Ok, I think that is the problem, I need to define the IP's as External and Internal. I am guessing (Don't laugh, I am pretty new at this) that the $EXTERNAL var should be my global internet NIC IP and $INTERNAL should be my intranet 192.168.x.x NIC? Also, how does one make any sense out of the packets? This looks pretty Greek to me.

I have having a difficult time getting the rule sets to work. I think, that I don't have the rules set up properly. Do I need to define $INTERNAL and $EXTERNAL as ip/ports somewhere? This is just for my home box. Here is the sample rule I am trying to get to work. alert TCP $EXTERNAL any -> $INTERNAL 80 (msg: "IDS552/web-iis_IIS ISAPI Overflow ida"; dsize: >239; flags: A+; uricontent: ".ida?"; classtype: system-or-info-attempt; reference: arachnids,552;) Thanks for any help, it is greatly appreciated. - Jwatch
