I have just setup our EdgeRouter Lite to use the DNS Content Filtering service from "DNSfilter.com". The service is working correctly. After just one day of using the service, I checked the DNSfilter Dashboard only to find about 500 requests hitting their server for "192.in-addr.arpa". How do you stop these internal requests going out. Or is this normal?
My caution is that with DNSfilter.com, you pay based on the number of DNS requests made. So not wanting these internal requests to bump up the changes.
eth0 = External
eth1/2 = Local LAN (bridged)
