DHCP Client
(Available in Router or SOHO Router mode only.) Displays
the device’s WAN IP address, netmask, DNS servers, and
gateway while the device is operating as a DHCP client of
an external DHCP server.
Interface Displays the interface that connects to the
WAN.
IP Address Displays the IP address assigned by an
external DHCP server connected to the WAN interface.
If an external DHCP server is not found, the IP address
will use the DHCP Fallback IP defined in the WAN Network
Settings. See “WAN Network Settings” on page 32 for
additional details.
Netmask Displays the Netmask assigned by an external
DHCP server connected to the WAN interface. If an
external DHCP server is not found, the IP address will use
the DHCP Fallback Netmask defined in the WAN Network
Settings. See “WAN Network Settings” on page 32 for
additional details.
Gateway Displays the gateway address assigned by an
external DHCP server connected to the WAN interface.
Primary/Secondary DNS IP The Domain Name System
(DNS) is an Internet “phone book” that translates domain

DHCP server that assigns the WAN IP address to the
device.
Domain Displays the domain name.
Total Lease Time Shows the total time (validity) of the
leased IP address assigned by the external DHCP server.

is important to have unique IP addresses for each MAC
address or else there will be ambiguous routes on the
network.
IP Address Displays the IP address assigned to a network
device.
MAC Address Displays the MAC address of the device.
Interface Displays the interface that connects to the
device.

forward packets only to the specified port of the device,
eliminating redundant copies and transmits.
Aging Timer Displays aging time for each address entry
(in seconds). After a specific timeout, if the device has not
seen a packet coming from a listed address, it will delete
that address from the Bridge Table.
