RBR850+Nighthawk MR5100 issues
I have an ATT cellular modem (Netgear's MR5100) connected to the Orbi 850 router with two satellites. I am having NAT 3 issues with my PS5. I have tried putting the PS5 in a DMZ, port forwarding, etc. I switched from secure to open NAT in the orbi admin MR5100 and not something I can change. Does anyone else have this setup, and if so have you dealt with this problem? When I set up my home system, in the MR5100 settings, I turned on IP passthrough, turned off DHCP, disabled ethernet standby, and switched the usb-c to charge only. Then I connected it to my Orbi. Any help would be appreciated!

Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktopTry option #2...
