Firewall
Enable DoS
Firewall
Threshold
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.
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
connection.
