Managing Groups and Hosts (LAN Groups)
The Known PCs and Devices table on the Groups and Hosts screen contains a list of all known
PCs and network devices, as well as hosts, that are assigned dynamic IP addresses by this router.
Collectively, these entries make up the Network Database. The Network Database is created in two
ways:
• 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.
Note: Additional IP addresses cannot be configured in the DHCP server. The hosts on the
secondary subnets must be manually configured with the IP addresses, gateway IP
and DNS server IPs.
Warning: Make sure the secondary IP addresses are different from the LAN, WAN,
DMZ, and any other subnet attached to this router.
For example:
WAN1 IP address: 10.0.0.1 with subnet 255.0.0.0
WAN2 IP address: 20.0.0.1 with subnet 255.0.0.0
DMZ IP address: 192.168.10.1 with subnet 255.255.255.0
LAN IP address: 192.168.1.1 with subnet 255.255.255.0
Secondary LAN IP: 192.168.20.1 with subnet 255.255.255.0
