Assuming you have correctly defined the variables in the /etc/snort.conf
file paying close attention to the $HOME_NET and $EXTERNAL_NET variables
you might want to consider a BPF filter on your input.

I am new to IDS and have just set up snort on a ubuntu host. It has worked
well except for the fact that I am getting some false positivies from local
traffic on the network. I have been trying to find the solution on snort's
forums but the site seems to be going up and down randomly. I want to set a
rule in order to suppress/ignore local network traffic for 192.168.1.0/24.
I know this can be done in the /etc/threshold.conf file but have not been
able to do so successfully. Can someone be so kind as to post their
threshold.conf file or guide me through the process?
Thanks,
Blake
