Jan 22, 2020 · It is not secure since the external DNS servers (specified for your VPN connection) can potentially see your DNS traffic (the leak of your DNS requests). You can disable the SMHNR in Windows 10 via the GPO: Computer Configuration -> Administrative Templates -> Network -> DNS Client-> Turn off smart multi-homed name resolution = Enabled.

The only problem is that the DNS Resolver does not work. No DNS is resolved, it just returns " ** server can't find xxx.com: SERVFAIL ". This happens whatever combination of outgoing interfaces I choose (I tried MULLVAD only), except for WAN only; but if I set WAN as outgoing interface, then the DNS traffic does not go trough the VPN and I have
