4.3 DHCP Configuration

includes the IP address, MAC address, host name and lease time are displayed in the list.

Figure 4-8. Configure DHCP server settings for the LAN

The three options for DHCP service are as follows:

You may use the ADSL2+ Router as a DHCP server for your LAN.

You can disable DHCP service and manually configure IP settings for all workstations.

You will use a DHCP service provided by your ISP, in which case DHCP should be disabled on the

ADSL2+ Router.

4.3.1 DHCP Server Settings for the LAN

The default setting of ADSL2+ Router 's DHCP server is disabled. While you click to select the Enabled

radio button under the DHCP Server option, the device will become the default gateway for DHCP clients

that connected to it. When the ADSL2+ Router is used for DHCP it becomes the default gateway for DHCP

client connected to it. Keep in mind that if you change the IP address of the ADSL2+ Router, you must

change the range of IP addresses in the pool used for DHCP on the LAN.

4.3.2 Use the ADSL2+ Router for DHCP

To use the built-in DHCP server, click to select the DHCP Server option if it is not already selected. The

IP Address Pool settings can be adjusted so that up to 253IP addresses are available for use. The Starting

IP Address is the lowest available IP address (default = 192.168.1.2). If you change the IP address of the

ADSL2+ Router this will change automatically to be 1 more that the IP address of the ADSL2+ Router. The

Ending IP Address is the highest IP address number in the pool (default = 192.168.1.33). Select the Lease

Time from the pull-down menu. This is the amount of time that a workstation is allowed to reserve an IP

address in the pool if the workstation is disconnected from the network or powered off. Lease time options

vary from 1 hour to 1 week. DHCP client workstations on your LAN must be properly configured to use

DHCP service. Be sure to save the new settings.
