Because any unsolicited inbound packets get dropped at the router (since decades ago!) then I can't guess why all this is required.
DD-WRT and Open-WRT have hardware lists so a nod to those lists. But I'm not paying for something I don't agree with.
I now have 6 IoT devices on my home network. This network is fed from the FIOS ISP router which probably has not in years. So I am looking into purchasing a new router. I want some level of protection for the IoT devices, most of which will not get updated. In doing some research there are three categories:
1. Routers with anti-malware built-in. Examples are Bitdefender BOX 2, Norton Core Secure and ASUS AirProtection.
2. Routers with advanced packet sniffing. Examples Cujo AI, Dojo and RATtrap.
3. Open source routers. Various types of hardware and third party software such as DD-WRT and Open-WRT.
Cost goes down as you go down the list but maintenance goes up as you go down the list. I would like to hear your opinions on this.
