What is NAT?
NAT (Network Address Translation) enables your devices to share the IP address that’s provided by your Internet Service Provider. NAT changes your public IP address to a private IP address. This entire process is beneficial for you as it secures your home network by blocking direct access to your local IP address.
What is Double NAT?
A Double NAT occurs when you connect your router behind another router. This ends up creating two different private networks. For example, connecting your Linksys router behind a modem/router that’s provided by your ISP will create a Double NAT.
Having a double NAT does not mean that your devices won’t have access to the internet, but you may face significant issues when playing online games, trying to open a specific service port, connecting to a VPN, or accessing a site with SSL certificate.
A Double NAT might also prevent the devices connected to the first private network to not communicate to the devices that are connected to the second private network. Fortunately, there’s a way to fix double NAT whether it’s on a gaming console or your network router.
Fix Double NAT on an Xbox
This process is recommended for most people as it doesn’t require you to rewire your entire network. The process disables NAT and any other routing functions. By doing so, your internet traffic passes through the modem provided by your ISP.
- Navigate to your router’s login page.
- Log in to your router.
- Head over to the wireless options on your router.
- Enable Bridge Mode.
- Save your changes.
Once you’ve made the changes, simply restart your Xbox and run network diagnostics again.
Fix Double NAT via Your Router
Fortunately, double NAT can be avoided by configuring it via your router. Here’s the process:
- Head over to your router’s login page.
- Log in to your router using the required credentials.
- Navigate to the wireless options on your router.
- Enable Access Point (AP) Mode.
- Save your changes.
Once you’ve made the changes, restart your router and devices connected to the router.
