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.
