[Pkg-utopia-maintainers] Bug#838907: network-manager-openvpn: Network Manager adds weird routes after connecting to OpenVPN

[Jan Korbel]

Hello.

Problem still exists in up-to-date unstable.

OpenVPN-in-OpenVPN is not working with Network manager. It works w/o Network manager
(if second tunnel started by openvpn init script).

First tunnel is "redirect-gateway def1", second without gw redirect.

Routes:

1. non working
nm - first tunnel to public_srv1
nm - second tunnel to public_srv2
