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.
•
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.
