Hi, From what I currently see [here](https://github.com/NetworkManager/NetworkManager/blob/5d9a2d9168dbfc999fabebc09ddffce2503897a6/src/dns/nm-dns-manager.c#L744), NetworkManager always use the same interface from resolvconf point of view. This prevent marking some NetworkManager connection as "private" in "resolvconf.conf". By marking those connections as "private", the DNS servers they advertise would only be queried (if we use a local resolver like dnsmasq) for the "domains / search" they advertise. When I say advertise, this can include the NM connection configuration, DHCP, VPN Plugin, or other). I believe this feature is important because: - it allows being connected to multiple VPNs, and resolving their domain name (might need to add some VRF but that is another subject) - it allows being connected to a VPN without all of our DNS queries going through it Do you think it would be possible to add this feature (maybe even adding a field in nm-settings) ? This is a rather important feature for me, so if you are interested, I am available to help.
