Firewall

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 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.
