Public bug reported: I'm using Ubuntu 16.04, connected to the same network by both Ethernet and Wi-Fi. When I query dnsmasq by running:
dig +short chaos txt servers.bind I see only one set of DNS servers (one IPv4, one IPv6); not sure if it's NetworkManager or dnsmasq that is de-duping the servers from both connections. When I connect to an OpenVPN connection (configured through NM, IPv4-only, with no split-tunnelling) and query dnsmasq again, I see that the VPN DNS server is present, but the local IPv4 DNS server is also still used (dnsmasq reports two IPv4 servers, one IPv6 server). (I filed bug #1615343 regarding the local IPv6 DNS server not being removed.) ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1615347 Title: Local DNS server not removed when connected to OpenVPN network, when connected by both Ethernet and Wi-Fi Status in network-manager package in Ubuntu: New Bug description: I'm using Ubuntu 16.04, connected to the same network by both Ethernet and Wi-Fi.
