This feature enables you to make and view the current Dynamic Host
Configuration Protocol (DHCP) settings for your router. DHCP is a TCP/IP
service protocol to provide dynamic leasing of IP addresses and other
configuration information to client hosts on the network. Your router can
perform as a DHCP server with central management of your IP address pool for
simple and safe TCP/IP configuration and IP address conservation. When DHCP
is combined with Network Address Translation (NAT), your router adds a
measure of security to your network through the leasing and concealment of
private IP addresses behind one unique public IP address. These private IP
addresses also help avoid the costs associated with obtaining additional public IP
addresses to support a growing network.
To activate DHCP, select Enable from the New Setting list and click on the
Apply button. Conversely, selecting Disable will deactivate DHCP.
W ith DHCP, all IP addresses are assigned to network clients from a pool. The IP
Addresses Pool Setting section provides fields for defining the range of IP
addresses included in your pool. The fields under Current Setting display the
current range of the IP Address pool. Use the fields under the New Setting label
to define a new range of IP addresses for the pool. Click on the Apply button to
establish the new IP addresses pool settings.
The Current DHCP Leases List shows the network clients that are currently
leasing their IP addresses from the pool. From left to right, the following
information is presented on each row:
•Client IP: Displays the leased IP address assigned to that specific
client.
•State: Indicates whether the IP address is enabled or disabled.
•Host Name: Displays the name of the host leasing that specific IP
address.
•Expires (mm/dd/yy): Displays the date when the IP address lease
will expire. At that time (if not before), the leased IP address will be
freed for re-assignment, and the network cl ient w ill need to request a
new IP address from the router.
After DHCP settings have been completed, click on the Back to Home button to
return to the home screen.
