Xbox one behind Meraki MX64 security Appliance STRICT NAT

cwtoz · Mar 16, 2016

I am having trouble getting NAT set to anything other than STRICT for XBOX ones behind a Meraki MX64 security appliance. All ports are already forwarded. I get "Your network is behind a port-symetric NAT. Has anyone been able to get this working with
a Meraki MX yet?

:)

Need help with my NAT type

I have been trying everything to get my NAT type open but nothing works because no one has the same NAT type as mine:

NAT type: Strict

Your network is behind a port-symmetric NAT

its very frustrating having a strict NAT type so please help

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

Heya cwtoz.

Security appliances aren't supported for network connections on the Xbox One unfortunately. Have you tried bypassing the MX64 and plugging directly into your modem to see if there's a change in your NAT type?

Strict - Your network is behind a port-preserving port-symmetric NAT.

Update, no settings have changed.

Have strict nat again, detailed nat is "your network is behind a port preserving port symmetric nat.

I switched it to Energy Saver mode and I am still getting a Strict NAT. I've turned off UPnP and my Firewall as well now. For about 5 minutes earlier with this exact set up I showed an open NAT with a Cone NAT but now it's back to Strict NAT with it being
behind a Port-Preserving port-symmetric NAT

Taidara. There is no bridge mode on that router, but I did change the IP address from private to public, and that changed my NAT from strict to moderate, and now it says "your network is behind a cone NAT" Moderate is better than strict, but the battle continues!!!!!
