Hi,
I'm a little frustrated on getting snort setup right.  I have my var
HOME_NET [192.168.1.0/24,192.168.2.0/24] and my var EXTERNAL_NET
[!192.168.0.0/16], but for some reason I'm still getting alerts coming
from my own home networks class b address (192.168.0.0/16). I don't care
about my class b, just attacks made toward my two class c networks.

I've tried  var EXTERNAL_NET !192.168.0.0/16
I've tried  var EXTERNAL_NET ![192.168.0.0/16]


any help is appreciated.
thanks,
jamie
