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:

Which in turn points to this:

Linksys | Networking & WiFi Technology

Experience fast, reliable, secure and easy to use WiFi when you level up with connectivity solutions made for home, business, and enterprise from Linksys.

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