Configuring Dynamic Host Configuration
Protocol
You can configure your network and ATU-R130 to use the Dynamic Host Configuration
Protocol (DHCP). This chapter provides DHCP instructions for implementing it on your
network.
{ XE "DHCP:device modes" }The device can be configured as a DHCP server, DHCP
relay agent, or, in some cases, a DHCP client.
Note
Configuring DHCP Server
Note
First, you must configure your PCs to accept DHCP information assigned by a DHCP
server:
1.
Open the Windows Control Panel and display the computer's Networking
properties. Configure the TCP/IP properties to "Obtain an IP address
automatically" (the actual text may vary depending on your operating system).
{ XE "DHCP server:configuring the device as" }Next, you define the pools of IP
addresses you want to make available for distribution to your computers. These
addresses can be multiple public addresses that you have purchased from your ISP,
but are typically private addresses that you create. (LAN administrators often create
private IP addresses for use only on their networks.
2.
Log into Configuration Manager, click the LAN tab, and then click
the task bar.
The DHCP Server Configuration page displays, as shown in Figure 15.
Each pool you create displays in a row on the table on this page.
You can create up to eight pools; however, most users will need to create only one for their
LAN. Some users many want to create another that distributes an IP address to their USB
23
You can input settings for both DHCP server and DHCP relay
mode, and then activate either mode at any time. De-activated
settings are retained for your future use.
By default, the device is configured as a DHCP server, with a
predefined IP address pool of 192.168.1.2 through 192.168.1.13
(subnet mask 255.255.255.0). To change this range of
addresses, see " Viewing, modifying, and deleting address
pools" on page 25.
