Have xfinity router/modem as primary, RS300 router is plugged into xfinity router, R8000 router is plugged into RS300 router - the RS300 router has a ton of definitions in it, reserved addresses, port forwarding, VPN , etc so I hesitant to do a factory reset.
It replaced the R8000 which had all of these definitions and working DDNS too, As long as I keep the R8000 up it's ok, can just use the hostname for external connections

in IP address IP Range
xfinity modem/router Coax 10.0.0.1 ( 10.0.0.2 - 10.0.0.254)
RS300 router 10.0.0.155 192.168.0.1 (192.168.0.2 - 192.168.0.254)
R8000 router 192.168.0.200 192.168.25.1 (192.168.25.2 - 192.168.25.254)
Hope that helps
Question - does anyone have a RS300 with Dynamic DSN on with a hostname from NoIP.com where show status works?
Thanks

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
https://kb.netgear.com/30187/How-to-fix-issues-with-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.
