You can secure your network by creating and applying rules that the uses to
selectively block and allow inbound and outbound Internet traffic. You then specify
how and to what devices the rules apply. To do so, you must define the following:
• Services or traffic types (examples: web browsing, VoIP, other standard
services and also custom services that you define) that the router should
allow or block.
• Direction for the traffic by specifying the source and destination of traffic;
this is done by specifying the "From Zone" (LAN/WAN/DMZ) and "To Zone"
(LAN/WAN/DMZ).
• Schedules as to when the router should apply rules.
• Keywords (in a domain name or on a URL of a web page) that the router
should allow or block.
• Rules for allowing or blocking inbound and outbound Internet traffic for
specified services on specified schedules.
• MAC addresses of devices whose inbound access to your network the
router should block.
• Port triggers that signal the router to allow or block access to specified
services as defined by port number.
• Reports and alerts that you want the router to send to you.
You can, for example, establish restricted-access policies based on time-of-day,
web addresses, and web address keywords. You can block Internet access by
applications and services on the LAN, such as chat rooms or games. You can block
just certain groups of PCs on your network from being accessed by the WAN or
public DMZ network.
