Firewall

Enable DoS	If enabled, DoS (Denial of Service) attacks will be detected and
	blocked. The default is enabled. It is strongly recommended that this
Firewall
	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 cannot use it - the
	service is unavailable.
	∙ The SpeedStream Powerline Wireless Router uses "Stateful
	Inspection" technology. This system can detect situations where
	individual TCP/IP packets are valid, but collectively they become
	a DoS attack.
Threshold	This setting affects the number of "half-open" connections allowed.
	∙ A "half-open" connection arises when a remote client contacts the
	Server with a connection request, but then does not reply to the
	Server's response.
	∙ While the optimum number of "half-open" connections allowed
	(the "Threshold") depends on many factors, the most important
	factor is the available bandwidth of your Internet connection.
	∙ Select the setting to match the bandwidth of your Internet connec-
	tion.
