Mullvad Wireguard connecting fine but when modifying the config DNS to use one of Mullvad Adblock dns servers results in no internet connectivity.
Using the same config and dns server in Wireguard app on iOS and internet connectivity is fine with Adblock.
This link provides the dns servers to use.
I am using the beryl travel router and have also updated to the latest 3.211 beta (also didn’t work on 3.203 stable).
I am using the Gl.iNet iOS app to connect to multiple Mullvad Wireguard servers across different locations. Default dns server works fine but as soon as I modify the dns per the above url there in no internet connectivity. I thought that maybe that it just won’t work, but applying the Adblock dns server on Wireguard iOS app manual config works with no issues. Appears that the issue is isolated to the beryl or glinet devices.
