You shouldn't need (but it shouldn't hurt) the set of brackets around the
network address, as you're only using one network address.  So: 

    var HOME_NET 10.0.0.0/8
    var EXTERNAL_NET !$HOME_NET

will work, or just: 

    var $EXTERNAL_NET !10.0.0.0/8

Cheers!

Subject: [Snort-users] Home and External networks

When defining the network definitions in snort.conf, does anyone know if
the following syntax would be usable.

var $EXTERNAL_NET ![10.0.0.0/8]

I am trying to say everything but 10.0.0.0/8 is an external network like
when configuring an actual alert rule.


Thanks,

Fred
