How to VPN on demand Mac OS X?

I'm trying to configure the Snow Leopard's VPN on demand service without success

I've tried the following domain+configuration pairs but none of them have worked:

domain.net default
*.domain.net default

My goal is that each time I go to www.domain.net with Safari, ssh server1.domain.net or everything else on this domain.net the connection will be established trough the VPN !

I've tried plenty of different configs but it has never worked so far...

As I discovered after some testing: VPN on demand on OS X doesn't work with configuration "Default"!

Solution:

Add a minimum one named configuration on the VPN interface which you use for connecting. Then everything works fine - it's simple like that!

Apparently this works only if you're using certificate-based authentication.

What is VPN on demand, and how do I get it to work with iOS?

The VPN connection is made whenever the device tries to connect to certain domains. Specific apps don't need to do anything; as soon as they try to access such a server the VPN connection is initiated.
