Question about Asus Merlin Router behind a firewalla?

[AsusRouterUser]

I had a friend of one of my family members contact me because he was moving into my area and wanted my help getting his network setup, he needed a router so I recommend a Asus that we could put the Asus Merlin firmware on, he picked the RT-AX68U. However when he got here and I went to set it up I found out he had a firewalla, I had never even heard of this thing so I had to look it up and see what it was to even know how it was suppose to hook into the network. That was not a problem the firewalla connects directly to the modem and it has a firewall built into it, and then the asus router connects to it. But here is where my question comes in, he got some guy on the phone who had set this up for him where he lived before and he said that behind the firewalla should be only an access point and not a full router and that having a full router was LESS secure then having just an access point? I don't claim to be a networking guru or anything but I can't follow why this would be the case or that it is true in anyway. If I am wrong I would really like to know, this just makes no sense to me at all.

I too have never heard of a firewalla; I wondered if it was anything like a punka-walla, but for firewall duties.

behind the firewalla should be only an access point

In order to use all Firewalla features as described - yes, it needs AP only.

I was expecting some sort of snake oil device, but a cursory search indicates otherwise.

A bit pricey?

having a full router was LESS secure

This statement is incorrect about security, but unnecessary complication with double NAT configuration and Firewalla won't see the actual clients on the LAN side and won't be able to monitor and filter anything separately. The cascaded router WAN IP will be the only client visible for Firewalla. Asus RT-AX68U is End-of-Life model now and perhaps used as AP is the better option long term. Unfortunately, Firewalla is VLAN capable appliance, but RT-AX68U is not. Most home routers don't have user configurable VLANs on the LAN side. This limits some of Firewalla capabilities. A business class AP with VLAN support is the better fit for Firewalla and similar firewall appliances.

A bit pricey?

Some models are much faster than any home router x86 hardware. The higher specs appliances they use are similar to Protectli Vault, the UI is built on top of Ubuntu Linux, it comes in user-friendly form pre-installed and ready to go. It's a nice project and getting somewhat popular. The same functionality can be achieved on OPNsense/pfSense appliance of course, but requires much more networking knowledge. Firewalla offers professional features and covers higher demands market as well. It also has nice modern UI UniFi/Omada style with both App and Web available. Asuswrt is like blast from the past 2010 UI. Some folks like to play with the UI and like "fresher" design.

I thought the same thing when I first saw it.

Thank you for confirming it is not LESS secure, that is the part I was really not understanding, because I could not wrap my brain around anyway it could be less secure.

Not less secure, but doesn't make sense to run it as a router when Firewalla is the actual Internet facing device.

Pricey is subjective. RT-AX68U is quite pricey as well. It arrived in mid-2020 at around $200 price tag and got discontinued in the beginning of 2024.

Firewalla I would think would fit with consumer gear and may be easy to use. Firewalla seems to be a layer 2 device but it does not do real networking with a layer 3 switch which I would want.

Firewalla seems like an easy to maintain firewall for non-networkers. I have not seen anything on hacking it yet. It is set up like a small business network.
