I was hoping for some more ideas on why DNS won't respond to UDP requests but responds just fine to TCP requests. I've trimmed down the dnsmasq.conf file to the minimum for what I need. The conf is in my last message. I've commented out all unnecessary enties in the host file. I've disabled access to the resolv.conf file. I am explicitly referencing one and only one DNS server for forwarding. The referenced DNS server responds to UDP requests just fine. I've disabled and removed the firewall on the dnsmasq machine. What are the other possible causes of not receiving responses from UDP requests? <br>
