How do I get rid of double nat on a gateway network

Hello!

Hope you are well. I'll be glad to assist you.

To eliminate this problem it is necessary to make some adjustments in your router, here are the general instructions

It is best that this type of configuration is done by your internet provider.

Best regards!

Hi timtima1

If you're using both a router and a gateway, you'll need to remove one of them from the network. First, try putting your gateway into bridge mode. Each manufacturer handles bridge mode differently; so you'll need to check with your manufacturer or service provider to find out how to do this.

If you can't put your gateway into bridge mode, try changing your router to function only as an access point. This will remove it as a NAT on your network.

Once you've changed either your gateway or your router settings, restart your Xbox and your network devices, and then check your network settings again to make sure that the double NAT message is gone.

Initial diagnosis: double NAT, which prevents you from getting open NAT. Your "modem" appears to be a gateway (modem+router), which if so creates a problematic double NAT situation when combined with your router. To verify double NAT is the issue, please
log in to the web interface of your router and note the WAN/Internet IP it reports (WAN IP, not the LAN IP!). If that IP differs from the one reported by
http://www.tracemyip.org, then your Xbox is behind multiple layers of NAT (double NAT) and getting open NAT will require special steps.

Basically, you have 3 options. One, you can put the gateway in bridge mode. Google the model of your gateway plus the words "bridge mode" and you will probably find instructions--e.g.

forums.comcast.com/.../1707801 (seemingly bridge mode on this model can only be done by a Comcast
technician)

.Once routing has been disabled on the gateway, use your router to forward ports via UPnP, manually, etc.

Two, as an alternative to placing the gateway in bridge mode, which can be complex for the inexperienced, you can try putting the WAN IP of your router in the DMZ on the gateway then use your router to forward ports via UPnP, manually, etc.

Three, you can get rid of the gateway and replace it with a modem-only device instead. Or, connect the Xbox One directly to your gateway and do not use your Belkin router.

The Xbox support site actually has a decent guide for NAT problems:

Hey Jack.

When Tormaz says multiple devices, he is referring to multiple network devices like Routers/modems and gateways. For more information on how to resolve this issue, please visit this article :

Hope this helps!

Check the steps in this support page, Double NAT detected. It usually occurs if you have 2 or more network access devices attached and they are not configured correctly. eg a router and a gateway or modem.
