Why is Freedome changing my DNS settings?

RossSSD

Hi

I use Freedome version 2.45.888.0 on Windows 10 Enterprise build 18363.2212. I use my computer on Ethernet in my office and on Wifi, using Freedome, at external locations. Sometimes, after having used Freedome on Wifi then coming into the office after starting up the computer, the Ethernet connection shows no internet.

I look at the adapter settings and it shows the DNS server has been manually set to either 127.0.0.1 or 0.0.0.0. I've checked all adapter settings in netsh dump. I took screenshot of the IPv4 configuration when the internet works correctly after having used Freedome. I've looked at netsh dump again after the fault has happened but it doesn't show anything different about the routes, interfaces or subinterfaces.

I understand that Freedome uses DNS-over-HTTPS to anonymise DNS queries but if it's going to set Windows's DNS server address to localhost, it should at least set it back after leaving the program. I don't know why 0.0.0.0 would be an option either.

Is this being addressed in a new version of the client?

Kind regards

Hi @RossSSD

Welcome to our Community page. Thank you for your post.

I have consulted with our FREEDOME team.

It should set it to 0.0.0.0 only while VPN is connected/connecting and proper DNS address is set only to FREEDOME adapter (FREEDOMEVPNConnection) to prevent Windows from trying to send DNS through other interfaces. It should restore original DNS address once the VPN is disconnected.

If DNS of real interface is left as 0.0.0.0 even after VPN has been manually disconnected, then we require logs to investigate the issue.

However, it is unclear if the internet is not working or if it just Windows network state information is incorrect. For incorrect state information issue, you may go to this link for support article https://community.f-secure.com/freedome-en/kb/articles/6928-limited-network-availability-warning-shown-with-freedome-vpn

Thank you and stay safe.

Hi

The actual interface's DNS address is set to 0.0.0.0 after Freedome is quit. The support article isn't applicable to the issue I'm having.

Which logs do you need?
