I also experience this problem and it is not limited to NetworkManager configuration with dnsmaq. This bug appears also when NetworkManager is managing /etc/resolv.conf directly.
Additional info:
I've tested to deny access to 1-st and 2-nd NS servers from the machine running OpenVPS server and the result was that the local NS server was used, despite the fact that the checkbox 'Use this connection only for resources on its network' is unchecked. This leads to DNS leak if the first 2 NS servers could not be reached.
I've filled a bug in redhat's bugzilla as I was unable to find this in the beginning. https:/ /bugzilla. redhat. com/show_ bug.cgi? id=1322932
