ANSWERED DNS Leak on Mac with Wireguard

[misamarumaru 0]

I recently bought a new Mac and rather than restoring from a backup as I normally do, I thought I'd set everything up fresh and have a clean to start to everything. I was surprised to see that after installing the official Wireguard client and creating a config through the AVPN config generator that IPLeak reported by machine using my ISP's DNS. Wireguard was using the VPN servers IP addresses correctly.

Similar happens at home, where IPLeak shows my DNS as being managed by Cloudflare, which is what I have my router set to use as a default rather than my ISP's DNS.

I know this isn't a problem if I use Eddie, but I love the basic simplicity of the Wireguard app and would prefer to install as few applications as possible now I'm on a clean setup. If anyone can offer a suggestion to force my Mac to always use AirVPN's internal DNS that'd be really appreciated. Thanks.

EDIT: I checked Wireguard's tunnel manager when the VPN was active and it shows the DNS being used is '10.128.0.1', which I believe is correct, but that's not what IPLeak sees. Presumably my Mac is ignoring that and defaulting to the default DNS.

I may have solved my own problem. I hadn't noticed that Tailscale was also active and defaulting to use its own DNS. Disabling that DNS immediately restored AirVPN's DNS servers when checked against IPLeak.
