3 XboxOne Consoles with a strict NAT on same network

I have 3 XboxOne consoles on the same network. All NAT types are strict. I forwarded ports for one console and it went open. I then realized I can not apply the port forwarding rules for all 3. Any feedback would be great. I am using the Xfinity router
provided by Comcast. Would there be a better router option for me to purchase to get these all working properly, or is there a better way of managing the settings?

Correct, with 3 Xbox 360 consoles on the same connection, you will likely need to adjust network settings for optimal results. Could you review our Strict or Moderate NAT guide? That should help you set up port forwarding to your consoles for the best possible
connection.

Port forwarding question

I have discovered why my X1 reports a Strict or Moderate NAT sometimes and it's after one of the 360s uses one of the ports the X1 needs. As soon as a Live port is used for a 360 via UPnP, 3074 for example, the X1 drops to Strict.

This is exactly the reason why I use UPnP, because if 360 1 is using 3074, UPnP will map 360 2 to a different port number that grants the same access as 3074 allowing both to communicate with the Live service at the same time, thus granting an Open NAT to all connected 360s. The X1 is not triggering port forwarding via UPnP to utilise this feature, so is the device that suffers when a 360 is in use.

The PS3 used to have a UPnP enable/disable option on the console itself, which I thought was odd, but perhaps if the 360 had this, enabling it would tell the console to use UPnP, which once it uses UPnP to trigger the ports I'm sure it will resolve the multiple device issue.

For reference:

• When I have an Open NAT, the X1's Detailed NAT Information says: Your network is behind a cone NAT
• When I have a Moderate NAT, the X1's Detailed NAT Information says: Your network is behind a port-restricted NAT
• When I have a Strict NAT, the X1's Detailed NAT Information says: Your network is behind a port-preserving port-symmetric NAT

 

You would need a router with confirmed multi-console support to allow more than one xbox to get open NATs at the same time.

You should look for the network hardware information forums as that has information on different routers and whether they have confirmed multi-console support. It appears though that the vast majority of routers don't
