Double NAT configuration
I'm having trouble configuring my RBE971 as a router behind my modem/router, which is itself configured as a router. I want to retain some of the router functions of my modem/router, but also benefi...

I thought I had replied, but I realize my message didn't go through. So, I'll start again...
Thank you very much for your analysis.
The 10G hub is a Zyxel XS1930-10.
I just tried again by connecting the RBR's WAN port directly to the router. The result is the same.
I also tried changing the RBR from 192.168.16.1/20 to 192.168.0.1/24. Same result.
I also tried solution #2, without success. I finally gave up :(
Ultimately, since I wanted to be able to take advantage of certain RBR features not available in AP mode, I implemented the following solution:
- the box in router mode at 192.168.1.0/24, to benefit from certain features and manage my wired PCs over 10G,
- the RBR in router mode at 192.168.16.0/20 to manage my numerous Wi-Fi devices, but without using the router function,
- a PC on both networks with dnsmasq to serve everyone via DHCP and DNS, and configured as a gateway to the box.
I'm not marking the thread as resolved because I haven't achieved exactly what I wanted...

Since there is no way to turn off NAT filtering on the Orbi, you have to "use the router function".
It would be nice if there was a way to turn that off (as there is on some other Netgear routers).
