Chris, if you have firewall software installed on the same system as your 
IDS, then the FW won't affect what your IDS can see.  Snort uses libpcap, 
which is lower on the TCP stack than your FW, so it will see packets before 
they get dropped.

Also, please be sure to check the FAQs and the mailing list archives for
information before posting to the list in the future.  This question has
been answered a few times already in the past.

Cheers - Erick
