LAN Ports and Attached Devices

Known PCs and Devices
The Known PCs and Devices table contains a table of all IP devices that the firewall has
discovered on the local network. This screen is accessible from the Administration main menu
and the LAN Groups submenu. The Groups and Hosts screen will display showing the Known
PCs and Devices table shown below:.
Figure 6-7
The Groups and Hosts database is an automatically-maintained list of all known PCs and network
devices. PCs and devices become known by the following methods:
• DHCP Client Requests. 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.
