I just recently purchased a used but functional NETGEAR Nighthawk Pro Gaming WiFi 6 Router (XR1000) w/ duma OS. The firmware version is 1.1.0.16_2.1.25. It is unclear to me whether or not a firewall is included w/ this router. Ive had SPI FWs w/ Netgear routers before, and i would prefer to have one w/ this router too. Does anyone know if one exists w/ this router? If so where would i find it? Do i have to get netgear armor to enable it? What about the DPI function? Does that apply to a built in FW thats included w/ the package?
