I have checked again on Bionic, making sure that the installed systemd actually comes from the bionic-proposed repository, that the behavior according to the test case shown in the initial description of this bug is correct, DNS queries of destinations in the VPN done through the VPN's DNS and DNS queries to public destinations being done through the public DNS.
This works correctly and so the systemd update together with the network-manager update fixes the bug described here. So I am marking this bug as verified in Bionic. ** Tags removed: verification-needed verification-needed-bionic verification-needed-cosmic ** Tags added: verification-done verification-done-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754671 Title: Full-tunnel VPN DNS leakage regression To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/1754671/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
