    Check out this tutorial for google wifi https://help.firewalla.com/hc/en-us/articles/360048869274-Firewalla-Gold-Tutorial-Google-Wifi-Mesh-network-with-Gold-Beta-

    There is a little trick that will allow your google wifi to act like an access point or bridge...   Google as you said, doesn't want ever run in bridge / AP mode ...  (unlike other major router manufactures)

    I have the same question/issue. Hopefully you will post an update if you figure it out. Likewise I will myself.

    I believe I have figured out a workable solution.

    -On your AT&T Arris box make sure DHCP is still enabled (I had mine disabled and it was causing configuration options not to be available, casuing more headaches)

    -You will have to figure out a way to get the MAC address for the WAN port on the firewalla. Unsure of a good way to do this, but the way I did this was to setup Firewalla as a regular network device instead of a router at first, then using ARP to grab the MAC address. You can also get it from the Firewalla mobile app once the firewalla is connected to your phone under settings > about. Then after saving that off somewhere, I factory reset the Firewalla back.

    -On your AT&T Arris box go to Firewall > IP Passthrough. Set the passthrough mode as DHCPS-fixed. Here you will input the Firewalla MAC address. Make sure to save the changes and possibly reboot if necessary.

    -You can now setup the Firewalla from scratch again and use DHCP mode.

    Here is basically the same procedure (uses a netgear device, but essentially the same process)

    You actually don't even need to remember the MAC address with the BGW210. Under DHCPS-Fixed, the available clients will show up in a drop-down, one of which will be the Firewalla. Choose it and save, then reboot the Firewalla (or realistically just unplug/replug the cable) so it gets the new passthrough IP.
