Using the Multicast PassThrough feature, the Router allows IP multicast packets to be forwarded to the appropriate computers. Keep the default setting, Enable, to support the feature, or select Disable to disable it. 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 during 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 setting, 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 change the Router's default password to one of your own, if you haven't already. A unique password will increase security. 39
