DoS Defense, Value is Disable, Enable Icmp Flood | Epson 3300

DoS Defense	Enables or disables the DoS Defense function. The default
	value is Disable.

Enable SYN Flood Defense Activates the SYN flood defense function. If the amount of TCP SYN packets from the Internet exceeds the user-defined threshold value, the router will be forced to randomly discard the subsequent TCP SYN packets within the user-defined timeout period. The default setting for threshold and timeout are 300 packets per second and 10 seconds, respectively.

Enable UDP Flood Defense Activates the UDP flood defense function. If the amount of UDP packets from the Internet exceeds the user-defined threshold value, the router will be forced to randomly discard the subsequent UDP packets within the user-defined timeout period. The default setting for threshold and timeout are 300 packets per second and 10 seconds, respectively.

Enable ICMP Flood	Activates the ICMP flood defense function. If the amount of
Defense	ICMP echo requests from the Internet exceeds the
	user-defined threshold value, the router will discard the
	subsequent echo requests within the user-defined timeout
	period. The default setting for threshold and timeout are 300
	packets per second and 10 seconds, respectively.

Enable Port Scan Detection Activates the Port Scan detection function. Port scan sends packets with different port numbers to find available services, which respond. The router will identify it and report a warning message if the port scanning rate in packets per second exceeds the user-defined threshold value. The default threshold is 300 pps (packets per second).
