procedure on how to use this feature.
Groups and Hosts. You can apply these rules selectively to groups of PCs to reduce the
outbound or inbound traffic. The Network Database is an automatically-maintained list of all
known PCs and network devices. PCs and devices become known by the following methods:
• DHCP Client Request – By default, the DHCP server in this Router is enabled, and will accept
and respond to DHCP client requests from PCs and other network devices. These requests also
generate an entry in the Network Database. Because of this, leaving the DHCP Server feature
(on the LAN screen) enabled is strongly recommended.
• Scanning the Network – The local network is scanned using standard methods such as ARP.
This will detect active devices which are not DHCP clients. However, sometimes the name of
the PC or device cannot be accurately determined, and will be shown as Unknown.
• Manual Entry—You can manually enter information about a device.
See "Managing Groups and Hosts" on page 7-4
Schedule. If you have set firewall rules on the Rules screen, you can configure three different
schedules (i.e., schedule 1, schedule 2, and schedule 3) for when a rule is to be applied. Once a
schedule is configured, it affects all Rules that use this schedule. You specify the days of the week
and time of day for each schedule.

Block Sites
If you want to reduce traffic by preventing access to certain sites on the Internet, you can use the
