I have an unbound instance running in my local network. This is configured to resolve my.hostname to the local IP of my home server. This works fine on all devices except for the two GOS devices I have. I suspected that the DHCP config is at fault and somehow not providing the correct DNS resolver address but dnsleaktest claims otherwise.
After some testing I found that the query will fail when the found IP is within a range reserved for local networks but it will work for public IPs and even something like 192.18.0.0/24. This leads me to believe that there is some kind of DNS rebind protection happening in GOS. Is this the case and If so can it be disabled?
