So, how does DNS on my network work then? All of the machines on my network are configured via DHCP to go to the router at 192.168.2.1:53 for DNS requests. Doesn't dnsmasq see those requests, and forward on the ones it cannot answer locally to the configured servers?

I'm not using AdBlock. Instead, I have specified the addn-hosts option in dnsmasq and those files contain blocked servers with an IP address of 0.0.0.0.

There should be no AdBlock related rules in my firewall as I'm not using it, but I'll be looking at what is there.
