Comment 13 for bug 1211110

Whether this is a bug or feature request, I don't know, but to be sure, it is possible to do this with a .conf file and "sudo service openvpn start" and not possible to do it via network-manager-openvpn (unless you count disabling dnsmasq--I'm curious what side effects this has). As described in the original report, I have verified that these lines in a .conf file allow the server to configure DNS (as long as the server pushes 3 or more DNS servers):

  script-security 2
  up /etc/openvpn/update-resolv-conf
  down /etc/openvpn/update-resolv-conf

but network-manager-openvpn does not support the 'up' and 'down'.

This same issue was addressed here:
