9 DHCP Configuration
You can configure your network and RTA100+ ADSL
Modem/Router to use the Dynamic Host Configuration Protocol
(DHCP). This chapter provides instructions for implementing
DHCP on your network.

The device can be configured as a DHCP server, DHCP relay
agent, or, in some cases, a DHCP client.
 DHCP server - It will maintain the pool of addresses and
distribute them to your LAN computers. If the pool of
addresses includes private IP addresses, you must also
configure the Network Address Translation service, so
that the private addresses can be translated to your
public IP address on the Internet. Both DHCP server and
NAT are enabled in the default configuration.
 DHCP relay agent
- If your ISP performs the DCHP
server function for your network, then you can configure
the device as a DHCP relay agent. When the RTA100+
ADSL Modem/Router receives a request for Internet
access from a computer on your network, it contacts
your ISP for the necessary IP information, and then
relays the assigned information back to the computer.
 DCHP Client
- If you have another PC or device on your
network that is already performing the DHCP server
function, then you can configure the LAN port on the
RTA100+ ADSL Modem/Router to be a DHCP client of
that server.

Each pool you create displays in a row on the table on this
page. You can create up to eight pools. In this example, one
pool has been created for the LAN interface and another for
the USB interface. Additional pools may be needed when the
device is configured with multiple LAN interfaces.
