPv4 addresses and pools your connection with hundreds of other customers before the signal even reaches your house. I see this constantly with cellular internet (5G home internet) and smaller regional fiber providers.

What You Need Before Starting
-
A computer or smartphone connected to your home Wi-Fi network.
-
The admin login IP address (usually 192.168.1.1 or 10.0.0.1) and the administrator password for your ISP-provided modem/router combo. These are printed on a physical sticker on the back of the hardware.
-
Your Xbox or PlayStation powered on and connected to the network so we can pull its exact internal IP address.
-
An Ethernet cable, in case a wireless setting change kicks your computer off the network and you need a hardwired backdoor back into the router settings.

Step-by-Step Solutions (Ranked Easiest to Hardest)
Method 1: Put Your Personal Router into Access Point (AP) Mode
If you want to keep using your personal high-end router for Wi-Fi coverage but let your ISP gateway handle the heavy networking math, this is the fastest, cleanest fix.
-
Open your personal router’s mobile app or log into its web interface from your computer browser.
-
Go to the Advanced Settings, System, or Administration tab.
-
Select Operation Mode or Router Mode.
-
Change the setting from Wireless Router to Access Point (AP) Mode.
-
Click Apply or Save. Your router will reboot.
-
Once the reboot is finished, your personal router will stop trying to assign IP addresses, turning off its internal firewall and letting the ISP gateway pass traffic directly to your console.

Method 2: Enable Bridge Mode on Your ISP Gateway
This is the most effective fix if you bought an expensive gaming router (like an Asus ROG or Netgear Nighthawk) and want it to handle all the processing. This turns your ISP gateway into a “dumb” modem.
-
Open a web browser on your computer, type your ISP router’s IP address (like 10.0.0.1 for Xfinity or 192.168.1.254 for AT&T) into the address bar, and press Enter.
-
Type in the Admin Username and Password found on the physical sticker on your ISP hardware.
-
Look for a menu section named Advanced Routing, WAN Setup, or Network Settings.
-
Find the Bridge Mode or IP Passthrough option and toggle it to Enable.
-
Click Save or Apply.
-
Unplug the power cable from both your ISP gateway and your personal router.
-
Plug the ISP gateway in first and wait exactly two minutes for it to grab the public IP from the street.
-
Plug in your personal router. It will now pull a clean, single NAT IP.

Method 3: Put Your Console in the DMZ (Demilitarized Zone)
If your ISP locks you out of Bridge Mode (which I see often with strict fiber providers), you can force your router to completely expose your console to the internet. This bypasses the local firewall entirely, eliminating the double NAT strictly for your gaming device.
-
Turn on your console, go to Settings, select Network Settings, and write down its specific IPv4 Address (e.g., 192.168.1.15).
-
Log into the web interface of the router that your console is directly connected to.
-
Locate the Security, Firewall, or Advanced Setup menu.
-
Click on DMZ or Exposed Host.
-
Check the box to Enable DMZ and type the IP address you wrote down into the DMZ Host IP Address field.
-
Click Save and restart your console.

Method 4: Call Your ISP to Remove Carrier-Grade NAT (CGNAT)
If you only have one router in your entire house and still get a Double NAT error, your internet provider is sharing your IP address at the street level. No setting on your router will fix this.
-
Call your ISP’s technical support line.
-
Tell the agent: “I am trying to play multiplayer games on a console, but I am trapped behind a Carrier-Grade NAT. I need a static IP address or a public, dynamically routed IP.”
-
Many providers will instantly opt you out of the CGNAT pool for free when asked, while others might charge a small monthly fee (usually $5) for a dedicated static IP.
-
Once they provision the new IP on their end, restart your modem to apply the change.

Frequently Asked Questions (FAQ)
Why does Double NAT affect party chat but not Netflix or YouTube? Video streaming relies on client-server connections. Your console sends a single request to the Netflix server, and Netflix blasts the video data straight back down the open pipe. Multiplayer gaming and party chat rely on peer-to-peer (P2P) connections. Your console has to actively listen for unpredictable inbound connections from other players’ consoles. A double NAT acts like two locked doors; the inbound connection hits the first door, cannot find the specific map to your console, and drops the connection entirely.

Should I use UPnP instead of Bridge Mode? Universal Plug and Play (UPnP) allows your console to automatically open specific router ports on the fly. However, UPnP cannot jump across two separate routers. If you have a chained setup, UPnP will only open the ports on your personal router, while the ISP gateway blocking the street connection remains completely closed. You must fix the double NAT layout first before UPnP will work properly.

Does using a wired Ethernet connection fix Double NAT? No. Connecting an Ethernet cable improves your latency (ping) and prevents wireless packet loss, but it does not change how your router translates IP addresses. If your network topology is chaining two routers together, you will experience a double NAT regardless of whether your console is hardwired or wireless.

Is putting my console in the DMZ a security risk? Putting a Windows PC in the DMZ is highly dangerous because it exposes the operating system directly to internet traffic and malicious port scans. However, gaming consoles are heavily locked down, proprietary closed-box systems. They do not run standard executable files or open background services. Placing an Xbox or PlayStation in the DMZ is widely considered safe practice to resolve strict NAT issues.

How to Verify the Fix
On your Xbox, press the Xbox button, go to Profile & system, select Settings, go to General, click Network settings, and click Test NAT type.
On your PlayStation, go to Settings, select Network, select Connection Status, and click Test Internet Connection.
Confirm your NAT Type now explicitly reads as Open (or Type 1/Type 2 on PlayStation) without any double NAT warnings appearing on the screen.
