Description

When you don't specify any DNS servers, you can still tick the "DNS Query Forwarding" and save the configuration, resulting in broken DNS not resolving anything at all.

$ grep forward /var/unbound/unbound.conf
forward-zone:
        forward-addr: 127.0.0.1

same is true of dnsmasq. It's not as simple as just checking for user-defined DNS servers, as those with dynamic WANs often don't specify any.
