Connecting LAX20 & RAX75 together

Question

I'm wondering if this is possible...&nbsp;Cable Modem -&gt; LAX20 (Since it can do both Cable Modem Connection &amp; Cell) -&gt; RAX75 -&gt; Rest of network.&nbsp;Now, I plan on shutting off the WiFi on the LAX20, so I can use it similar to a cradlepoint.&nbsp; I also plan on having this on the 192.168.1.x/24 network.&nbsp; I plan on moving my RAX75 to a 10.2.1.x/24 Network configuration.&nbsp;My Goal is to be able to have my Cable Internet as a Primary Connection and the Cellular internet as a backup connection, as I have a need to have a constant network connection for work.&nbsp;&nbsp;&nbsp;In theory, this should work, as I'm creating 1 segment that has extra security (2 Firewalls), and another DMZ-esce higher segment.&nbsp;&nbsp;&nbsp;Is my thought process correct?&nbsp; If necessary, I can create a Network diagram.

I would prefer NOT to do that, as I want all the WiFi to go through the RAX75 (More Channels). I have a huge network (over 64 devices) and want all communications between the 2 routers to be hardline, not WiFi. I also want to segment off the Core Network (which would be off the RAX75) from the DMZ Network (LAX20).&nbsp; The attached diagram may help to explain.

I think you may be missing a big part of this. I don't want a Flat Network; I want a tiered network with 2 DHCP Sources. One will be confined to a /28 (the 192.168.1.x Tier {DMZ} the LAX20), and the other will be shrunk to a /25 (The 10.2.1.x Tier {Secure} the RAX75).&nbsp; &nbsp;&nbsp;Because I'll need 2 DHCP Servers (1 on each segment), I don't think Access Point (AP) mode will work. My understanding of how AP mode works in Netgear is that it turns off the AP Device's ability to issue DHCP. (I'd like it if the LAX20 supported LACP Aggregation on its ethernet ports so that I can utilize the LACP Uplink on the RAX75)&nbsp;Now, Based on the drawing and what I asked for at the beginning, Will what I want to do work?

Wow... I never knew this would start a flamewar...&nbsp;Let me explain a few things...&nbsp;1) I never said I was planning on using Netgear's Single IP version of a DMZ. There are other ways to create a zone with fewer restrictions.&nbsp;2) As to the Concurrency Between Cable &amp; Cellular, I'm not sure that is what I'm asking... More of if the LAX20 would use HSRP, OSPF, or another router protocol to route traffic.&nbsp; The preference is that when Cable drops, Cellular takes over. Yes, I'm aware that HSRP is a Cisco Protocol.&nbsp; There are Open Protocol standards that do similar functions.&nbsp; I don't want both paths open simultaneously.&nbsp; If Cellular has nothing to do, it can stay in the state of "I'm connected to a tower, but I'm not handling traffic."&nbsp;3) I was honestly looking for a second opinion on if what I wanted to do would work.&nbsp; My expertise is not in Network design. (I do have some experience in doing it, but I also have Cisco Folks at my disposal when I do that for non-consumer customers.) My knowledge is mostly in Data Center Design.&nbsp;Thank you all for your time, and keep it Civil.&nbsp; 😃

I'd set the RAX75 for AP mode while leaving the LAX20 has you main host router:

AP mode would be a hard line between the RAX and LAX router.&nbsp;
