Case II:
This is the case where McAfee Firewall is activated while blocking the Inbound ICMP Echo request packets. Generally the results similar to case I were anticipated. But the system became non-responsive after 2.5 minutes of launching the attack with 100 Mbps of Ping attack traffic in the Fast Ethernet medium. System had to be restarted and the load of the attack traffic was reduced. To understand the system behavior the attack traffic was reduced to 1 Mbps. It was found that even with 1 Mbps of Ping attack traffic the system froze, and was not responding after 3 hours of launching the attack.
