Hi Michael,

Thanks. for your comments.

 

Kpn in in the Netherlands is the provider and all providers supply there own modem.

That is how it is arrange in The Netherlands no other option on that.

on this Draytek the have a special socket for glassfiber entery .

 

So in The Netherlands i can't use the Orbi as a modem / without the draytek.

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.
