I can confirm this bug, it has also been reported to the NetworkManager bugtracker: https://bugzilla.gnome.org/show_bug.cgi?id=629807
The problem seems to be that NetworkManager and/or OpenVPN are unable to set up a tun interface with a subnet topology. The only working alternatives are a tun interface with a point-to-point topology and a tap device with a subnet topology. However, if the VPN configuration only allows a tun interface with a subnet topology, the network is unusable for NM users. ** Bug watch added: GNOME Bug Tracker #629807 https://bugzilla.gnome.org/show_bug.cgi?id=629807 -- Openvpn: Connection succesful only when using TAP device https://bugs.launchpad.net/bugs/610361 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
