Hereís another option which is similar, but a slightly different approach. Itís working well for me, but I would certainly be interested in feedback from others.

When setting up my system for DNS, I had two main goals:
  • Only use a DNS server I specify (lots of devices ignore the DNS servers you specified in the Interface Configuration)
  • Send all DNS requests through one of my Tunnel VPNs, even if the device doesnít use the VPN tunnel for traffic. I have some streaming devices that go through a VPN tunnel and some that donít, but I wanted all DNS lookups to go through a tunnel.


Using the DNS override did not work for me - the DNS requests didnít go through the VPN tunnel of choice.

Interestingly, even though I donít use my VPN providers DNS servers, it doesnít detect a leak since all of the DNS traffic is going through the VPN tunnel before it hits the DNS server I specify
