NAT Type failed to obtain, but I have open NAT?

what's your nat type? it's best to have a open nat type .

I just checked and yes my NAT is set to open.

Did you try changing your NAT type? The helpdoc says:

Open:

With an OPEN NAT type, you’re able to chat with other people, as well as

join and host multiplayer games with people who have any NAT type on

their network

Moderate:
With a MODERATE NAT type, you’re able to chat and play multiplayer games

with some people; however, you might not be able to hear or play with

others, and normally you won’t be chosen as the host of a match.

Strict:

With a STRICT NAT type, you’re only able to chat and play multiplayer

games with people who have an OPEN NAT type. You can’t be chosen as the

host of a match.

-- So I take that to mean if you have STRICT NAT, and if anyone in the group DOES NOT have an OPEN NAT type you are going to have problems.

Are you both running STRICT NAT type?

I have a NAT Setting on my router but it is set to on? When I have it on automatic my NAT type stays open. I don't know why DMZ won't keep my NAT type open.

Hi Jirpet! I hope you are well, delighted to be able to offer you my help!

From what I understand this is a problem with multiplayer games and NAT, so follow these steps to resolve this problem, but first we must check the type of NAT you currently have.

1. Press the Xbox button to open the guide.
2. Select Profile & system > Settings > General > Network settings.
3. Under Current Network Status, the NAT Type field shows your current NAT type.

To resolve this issue, you need your NAT type to be Open. You should also make sure there are no errors, such as when Incorrect Double NAT or UPnP Detected appears.

To start, check if you have any of the errors shown here:

- NAT Type: Not available (displayed in Current Network Status on the Network screen)
- Cannot obtain a Teredo IP address (appears after running Test Multiplayer Connection on the Network screen)
- Error code 0x89231906 (appears when you try to join a group chat session)
- Double NAT detected (displayed in Current Network Status on the Network screen)
