Setup cascade router

[PCE]

I need help with information on setting up cascade function on my bgw320-505 to ASUS GT-AX1100. Trying to eliminate the double Nat on Xbox’s and other devices.

A Google search points to this page:

Setting Up ATT Fiber (BGW320-505) With your Router (DD WRT) | Norman's Oven

ATT Fiber Setup with your own Router using DD-WRT

www.normansoven.com

Which in turn points to this:

IP Passthrough mode setup for AT&T U-verse®

IP Passthrough mode setup for AT&T U-verse®

So it looks like the answer is to configure IP Passthrough mode.
