The macOS is restoring the default DNS configuration
Bug report
Describe your environment
- Connect VPN (any protocol) 1.1 (not obligatory step) We can also set custom DNS or enable AntiTracker
- Check OS DNS config - DNS is OK
- Disable WiFi
- Enable WIFI (for OpenVPN connection: enable WiFi in less than 30 seconds after wifi was disabled)
- Check OS DNS
Expected: OS is using IVPN DNS (or custom DNS, if defined)
Observed: OS is using the default DNS server (non-IVPN configured). If the IVPN firewall is enabled -> user is unable to use web browsers because the default DNS is blocked by the firewall.
Possible solution
The app has to monitor all changes to the DNS configuration on a computer and fix it (when required)
@gorkapernas can you, please, check also https://github.com/ivpn/desktop-app/issues/202 ? I believe, it is the same issue.
Verified fixed on v3.9.35, firstly I reproduced the issue on a previous version by following the steps provided in the ticket, but in the newest beta version, the issue no longer occurs, every time I enable WIFI or switch networks, the OS uses the IVPN DNS as expected.
Regarding #202, there aren't many details, but it looks like it's the same issue, I was able to reproduce the problem by switching networks, but with the fix implemented on this ticket, the issue has been solved.
