I debated deploying Firewalla (Gold or Purple) model ~ 3 months ago as the front facing internet door - right when the "TechCrunch" article was published. I also dove into many earlier reviews and liked what I read. I also looked into the support forums - great place to find about customer service.
One of the sticking points I saw was their current implementations there is a limit on the # of banned country codes it would accept. I think the "Purple" was 10 and I have at least 15+ in skynet today. I understand their design goal to KIS but that hit pause button for me. Note: The Gold model has an unlimited # of banned countries.
IMHO, the "Purple Firewalla" is a near-perfect companion for traveling whether it be hotels or home-away/air-b-n-b rentals. I
never trust those things natively. With it's very
limited wifi, it's perfect for same-room deployment as it was never intended to cover a whole house (wirelessly) and they make that very clear.
So using Firewalla as the main front doors with the most excellent ASUS routers as WAPs is attractive for a KIS(er) but more generally hardened approach - aka thinking in-laws and less tech savvy family members we all tend to support in these parts!
My network is already subnet for prod/work and IOT+other traffic (kid's machines) which I do not trust quite as much. I also use 2 older RT-AC68U as WAPs and RT-AX86U as the main front doors today.
Please update this thread on what you learn and determine with your experiments! Peace. Later.
