Use The Router For Dhcp; Disable The Dhcp Server - D-Link DSL-522T User Manual

To display the DHCP Settings window, click the DHCP button in the Home directory. Any active DHCP
Clients appear at the bottom of the window in the DHCP Clients List. The IP address and MAC address for
active DHCP clients are displayed in the list.
The two options for DHCP service are as follows:
You may use the Router as a DHCP server for your LAN.
You can disable DHCP service and manually configure IP settings for workstations.
You may also configure DNS settings for the LAN when using the Router in DHCP mode. In Auto DNS
Mode, the Router will automatically relay DNS settings to properly configured DHCP clients. To manually
enter DNS IP addresses, select the Manual DNS Mode option and type in a Primary and Secondary DNS
IP Address in the field provided. The manually configured DNS settings will be supplied to clients that are
configured to request them from the Router.
Follow the instructions below according to which of the above DHCP options you want to use. When you
have configured the DHCP Settings as you want them, click the Apply button to commit the new settings.

Use the 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. The Starting IP Address is the lowest available IP address (default
= 192.168.1.2). If you change the IP address of the Router this will change automatically to be 1 more that
the IP address of the Router.
The Ending IP Address is the highest IP address number in the pool. Type in the Lease Time in the entry
field provided. This is the amount of time in seconds that a workstation is allowed to reserve an IP address in
the pool if the workstation is disconnected from the network or powered off.

Disable the DHCP Server

To disable DHCP, click to select the No DHCP option and click on the Apply button. Choosing this option
requires that workstations on the local network must be configured manually or use another DHCP server to
obtain IP settings.
If you configure IP settings manually, make sure to use IP addresses in the subnet of the Router. You will
need to use the Router's IP address as the Default Gateway for the workstation in order to provide Internet
access.
