Figure 53: Security Screen
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.
If checked, the Wireless Router will respond to ICMP packets
received from the Internet.
If not checked, ICMP packets from the Internet will be ignored.
Disabling this option provides a slight increase in security.
