Add route exception in NetworkManager vpn

[Erwan David <erwan@rail.eu.org>]

Hi,

I use a vpn with network manager which routes everything through it.
I'd like to add some exceptions for local or not so local ressources 
that cannot be reached through the VPN.
The ideal situation would be to be able to give as gateway for those 
routes "the default gateway before the VPN was up".
Is there a way to do this ?

It may be through a dispatcher script at vpn-preup time, but I'm not 
sure by reading the doc if the routes have been changed at that time or not.



Thank you
