DoS 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.

Options
Respond to
ICMP
The ICMP protocol is used by the "ping" and "traceroute" programs,
and by network monitoring and diagnostic programs.
• 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.
