Google Wifi Pro. IPv6 not working with All-Fi hub ATT router even when in passthrough mode.

[Apsilon778]

Hello,

I want to know how I can be able to natively access IPV6 because when I run an online test on the google Wi-Fi pro behind the gateway this fails and says it doesn't support it, however when I plug in directly it passes. 

Mainly I'm looking to see if this is actually possible given the gateway's functionality or if passthrough restricts ipv6 support entirely.

Do you run double NAT, as in your gateway/modem is not in bridge mode?

That might affect IPv6. About Nest Wifi and IPv6:

I checked into this, and the setup right now passes a public IPv4 address to the router. This would not create a double NAT scenario; however, it makes me wonder if this is just a limitation of the All-Fi gateway's passthrough function.

I use the passthrough mode offered by the gateway, there is no bridge mode for the gateway they provide. This assigns the public IP of the gateway to the router behind it. Configuring IP Passthrough and DMZplus - AT&T Business AT&T Internet Customer Support (att.com)

There is a default server option...this option forwards all traffic to a specified IP on the network.
