Optus SpeedStream 4200 Bridge Mode

Below you will find the step by step instructions required to succesfully set up the Optus SpeedStream 4200 Bridge Mode.

To enable an attached Router to function correctly with your Optus SpeedStream 4200 you need to switch it to “Modem Only” mode (referred to as Bridge Mode). Once that has been achieved, you will need to configure your Router to perform the PPPoE Login with your ISP.

Because of the large number of Routers available it is beyond the scope of this article to include the instructions for setting up the PPPoE connection on your Router. Refer to the Router Manual for instructions.

Stop! ImportantBefore you begin the setup process, you must perform a few basic preparation tasks. Read the Bridge Mode Setup Best Practices guide for more details. Consider the following tasks are mandatory:

  • Enable DHCP
  • Disconnect telephone line
  • Know the SpeedStream 4200 IP address
  • Power cycle the SpeedStream 4200 and PC.

How To Setup Optus SpeedStream 4200 Bridge Mode

Now that you have performed the preparation tasks, we can get started…

Step 1: Login to the SpeedStream 4200

Supported Browser IconsThe first step is to load the SpeedStream 4200 Router Management Interface page using your Internet Browser. I prefer to use Internet Explorer because it always works, but if you have Firefox, it should work ok. If you find that your changes are not being saved or buttons don’t work, then stick with Internet Explorer.

The default IP address of the SpeedStream 4200, with Optus firmware, is Enter the following into the address bar of your browser : (Or click the link to open in a new window).

If the link above does not work your network configuration may not be using the default settings. You will need to change “″ to the IP address of your network Default Gateway to continue.

If you are unsure how to find the IP address of your Router, you can watch our Video which shows you exactly what to do (todo: Add link to video).

The SpeedStream 4200 Router Management Interface Page should now be displayed. Click on the Setup menu option on the left to display the setup sub options.

Step 2: Set Up Dynamic DNS

Disable any Dynamic DNS settings you may have had. This needs to be set up on the replacement Router if you’re using Dynamic DNS.

Step 3: DHCP Configuration

Disable the DHCP Server Option: Make sure you don’t reboot if prompted after clicking the Save Setting button! If you are using DHCP on your internal Network this should also be configured on your Router.

Tip!Tip! – You can actually leave DHCP enabled! With DHCP enabled, you will be able to easily connect to check ADSL status or run diagnostics as needed.

Step 4: Mode Selection

Set the correct operation mode. This is the main difference between the Optus firmware and other firmware versions. Don’t be fooled into thinking the Optus or Full Bridge option is correct. It must be NAPT, as shown below because the other options don’t work!

Step 5: WAN Configuration #1

This is where we actually configure Bridge Mode. If you had been running in Optus Bridge mode, there may not be any entries in the table. If there are multiple entries, delete all except one. The Type and/or Name is not important.

If there is an existing entry, click on “8/35″ (or equivalent) entry under the VC column heading!

If you don’t have an entry, click the “Add a New VC” button.

Now we just follow the “Wizard” and set the entries as appropriate.

Step 6: ATM Settings

Make sure you have the VPI and VCI set correctly for your location. In Australia, it should be set to VPI: 8 and VCI:35 as shown below. Also ensure you select the LLC Encapsulation Type. VCMUX is applicable for a PPPoA connection and we will be using PPPoE.

Select Bridge only and click the Next >> Button.

Step 9: Interface Options

On this configuration page we are basically turning off all the Router features, that should not work anyway, as the gateway will be running in Modem Only Mode. This is the most important setup page to get right. Notice, I turn OFF Everything!!!

Once the options have been set click the Next >> Button.

Step 10: Connection Name

It really does not matter what you put in here as it does not appear to be saved anyway. Just to be correct, I use the following Connection Name: PPPoE 8/35.
