Bug 497123

Description of problem:
When attempting to use the openvpn as the default route for traffic, the error:

Apr 22 08:01:22 janos-wks NetworkManager: <WARN>  nm_system_replace_default_ip4_route_vpn(): (tun0): failed to set IPv4 default route (pass #2): -3

apperars in /var/log/messages and no route is set to the vpn (not even a connected route).

with the vpn connected (172.22.13.0/24 is the vpn subnet):
[root@janos-wks ~]# ip r
75.131.70.10 via 172.22.20.1 dev eth0  proto static 
172.22.20.0/24 dev eth0  proto kernel  scope link  src 172.22.20.40  metric 1 
192.168.122.0/24 dev virbr0  proto kernel  scope link  src 192.168.122.1 
default via 172.22.20.1 dev eth0  proto static

The routes can be set manually, using route add after connecting.

interestingly enough if you push static routes in the openvpn server these work fine.
With a pushed route and the vpn connected:
[root@janos-wks ~]# ip r
75.131.70.10 via 172.22.20.1 dev eth0  proto static 
172.22.13.1 dev tun0  proto static  scope link 
172.22.20.0/24 via 172.22.13.1 dev tun0  proto static 
172.22.20.0/24 dev eth0  proto kernel  scope link  src 172.22.20.40  metric 1 
172.22.42.0/24 via 172.22.13.1 dev tun0  proto static 
192.168.122.0/24 dev virbr0  proto kernel  scope link  src 192.168.122.1 
default via 172.22.13.1 dev tun0  proto static 

Unfortunately a pushed route does not accomplish our needs for the vpn (too many networks to push).

Version-Release number of selected component (if applicable):
NetworkManager-0.7.0.99-5.git20090326.fc10.x86_64
NetworkManager-glib-0.7.0.99-5.git20090326.fc10.x86_64
NetworkManager-openvpn-0.7.0.99-1.fc10.x86_64
NetworkManager-gnome-0.7.0.99-5.git20090326.fc10.x86_64


How reproducible:
Everytime, on multiple Fedora 10 computers (at this version, the previous version of NetworkManager still works fine)

Steps to Reproduce:
1. Create an openvpn connection to the server in networkmanager
2. Set the openvpn server to --push redirect-gateway
3. Connect
or
1. Create an openvpn connection to the server in networkmanager
2. Set the openvpn client to "ignore obtained routes" (client side option that redirects the gateway)
3. Connect
  
Actual results:
No routes defined after a successful vpn connection.

Expected results:
a redirected default gateway so that all traffic goes through the vpn.
