Hi,

I have a strange problem with establishing VPN network after an upgrade from 11.4 to 11.11. I'm using gnome network-manager
NM applet says it successfully established connection, but:
- I can't access remote network
- tun device is not visible in ifconfig, though it's enabled according to e.g.: firestarter.
- routing table doesn't contain any entries that would put the traffic to remote network
Here's the log:
