DHCP
DHCP (Dynamic Host Configuration Protocol), is a TCP/IP service protocol that provides dynamic leasing of IP
addresses and other configuration information to client hosts on the network. The router can act as a DHCP
server, automatically providing a suitable IP address and related information to each computer when the
computer boots up.
To configure DHCP:
1. Click DHCP in the left navigation pane of the Router Information window. This displays the DHCP
Configuration page. This page shows the current settings as well as provides a means to change the
current settings.
2. To change the server status, select Enable or Disable from LAN DHCP Server Status. Disabled, the
router will not act as a DHCP server.
3. To change the start and ending address range of the IP address pool, enter the starting address in First IP
Address and the ending address in Last IP Address.
4. Click Apply.
Note that a list of network clients that are currently leasing their IP addresses from the pool are shown in
Current DHCP Leases List: From left to right, the following information is presented for each client:
• Client IP: The leased IP address assigned to the specific client.
• State: Whether the IP address is enabled or disabled.
• Host Name: Name of the host leasing the specific IP address.
• Expires (mm/dd/yy): 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 client will need to request a new IP address from
the router.
