Enable DoS

If enabled, DoS (Denial of Service) attacks will be detected and

Firewall

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.

 

 

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.
