A few questions

["Newbie" <h8u9myo02 () sneakemail com>]

Hi 
 
I have a few questions regarding Snort, which I currently run on Windows just as a monitoring tool.
 
I am not on a network, I simply have my PC and router as a home configuration. However I get a lot of false negatives 
where the error relates to my router. How can I configure HOME_NET to therefore include any IPs that begin with 123.123 
etc? Currently it is setup IP/32 – what would the new one be?
 
Secondly, because I am using a home PC/router, I am not sure the flow:to_server is relevant for me. These commands also 
include major anti-trojan rules which don’t seem to therefore work for my PC setup. Can I simply remove these commands 
if I am not on a server?
 
And finally – a more simple question, apart from a Snort equivalent with some more graphs, what more security features 
do all these wiz-bang systems you pay thousands for actually include?
 
As you can tell – am a newbie and just have a few queries.
 
Thanks for your help
