I am seeing similar messages in my snort logs. I hope it is only spoofing
and not that my machine has been compromised.

I found out what was the cause with my machine.
When someone made a connection thru the firewall to surf the web these 
messages were generated because I removed a few ports from the pre-prosessor. 
I removed port 80 and 443 for instance.
Now I added them back and the logs are quit now. (except for a real portscan)

Hope this helps
