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 Clien t Requ es t – 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 b e accurately determined, and will be shown as Unknown.
See “Managing Groups and Hosts (LAN Grou ps)” on page 3-6 for the procedure on how to use
this feature.
