LAN DHCP Server Settings

DHCP Server Settings

Dynamic Host Configuration Protocol (DHCP) allows the gateway to automatically

obtain the IP address from a DHCP server on the service provider’s network. The

service provider assigns a global IP address from a pool of addresses available to the

service provider. Typically the IP address assigned has a long lease time, so it will likely

be the same address each time the Router requests an IP address. If DHCP is not

enabled on the Router, it is necessary for the user to assign a static IP address to each

computer on your LAN.

To set up DHCP for your LAN, first enable the Router as a DHCP server by clicking the

Enable DHCP Server radio button in the window above. The next step is to set a range

of IP addresses that you wish to allot to the devices on your LAN by entering a starting

and ending number of addresses within the LAN subnet in the DHCP IP Address

Range. This may be in a range from 2 to 254 (192.168.0.2 – 192.168.0.254).

Computers on your LAN will have an IP address within this range then automatically

assigned to them. Finally, choose the DHCP Lease Time, which is the time the Server

will set for devices using DHCP to re-request an IP Address. Clients authorized for

DHCP will be listed in the Dynamic DHCP Client List near the bottom of the window.

Click Save Settings to implement information set in this table. The DHCP Server is

enabled by default. DHCP may also be statically configured as well. This method allows

the router to assign the same IP address information to a specific computer on the

network, defined by its MAC address. This computer will get the same DHCP

implemented IP address information every time the computer is turned on and this IP

address will be specific to that computer’s IP address on the local network. No other

computer can be assigned this address. This is useful for computers on the LAN that

are hosting applications such as HTTP or FTP. First, the user must enter the Host

Name and the IP Address for that computer in the spaces provided. Next, the user

must enter the MAC Address of the computer in the space provided. Click Save

Settings to implement these static settings.
