But the Internet of Things is becoming ubiquitous. In my case, I have a Tivo setup that has external connections to remote servers and a Fitbit scale that connects remotely via my Wifi. You might have a networked thermostat, a clothes washer, and even a refrigerator. Then, you might even have Smartphones that take advantage of your WiFi router. I configure a "guest" subnet on my router that hosts the Wifi router, and a separate DMZ subnet for the IOT devices. Then I also use the host-based firewall on my Leap systems, you can't be too careful these days, even your hardware router could get compromised. By the way, my SuSE desktop was once compromised around 1998 via the cable-modem. I had installed SuSE 5.2 which still had portions of the documentation in German. I didn't configure the host-based firewall because I couldn't figure out how to do it! Well, maybe I was a bit lazy too. At any rate, it was remote-root compromised via a mountd bug. I caught it right away, so there wasn't any damage, but the lesson was learned! Host-based firewalls are good things, even if you don't think you need it. Regards, Lew
