How to route my traffic through the VPN

[manmad dvb12er]

Thanks a lot for your quick replay.
Regards the script, I forgot to mention that I used it from the command line.
Anyway, the "Use this connection only for resources on its network" is not set.
How can I change the default route?
I tried:
sudo route add -net 0.0.0.0  vpn0
But it didn't worked: I had no internet access. Am I doing something wrong?
Thanks.
