[Bug 376392] [NEW] Enabling VPN connection in NetworkManager messes up routing table

[Roger Froysaa]

Public bug reported:

Binary package hint: openvpn

When I enable a VPN connection using the NetworkManager, my routing
table gets all messed up (the default gateway is wrong - it worked in
8.10). If I disable the VPN connection it's ok again.

I'm using the network-manager-openvpn and openvpn packages.

The Ubuntu version is 9.04.
Eth0 is the wired NIC which is not used, eth1 is the wireless which is used.
