Title:
  network-manager-openvpn leaks while connecting

Status in network-manager package in Ubuntu:
  Confirmed
Status in network-manager-openvpn package in Ubuntu:
  Confirmed

Bug description:
  Network-manager-openvpn leaks while connecting. Maybe that is intended
  behavior when activating a VPN-connection manually but it also **leaks
  when "Automatically connect to VPN when using this connection" is
  checked**.

  By "leaking" I mean that there are packages leaving/entering the
  machine without passing through the VPN.

  Verfied the following way:
  1. Set up a VPN that connects via UDP (verify it).
  2. Configure a Wifi network that blocks UDP, check "Automatically connect to VPN..." and preselect your special VPN.
  3. Connect to that newly configured Wifi network.
  4. Browse the internet.

  Another way:
  1. Type "traceroute ubuntu.com" into a terminal but don't press enter.
  2. Start the Wifi network that uses the "Automatically connect... VPN..." feature.
  3. Go back to the terminal press enter.
  4. After the VPN has connected repeat the command.
  5. Compare the first hop of the traceroute results.

  I consider this a security bug since it endangers users relying on a
  working/leak-free VPN.
