DHCP Server Settings
The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The
Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to
each computer on your network. If you choose to enable the Router’s DHCP server option, you must make sure
there is no other DHCP server on your network.
DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you
don’t want a DHCP server, then select Disabled (no other DHCP features will be available).
Assign Static DHCP. Every time a PC reboots, it is assigned a new local IP address by the Router. If you want a PC
to be assigned the same IP address every time it reboots, then click the Assign Static IP button.
On the Static DHCP Client List screen, enter a client name, then enter the static local IP address in the Assign this
IP field, and enter the MAC address of the PC in the To this MAC field. Then click the Enabled checkbox. When you
have finished your entries, click the Save Settings button to save your changes. Click the Cancel Changes
button to cancel your changes. To exit this screen, click the Close button.
If you want to see a list of DHCP clients, click the DHCP Client Table button. On the DHCP Client Table screen, you
will see a list of DHCP clients with the following information: Client Names, Interfaces, IP Addresses, and MAC
Addresses. From the To Sort by drop-down menu, you can sort the table by Client Name, Interface, IP Address, or
MAC Address. To view the most up-to-date information, click the Refresh button. To exit this screen, click the
Close button.
Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller
than 192.168.1.254. The default Starting IP Address is 192.168.1.100.
Maximum Number of Users. Enter the maximum number of PCs that you want the DHCP server to assign IP
addresses to. This number cannot be greater than 253. The default is 50.
IP Address Range. The range of DHCP addresses is displayed here.
Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the
Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”
this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address.
The default is 0 minutes, which means one day.
WINS. The Windows Internet Naming Service (WINS) manages each PC’s interaction with the Internet. If you use
a WINS server, enter that server’s IP Address here. Otherwise, leave this blank.
