DHCP Configuration
You can configure your network and HM210dp/di to use the Dynamic Host
Configuration Protocol (DHCP). This chapter provides instructions for implementing
DHCP on your network.
7.1
HM210dp/di DHCP Modes
The HM210dp/di 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 (NAT) 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 DHCP server function for your
network, then you can configure the device as a DHCP relay agent. When the
HM210dp/di 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.
•
DHCP client - If you have another PC or device on your network that is already
performing the DHCP server function, you can configure the LAN port on the
HM210dp/di to be a DHCP client of that server.

Select LAN > DHCP Server. The DHCP Server Configuration page appears:
Figure 27: DHCP Server Configuration page
Each pool you create displays in a row on the table on this page. You can create
up to eight pools. Additional pools may be needed when the device is configured
with multiple LAN interfaces.
