Disabling Port Scan and DoS Protection
The DoS firewall protects your network and computers against attacks and intrusions. A stateful

malformed, oversized, or out-of-sequence packets. The firewall should be disabled only in special 
circumstances, such as when you are troubleshooting application issues.
