Quoting Sascha Hintz <sascha.hintz () gmx net>:

I would like to disable our VPN Network in HOME_NET. Because i dont  
want have attacker alerts from this network.

Can you help me ?

maybe.  here is what you *cannot* do:  use a negation in the HOME_NET  
var.  Things like this will not work:
   var HOME_NET [10.3.0.0/16,!10.3.4.0/24]
You cannot negate an address range that is a proper subset of an  
already defined address range.  We've all tried it.  It won't fly.

you will have to do something like this to enumerate what *is* in home_net:

   var HOME_NET [10.3.1.0/24,10.3.2.0/24,10.3.3.0/24,10.3.5.0/24]
