Use The Router For Dhcp - D-Link DSL-G624T User Manual

To change the LAN IP Address or Subnet Mask, type in the desired values and click the Add/Apply
button. Your web browser should automatically be redirected to the new IP address. You will asked to login
again to the Router's web manager.
The DHCP server is enabled by default for the Router's Ethernet LAN interface. DHCP service will supply
IP settings to workstations configured to automatically obtain IP settings that are connected to the Router
though the Ethernet port. When the 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 Router the range of IP addresses
in the pool used for DHCP on the LAN will also be changed. The IP address pool can be up to 253 IP
addresses.
There are two options for DHCP service:
•
You can 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 (Advanced >
DNS Setup). When "Obtain DNS server address automatically" is clicked under DNS Server Configuration
on the DNS Setup menu, the Router will automatically relay DNS settings to properly configured DHCP
clients. To manually enter DNS IP addresses, click the "Use the following DNS server addresses" radio
button and type in a Preferred DNS Server and Alternate DNS Server in the fields 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 Add/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.
Static IP on LAN
If the Router has the DHCP server enabled it is possible to permanently assign IP addresses to workstations
specified by their MAC address. Up to five IP addresses may be assigned to five different devices. This will
take the chosen IP address used out of the available addresses in the dynamic IP address pool and give a
permanent lease time for the IP address to the selected device.
To assign an IP address that will not age out, type in the MAC Address of the device and its static IP
Address in the spaces provided under Add DHCP Reservation. Use the format: 00-00-00-00-00-00 for the
MAC address and the standard format: 192.168.0.xxx for the IP address. A Static DHCP Client List will
appear below the DHCP Client list with any clients that have been configured for static IP address
assignment.
