I have configured the router with the dns settings. If I run the leak test on the computer #1, it says I am using cleanbrowsing. However, computer #2 leak test returns our ISP server, and, if I turn off the cellular, so my phone is just using the router, leak test returns our ISP server, not cleanbrowsing. Any suggestions on why it works on one machine and not the others?
Also, does dnsleaktest.com work on ipv6? Is there a test to see if I am also filtering on ipv6? I know I have connectivity to both ipv4 and ipv6.
