In this section you can specify the days and times of the week when certain client devices are denied access to the Internet. You can also restrict certain services, such as instant messaging or games, by specifying the ports associated with those services. For example, you can deny a specific computer access to the Internet between 10:00PM and 5:00PM during the week and between 12:00AM and 8:00AM on weekends.
This section is where you create “holes” in the firewall to allow certain services, such as instant messaging and games, to communicate over the Internet.
If you are creating an entry for a particular application, its documentation will provide information about the settings you need to enter here.
Users will typically not need to use this section. It’s for directing certain inbound packets to specific ports on specific client devices. For example, you might use this if you host a Web server on your network.
