I suggest that you address your question to the appropriate Snort mailing list found here:

https://www.snort.org/community

The bug is in your HOME_NET line in your snort.conf.  It's not in the rule.

I've bought several vehicles there from Sheila, and I have nothing but fantastic things to say about her. If you are looking to purchase a vehicle, go to her. That being said, the maintenance department... I went in for an oil change and my check engine light was on, and they wouldn't even see why. They don't have an EC2 reading machine in the oil change bay? Come on!
