I have the same problem. After establishing the connection I can ping all IP's, even the DNS server in the VPN network. But DNS resolve for servers in the VPN network does not work. I have even set the DNS servers IP and the domains to resolve in the network managers VPN configuration (in IPv4 settings) and set it to addresses only. It is still not resolving any VPN network addresses. Global addresses are resolved.
That was working in older versions of Ubuntu. I cannot tell when this was broken because I do not regularily use VPN, but the configuration was there and working in some previous release. I have upgraded this machine now for quite some years. Now in 16.04 it is broken. On a Windows machine that I tested it is still working. -- 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/1211110 Title: network manager openvpn dns push data not updating system DNS addresses Status in network-manager package in Ubuntu: Incomplete Status in openvpn package in Ubuntu: Incomplete Bug description: [Triage Notes] This bug can no longer make progress. Please see comment 50 for details and further instructions. [Original Description] When IPv4 Method is set to Automatic VPN, DNS address recieved from OpenVPN server do not update resolv.conf. This can be achieved when using a standard openvpn config file by adding the lines: script-security 2 up /etc/openvpn/update-resolv-conf down /etc/openvpn/update-resolv-conf In Network-manager there seems to be no option to run connection specific scripts and the DNS data from the server is ignored.
