Start Port	For a range of ports, this will be the first port in the range. For a single port
	enter the port number.

	packets destined to that IP address.

To delete or modify an existing rule, select the index number and click the action button for Delete or Modify. Clicking on the Clear button will set the variables to the blank or default setting.

Each new rule that is added will appear in the entry table at the top of the web page. When you have configured all the rules you want to use, click on the Apply button. You can save and reboot the system now, or continue to configure the Router.
