Dual-Band Wireless A/G Broadband Router
Multicast Pass-Through
IP Multicasting occurs when a single data transmis-
sion is sent to multiple recipients at the same time. Using the Multicast Pass-
Through feature, the Router allows IP multicast packets to be forwarded to the
appropriate computers. Keep the default setting,
Enable

or select

MAC Cloning
You can clone the MAC address of your PC’s network adapter
onto the Router.
A MAC address is a 12-digit code assigned to a unique piece of hardware for
identification. Some ISPs require that you register the MAC address of your
PC’s network adapter, which was connected to your cable or DSL modem dur-
ing installation. To avoid calling your ISP and changing the MAC address that
is registered with the ISP, follow these instructions:
1. Select
Enable
.
2. Enter your adapter’s MAC address in the
MAC Address
field.
3. To save your new settings, click the
Apply
button. To cancel your changes,
click the
Cancel
button. To get more information about the features, click
the
Help
button.
To disable MAC address cloning, keep the default setting,
Disable
.
If you do not know your adapter’s MAC address, follow these instructions:
1. Click
the
Start
button, and select
Run
.
2. Enter
command
in the field provided, and press the
OK
button.
3. At the command prompt, enter
ipconfig /all
. Then press the
Enter
key.
4. Write down your adapter’s physical address; this is the adapter’s MAC
address.
Remote Management
This feature allows you to manage your Router from a
remote location, via the Internet. To disable this feature, keep the default set-
ting,
Disable
. To enable this feature, select
Enable
, and use the specified port
(default is
8080
) on your PC to remotely manage the Router. You must also
