MAC Address authentication

Even though this answer is specifically for the DI-704, the steps and concepts are the same for all other D-Link gateways. If you have a modem with a USB connection only, it will not work with any broadband router due to the need of drivers to operate the modem. The key to this type of connection is recycling the power on the cable modem after physically connecting the modem to the D-Link gateway. Before you start: When first setting up the DI-704, only connect the computer that was used when you originally set up your broadband connection. Do not use hubs or switches for initial setup. Once the gateway is up and running, you can easily add additional computers, hub, and switches to set up a more complicated LAN. Summary: Physically set up the DI-704 by connecting your computer to a LAN port and your modem to its WAN port. From the Network Properties Control Panel, make sure your network card is set to "Obtain an IP Address Automatically". Restart your computer. From the Setup page of the DI-704´s web configuration, set the WAN type to Dynamic and check the box to Enable Renew IP Forever. Click Save. From the Tools page click the button to Clone MAC, then click Reboot to apply the changes. Power down both the modem and the DI-704. Power on the modem first, letting it stabilize, then power on the DI-704. Go Online! That´s the quick, down and dirty explanation. For more detailed setup information use the following step-by-step approach below. Step-by-Step Configuration: Step 1 Connect your broadband modem to the WAN port on the DI-704. Use the same cable that was used to connect your computer to the modem. The WAN light on the DI-704 should illuminate, verifying a good physical link. Step 2 Connect the same computer that was originally connected to the modem to an open LAN port on the DI-704. The corresponding port light will illuminate verifying that you have a good physical connection. Step 3 Release and Renew the IP address for your computer. The address you renew should be in the 192.168.0.100 to 192.168.0.199 range. Use the directions below to Release and Renew your IP address. For Windows 95, 98 and Me: Go to Start>Run and enter winipcfg. Click OK. In the IP Configuration control panel, select your network adapter from the drop-down menu. Click theRelease button, then the Renew button to obtain an IP address from the DI-704. The IP configuration information shows an IP address of 192.168.0.104 and Default Gateway address of 192.168.0.1, which is the default IP address of the DI-704. This information verifies the network adapter is properly configured and the computer is communicating with the DI-704 For Windows 2000 and XP: Go to Start>Run and enter cmd. Click OK. At the DOS prompt enter, ipconfig/release and then hit the Enter key to release your IP address. Then enter, ipconfig/renew and hit Enter to renew an address from the DI-704. The IP address, subnet mask, and default gateway information will be returned with this command. Notice in this example that the IP address is 192.168.0.104 and that the default gateway is 192.168.0.1. This information verifies the network adapter is properly configured and the computer is communicating with the DI-704. For Windows NT: Click Start>Run and enter command, then click OK. At the DOS prompt, enter ipconfig/release and hit the Enter key to release your IP address. Then enter ipconfig/renew and hit Enter to renew an IP address from the DI-704. Note: If you receive any error messages at this point, you may either have a problem with the functionality of your network card, or it may not be configured to obtain an address automatically in the TCP/IP properties. Step 4 Open your browser and type 192.168.0.1 in the Address window, then hit the Enter key. You do not need to type http://, only the IP address of the DI-704. This will connect you to the web configuration utility that lets you manage the DI-704. You are not on the Internet at this point. Type admin for the System Password, then click the Login button to login. Step 5 Select the Setup menu option from the bottom of the screen. Make sure the WAN type is set to Dynamic. Check box to enable Renew IP forever. If the WAN configuration is not set to Dynamic, click the Change button and select Dynamic. Next, click the Save button and then the Reboot button on the bottom of the screen. Click OK when prompted to Reboot right now? Step 6 Next, we need to do something called cloning the MAC address. This will insure that you can connect through your modem in the event that the MAC address, or physical address, of your network card has been registered with your ISP. Cloning the MAC copies the MAC address of your ethernet card to the WAN port of the DI-704. In other words, it will appear to your ISP will that it is your computer connected to the modem, not the gateway. That is why it is necessary to configure the DI-704 from the same computer tha
