Unable to login to Corporate Office 365 portal
Hello Everyone,
I've been using RBK53 at home since nearly 2 years. It is currently on firmware 2.3.5.30
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!

Hi,
There could be lots of issues here that need to be investigated:
1) Firstly is your Orbi in Router or AP mode?
2) Can you confirm that the web service redirect is getting resolved by DNS; what is the URL and service port you are trying to connect on and can you ping it?
3) Is there a firewall/filter rule blocking access somewhere?

Hello,
sorry for the delayed response
1) The ORBI is in Router mode. 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.
2) Yes, the destination host is correctly resolved but it is not pingable or telnet-able. I believe that is by design for the security of the destination host that processes OAUTH requests
3) No, there is not. In fact, i have tried to explictily add port 80, 443 and HTTPS sites as NOT blocked in the Orbi setting's for "Block sites" and "Block services". Did not make any difference.
Thanks!
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
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. 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

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

I have the same scenario and it works without issue. I have the Orbi in AP mode, I bet you don't. I'd try two things, connect directly to your ISP's modem via ethernet and see if the issue persists. If it does, talk to your ISP. I'd also try a different browser/clear cache.

You're right, The ORBI is in Router mode - but it has to be like that. 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. There is no double-NAT condition.
No, the problem does not happen if I take the Orbi out of the equation completely and connect directly to the ISP's modem and then to the internet.
Regards,
Any progress on this?

I had the same issue. Solution - Login to the router > Advanced > WAN Setup > NAT Filtering changed to "Open"
Office 365 now works perfectly - no other issues...yet ;) I'll update if something changes.
