Custom DNS servers leaking?

Hi, reporting another DNS problem, but starting a new thread so as not to hijack the other one that just started.


My BOX 2 is set up in bridge mode behind my ISP-provided residential gateway (modem/router combo). The DNS server on the RG can't be changed. When the firmware upgrade came out, I changed my DNS to 1.1.1.1 right away. However, I'm noticing that when I run tests on dnsleaktest.com, sometimes I get cloudflare and sometimes I get my ISP's DNS servers. There doesn't seem to be any pattern to this, except that usually the first few times I run it, it's my ISP, and then after running it several times I get cloudflare (or google, or any other public DNS I set it to).

    Thomas that is a poor design by the hw designer not following RFC, look at pihole to resolve dns

    Well, I just set the DNS manually on my devices that have that option (comps, tablets, phones). But one big selling point of having the Box 2 is protecting the IoT devices that don't have that option. I can't run pi-hole on a Mac, and I'm not about to go buy a raspberry pi when I just spent $$ on this Box 2 <img class=" data-emoticon="" src="https://us.v-cdn.net/6031943/uploads/ipb_attachments/emoticons/default_laugh.png" title=":lol:" />
