Adding auto tap0 iface tap0 inet dhcp
to /etc/network/interfaces causes startup to "pause 60 second for network". If I add tap0 using sudo ip tuntap add mode tap tap0 then nm-openvpn tries to configure a new tap device (tap1) Also, I tried disabling tap in the nm-openvpn config, and the same thing happens for tun0 Oct 27 21:43:01 havet NetworkManager[949]: <warn> /sys/devices/virtual/net/tun0: couldn't determine device driver; ignoring...

I am able to connect when using the 'regular' OpenVPN client and a config file, but not through NM with a similar config. From my investigations so far, it seems that the /sys/devices/virtual/net/tap0 device doesn't get created, but I am unable to work out why that is happening. I tried putting apparmor into complain mode to make sure it wasn't a problem with that. I pasted what I believe is the relevant part of syslog below (edited out identifiable information). Can anyone help me with some pointers as to how to troubleshoot this? Best Regards Oct 25 13:38:22 havet NetworkManager[952]: <info> Starting VPN service 'openvpn'...
