Always Broadcast
If all the computers on the LAN successfully obtain their IP addresses from the router's
DHCP server as expected, this option can remain disabled. However, if one of the
computers on the LAN fails to obtain an IP address from the router's DHCP server, it may
have an old DHCP client that incorrectly turns off the broadcast flag of DHCP packets.
Enabling this option will cause the router to always broadcast its responses to all clients,
thereby working around the problem, at the cost of increased broadcast traffic on the LAN.
Add/Edit DHCP Reservation
This option lets you reserve IP addresses, and assign the same IP address to the network
device with the specified MAC address any time it requests an IP address. This is almost the
same as when a device has a static IP address except that the device must still request an IP
address from the router. The router will provide the device the same IP address every time.
DHCP Reservations are helpful for server computers on the local network that are hosting
applications such as Web and FTP. Servers on your network should either use a static IP
address or use this option.
Computer Name
You can assign a name for each computer that is given a reserved IP address. This may
help you keep track of which computers are assigned this way. Example: Game Server.
IP Address:
The LAN address that you want to reserve.
MAC Address
To input the MAC address of your system, enter it in manually or connect to the router's
Web-Management interface from the system and click the Copy Your PC's MAC
Address button.
A MAC address is usually located on a sticker on the bottom of a network device. The
MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually
separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your
network device is a computer and the network card is already located inside the computer,
you can connect to the router from the computer and click the Copy Your PC's MAC
Address button to enter the MAC address.
As an alternative, you can locate a MAC address in a specific operating system by
following the steps below:
Windows 98
Windows Me
Windows 2000
Windows XP
Windows Vista
Mac OS X
Go to the Start menu, select Run, type in winipcfg, and hit Enter. A popup
window will be displayed. Select the appropriate adapter from the pull-down
menu and you will see the Adapter Address. This is the MAC address of the
device.
Go to your Start menu, select Programs, select Accessories, and select
Command Prompt. At the command prompt type ipconfig /all and hit Enter.
The physical address displayed for the adapter connecting to the router is the
MAC address.
Go to the Apple Menu, select System Preferences, select Network, and select
the Ethernet Adapter connecting to the router. Select the Ethernet button and
the Ethernet ID will be listed. This is the same as the MAC address.
