Rules Help

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.

Rule Table

This lists all existing rules. If you have not defined any rules, the table will be empty.

To create a new rule:

  1. Click the "Add" button. (It does not matter which radio button is selected)
  2. The "Add Rule" screen will be displayed. This screen has its own help file.

To make changes to an existing rule:

  1. Click the radio button next to an row in the table.
  2. Click the button for the desired actions:

Default DMZ Server

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:

  1. Type the IP address for that server.
  2. Click Add DMZ.
  3. Click Apply.

To remove the DMZ server:

  1. Click Delete DMZ.

Respond to Ping on Internet WAN Port

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.
