QT053 - Configuring a DG814 for ADSL Bridge Mode

Introduction

The DG814 is a connection-sharing gateway router with built-in ADSL modem, allowing the user to share an ADSL connection among several PC's, as well as providing basic NAT-firewall security.

For some requirements, it may be more appropriate to use a more sophisticated router, eg the FVS318 VPN router, in conjunction with a simple ADSL modem.  Netgear will soon be releasing the DM602 ADSL Modem for this purpose, but the DG814 can also be re-configured to operate as a modem.

Detail

In network terms, an ADSL modem functions as a transparent bridge, converting traffic between the ATM PVC used on the carrier side of the modem and (usually) ethernet frames used on the customer side.

To simplify typical configuration of the DG814, and avoid unnecessary confusion, the ability to re-configure as an ADSL modem is not part of the standard user interface.

To reconfigure the DG814 as a modem, connect to the router with a web browser using the URL http://192.168.0.1/DeviceType.htm.  (If you have changed the LAN IP settings of the DG814, adjust the URL as needed).

The following screen will be displayed:

 

 

Click the Device Type dropdown, and change the value from DG814 (GATEWAY) to DG814 (MODEM).  Click the Apply button.

 

 

The Basic Settings page will then be displayed:

 

 

Select the appropriate Multiplexing Method and VPI and VCI values and click Apply.  For most Australian ISP's, use the following values:

Multiplexing Method	LLC-Based
VPI	8
VCI	35

When the DG814 is re-configured as a modem, the internal DHCP server is automatically disabled to avoid a conflict with other network devices.  If you wish to reconfigure the DG814 at a later time, you will need to set your PC to use a static IP address.

Disclaimer

Re-configuration of the DG814 as a modem is not officially supported by Netgear at this time.  Any use of the information contained in this Quick Tip is entirely at your own risk.
