Firewall

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.
