To ensure better monitoring of my home network (parental control) I tried and set up a Raspberry Pi with dnsmasq and added in some rules to the dnsmasq.conf, that basically come down to the following:
I set this up, and as long as I use IP addresses that are outside the range of 192.168.178.###, everything works fine. I now planned on wirining these websites with a local warning message so that not only the browser shows an error, but the user gets a warning.
To process all DNS queries though the Pi, I used the Fritz!Box settings and set both primary and secondary DNS server to the Pi's address. Everything resolves as wanted, except for domains that thus resolve into my local network. Is my router just trying to 'protect me' from websites redirecting to my local network or what's up?
Thank you for your time and help!
