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.
The Broadband Router uses "Stateful Inspection" technology. This
system can detect situations where individual TCP/IP packets are
valid, but collectively they become a DoS attack.
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.
