More on home_net and external_net

[Gisli Helgason <Gisli () gltrade co uk>]

Hi all
 
I would like to configure my rules to log and alert in the following way.
 
home > home
external > home
NOT home > external
 
Is there any way to configure my snort.conf to do that.
 
Thanks, for all your help in the past.
 
Gisli.
