Hi, I had the same problem on Linux Mint 18.1 First time i start openvpn connexion all is ok. But if i stop it and start again via networkmanager, there are no DNS (but ping ip is ok). A reboot of the computer make dns come back.
Or i found a temporary solution, modify the file /etc/NetworkManager/NetworkManager.conf and comment the line #dns=dnsmasq After this i stop / start many times openvpn connexion via network-manager and it works well. -- 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/1675519 Title: Network Manager w/ dnsmasq Dies when VPN-ing Status in network-manager package in Ubuntu: Triaged Bug description: Hello. Within the past week or so, a new bug has cropped up on Network Manager on 16.04. When Network Manager on 16.04 is configured to use dnsmasq and not systemd-resolved, one is expecting VPN DNS servers to be properly set and dnsmasq to properly route DNS requests to the Internet. However, when connecting to my OpenVPN connection, dnsmasq now fails extremely hard and no longer replies or routes data for DNS requests properly. This results in me having to use a fail-over workaround of enforcing resolvconf to use my local `bind9` instance on my own system for DNS, which is configured to route to Google for DNS requests. This, however, prohibits me from using my own DNS on my VPN connect, which are on the remote location and serve internal ranges and domains that I should be permitted to access. Given these issues, with `dnsmasq` just outright exploding in our faces and no longer being usable for DNS request routing over the VPN, I'm not even sure we can consider VPN DNS as a viable option anymore with 16.04. Note that this is only *very* recently a problem within the past few weeks, and I can't find any updates which would have impacted this.
