Enable DoS 
Firewall 
If enabled, DoS (Denial of Service) attacks will be 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 cannot 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.
