DoS Firewall

Enable DoS	If enabled, DoS (Denial of Service) attacks will be
Firewall	detected and blocked. The default is enabled. It is
	strongly recommended that this setting be left
	enabled.
	Note:
	• A DoS attack does not attempt to steal data or
	damage your PCs, but overloads your Internet
	connection so you can not use it - the service is
	unavailable.
	• This device uses "Stateful Inspection"
	technology. This system can detect situations
	where individual TCP/IP packets are valid, but
	collectively they become a DoS attack.
Firewall	If you wish to adjust the settings used by the DoS
Settings	firewall, click this button to open a sub-window.

Options
Respond to	The ICMP protocol is used by the "ping" and
ICMP	"traceroute" programs, and by network monitoring
	and diagnostic programs.
	• If checked, the Wireless Router will respond to
	ICMP packets received from the Internet.
	• If not checked, ICMP packets from the Internet
	will be ignored. Disabling this option provides a
	slight increase in security.
