What is the Mfr and model# of the ISP modem the NG router is connected too? Built in router here by chance? If so, This would be a double NAT 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=desktop

I have an issue which i have been simply "living with" since the day I got this router which is that I am unable to login to my work account on Office 365. I work in IT so i am pretty tech-savvy in these matters but as far as controlling or influencing the technical setup of Office 365 in my organization is concerned, I have no power there.
Basically the issue is that if I want to access my Office 365 portal, i need to login to my corporate microsoft account on portal.office.com
Since my organization is using a Hybrid setup, the AD authentication of my account is done internally using an on-premise AD and then transfers to the Office 365 host.
I am able to see the credential prompt on portal.office.com - however, as soon as it re-directs to the web-service for authentication, it times out and then I see the "Page cannot be loaded" .
What is important to note is that this only happens at home when I am on the Orbi network. If I connect from anywhere else, be it a Coffee Shop, my mobile hotspot or at a friend's place that uses alternative router brands, I do not encounter this issue.
I checked internally and i got a tip from my organization that I should have IPv6 enabled (no clue how on earth that helps). It is set in Auto-detect on my Orbi but I know for a fact my service provider in Dubai does not use IPv6 on the WAN side.
I also adjusted the MTU size to 1488 after doing some ping tests but this did not help either.
Is there anyone else who has a similar setup with their work-account and encountering the same issue?
Thanks very much!
Hello,
here's my feedback/answers
It's a Huawei all-in-one fibre optic gateway router the ISP provides in all homes to deliver all services in one appliance (traditional approach by most ISPs that have fibre-optic infrastructure). I can't check the exact model number at the moment - it's buried in the ceiling and i need a ladder to get to it.
1) and 2) --> The service provider's fibre-optic modem only provides a bridged link. They provide you with a set of credentials for PPPoE which need to be configured on the user's home router, i.e. in this case for Orbi it's the internet link properties. It's definately not a double-NAT condition.
Thanks!
Hi,
I believe Office 365 uses other TCP ports and that is what could be blocked by your Orbi. I would speak with your IT asking which ports need to be allowed?
I know some of the following TCP ports need to be allowed:
443
25
465
587
CheerZ
What happens if you configure the gateway modem for router mode and then configure the Orbi RBR for router mode, removing the PPPoE connection configuration. Input the IP address the RBR gets from the ISP modem in to the modems DMZ/IP Pass-thru feature?
Or configure the ISP modem for router mode then configure the Orbi RBR for AP mode?
Couple of options to help you narrow down where the problem may be.

We just ran into the same thing. if you try accessing http://portal.office.com and you are presented with a netgear page, that is the cause of your issues. We were unable to install Office 365 while behind a Netgear router because of this issue. Swapped out to a different router and were able to install without any other changes to the PC or network. Wasted 2 days on this issue to find out it's an issue with the Netgear router intercepting the traffic for this address http://portal.office.com (try it without https).

What model NG router are you referring too?
