firewall, allowing access to parts of the network (for hosting a Web or ftp server,
for example). To use, select the host name of a computer on the network from the
“LAN Device” drop-down list (click the down arrow), then click Add. Next, select
a “Category” by clicking the appropriate radio button. In the “Available Rules” list
box, select a game, application, server, etc., then click Add>>. The selected item
appears in the “Applied Rules” list box. Repeat for each item needed
To remove an item from the Applied Rules list, highlight it, then click Remove.
To view an item’s rules (forwarded ports, etc.), highlight it, then click View Rule.
To create a custom set of rules, click the “User” radio button, then click New. The
“Rule Management” screen appears.
