Hello,

I am using an Orbi RBR850 with the AT&T Fiber BGW320-500 Gateway and followed to the letter AT&T instructions as well as some found in this forum to configure the RBR850 in IP Pathrough mode. While everything appears to work fine, I frequently get the following message when I try to reach various websites: "DNS_PROBE_FINISHED_NXDOMAIN." I also had instances where devices connected to the Orbi via wireless tell me that they can't find the internet.

 

Just FYI, below is what I did to configure my RBR850:

1. Ensured Orbi was in DHCP mode: my Orbi RBR850 is set as " Use Router as DHCP Server"

2. Disconnected everything from the BGW320.

3. Connected the Orbi and my laptop directly to the BGW320. 

4. Logged into the BGW320 via browser.

5. Under the Device List Tab "cleared" and "rescanned" for devices. 

6. Under the Firewall Tab enabled IP Passthrough.

7. Selected Allocation Mode: Passthrough.

8. Selected Passthrough Mode: DHCPS-fixed.

9. In the drop-down menu Passthrough Fixed MAC Address the BGW320-500 listed a MAC address which differed by its last digit from the one on the Orbi device, hence I entered the Orbi MAC Address manually.

10. Clicked on "Save".

11. I finally completed the configuration by restarting the BGW320-500. Device>Restart Device>Restart
