The Firewall will always block DoS (Denial of Service) attacks. 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.
As well, you can use this screen to create Firewall rules to block or allow specific traffic. This feature is for Advanced Administrators only! Incorrect configuration will cause serious problems.
This lists all existing rules. If you have not defined any rules, the table will be empty.

To make changes to an existing rule:
Specifying a Default DMZ Server allows you to set up a computer or server that is available to anyone on the Internet for services that you haven't defined. There are security issues with doing this, so only do this if you'll willing to risk open access. If you do not assign a Default DMZ Server, the router discards any undefined service request.
To assign a computer or server to be a DMZ server:
To remove the DMZ server:
If you want the router to respond to a 'ping' from the Internet, click the Respond to Ping on Internet WAN Port check box. This can be used as a diagnostic tool. Again, like the DMZ server, this can be a security problem. You shouldn't check this box unless you have a specific reason to do so.
