Advanced > Firewall
The Firewall Configuration menu
allows the Router to enforce
specific predefined policies
intended to protect against
certain common types of
attacks. There are two general
types of protection (DoS, Port
Scan) that can be enabled on
the Router, as well as filtering
for specific packet types
sometimes used by hackers.
You can choose to Enable or
Disable protection against a
customized basket of attack and
scan types. To enable DoS
Protection or Port Scan
Protection, select the Enable
radio button for the protection
type and click in the selection
boxes for the various types of
protection listed under each.
When DoS, Port Scan, or Service Filtering Protection is enabled, it will create a
firewall policy to protect your network against the following:
