This FAQ has 3 Major sections:
Section 1 - Overview
Section 2 - Motorola/Netopia 2210 modem configuration
Section 3 - D-Link router configuration information
Section 4 - Connections and power up
Important Note: Due to some known operational issues it is VERY important that you have the latest firmware on your D-Link router. Please go to the D-Link Support Site for firmware updates.
The best configuration for networking a router with a 2210 is to set the 2210 to "Bridged Ethernet" mode and allow the DLink router to do the routing and DHCP functions. The 2210 is also a router with full DHCP functions and may not function correctly when connected directly to another router. Not changing the modem to Bridged Ethernet will result in double NAT'ing, increased latency, possible IP conflicts, or possibly a network that doesn't work at all.
Before proceeding both the modem and router should be set to default. Despite what the help desk tech tells you, resetting the modem does not put it into Bridged Mode.
The BellSouth Installation CD and Connection Manager are not required to use this configuration.
Since BellSouth assigns static WAN IPs via your username the configurations shown are applicable to both dynamic and single static IP customers. Select dynamic PPPoE regardless of your setup.
You must connect the 2210 directly to the computer's NIC to make the necessary changes before you connect the router, because you will be unable to access the modem interface after you connect the router. The reason is that the modem interface is 192.168.1.254 which is a local IP. By default, most routers do not have the capability to route a local IP out of their WAN port (where your 2210 is connected). Additionally, they may be on completely different subnets. After you have made the changes to the 2210 you can then connect the router and configure it for use with FastAccess. There are several alternatives around this problem. One method involves extra equipment (second NIC and a hub) and major configuration changes. The second method requires you to utilize the router as a simple switch and use the 2210's PPPoE and DHCP functions. Click here for more information.
If you encounter any problems simply reset the 2210, connect it directly to your NIC, restart your computer, log into the interface, and start over again.
Verify that your NIC card is set to "Obtain IP Address Automatically". Completely power down the 2210 and the computer(s). Power up the modem and press the reset button on the back of the modem. After the modem has fully initialized connect the 2210 to the NIC and then power up the computer.
Open a browser session and enter "192.168.1.254" in the address field to access the 2210 interface.
Enter your BellSouth Username followed by "@bellsouth.net" in the User ID field. Enter your BellSouth Password in the Password field. Re-enter your BellSouth Password in the Confirm Password field. Click on Next. Update the Auto Calender Update Configuration as desired and click Next. The modem will try to initiate a session and then return to the main menu.
Click on Broadband DSL Line from the top menu. Click on Configure Connection from the right menu. Select "Bridged Ethernet" from the Protocol pull down. Click on Save and restart the connection at the bottom. This will automatically restart the modem and the interface will return after the changes are saved. Note: functions like NAT, DHCP, IP Passthrough, and username and password will be disabled or irrelevant and can not be selected. After the modem has restarted, power down both the computer and the modem then physically disconnect the 2210.
After the PC is powered down connect one of the router LAN ports to the computer NIC and power up the router and then the computer.
Use the following steps to configure your D-Link DI-604 Router. Important Note: You must use the email@example.com format for your username. If you do not add "@bellsouth.net" after your username you will be unable to connect to the internet.
Power everything down and physically connect the 2210, the router, and any computer(s).
Power up the network equipment in this order:
•2210 Modem (wait till the Ready light is a steady green)
Open a browser session and go surfing!
Important Additional Information
•The 2210 has an "Internet" light that is green whenever there is an active PPPoE session initiated by the 2210. Since you are using the DLink to establish the PPPoE session the light will stay off. This is normal.
•You should check your tweak settings to optimize your new network. Reminder: If you are required to change your MTU, make sure that it is identical on all equipment (PCs and routers) in the network. For more information about changing MTU on a D-Link please click here.
Doesn't work right on the D-link DGL-4300. Must be an old firmware version of the Motorola 2100 modem, because my PPP options are in a totally different menu.
