Nat Type Open Call Of Duty MW3/Warzone

[Caaq]

Hey,
Just recently switched internet providers and to a fiber connection. Picked up the xr1000 with that.
Prior to this, I would always have an open nat type in game, however since the upgrades I haven't been able to get it back. The methods/troubleshooting (not in order) I have tried are;

* uPnP on, aswell as off
* Port forwarding ( + static ip )
* Allowing through the firewall
* Inbound and Outbound rules in firewall
* Windows Powershell
* Reserving IP address for my PC through DumaOS

It was usually an otherwise simple easy fix when COD games would be on moderate for me in the past. However, right now I'm quite stumped as for what to do.

Any help is greatly appreciated !

What is the model of the modem/router the XR is connected to and how have you set that to ensure all traffic flows to the XR? E.g. XR in its DMZ, modem/bridge mode

Set NAT to Open in WAN settings and then check again to see if it helps

XR1000 is connected straight to the fiber connection box.  

Tried setting NAT to open in WAN settings also and that didn’t help change it.

Disable the Geo-Filter, reboot the game and check again please

Tried that again just now, (unless i disabled it incorrectly) still no luck sadly.

To disable either toggle filtering mode or delete the device. If you follow the CG-NAT section at the bottom of this guide: https://support.netduma.com/en/support/solutions/articles/16000076587-dumaos-optimal-settings-guide-open-nat what results do you get?

I'm pretty certain that my ISP uses CGNAT as a default. What should I do? Getting frustrated at how much troubleshooting needs to be done. I don't get why it was so simple with my old ISP to get open NAT Type but with the new ISP it's a mission.

That explains it then, there are only a few options to get an Open NAT in your situation:

1. Ask your ISP for a static public IP - they may charge for this
2. Change to an ISP that doesn't use it
3. In some cases using a VPN help get you an open NAT while connected to it.
