Don't Alert any syn-scan!
- 
 Hi everybody, 
 I want to test the ids feature and I run this command:sudo nmap -Pn -sS x.y.z.tI did not get any alert but when I run this command: sudo nmap -Pn -O -A x.y.z.tI could see an alert by my IP on the Services/Snort/Alerts! Why did not pfSense alert the simple syn-scan?

 Did you enable Port scan detection? General preprocessor settings section –> enable 'Portscan Detection'
