Hi, when you use openvpn directly, you configure all it's options explicitly, either via command line or .ovpn configration file. When you use nm-openvpn plugin, you create a "connection" (profile) via one of the client tools (nm-connection-editor, nmcli) or via import from ovpn file. In any case, this does not understand every option, because some are not implemented and others don't make sense in the context of NetworkManager (e.g. running as server). Also, NM wants to configure IP addressing and DNS itself, it does not allow openvpn to do that. Then, nm-openvpn spawns openvpn with command line arguments based on the connection. openvpn doesn't communitcate via D-Bus. It gets executed by nm-openvpn-service with command line options, and it calls back to NM via --up /usr/libexec/nm-openvpn-service-openvpn-helper If something doesn't work, then there is no other way then to open a bug about it and fix it in nm-openvpn/NetworkManager. That said, import of ovpn file is supposed to just work. What didn't work for you there? Thomas
