Ah-hah - CLICK! So, can I have multiple comma seperated blocks - ie;

![excludes_here],[includes_here]

IE, if there is a machine in the 1.1.1.0 range that I want to log, how do I log it? 

Rgds,

That's normal :

Example : box 1.1.1.4

       !1.1.1.0         !172.16.16.0/24
         |                 |
but    False or Right or Right = Right
                 |
              !172.16.0.0/24

when snort tests !172.16.0.0/24 and !172.16.16.0/24, the IP 1.1.1.x make it right so your 1.1.1.x box gets considered 
as external_net.
