Billion Modem / Router ==> Router
-- Conversion Guide [WAN port from ADSL to Ethernet] ....

Important notes:
  * this guide is limited to particular Billion (or equivvalent) ADSL modem / router units;
  * also note that you can continue to use the wireless LAN and/or VoIP capabilities of the unit.
  * further more if you have a VGO model, then you can also continue to have VPN endpoint capability too!


This a guide for converting a Billion/Open ADSL gateway to a fully functional router for non ADSL Internet connections whilst also retaining all the functions of the original unit.

This is a simple procedure that involves converting one of the LAN Ethernet ports to be a fully functional WAN Ethernet port in place of the ADSL port.  This is useful if you already have the device and you change your Internet connection to one that no longer uses ADSL, but instead has standard Ethernet connectivity.
Usually you would need to buy a new device to achieve the desired functionality, but perhaps that isn't necessary due to this guide.

This is a guide that may not be suitable for all owners of such equipment as it requires a little technical skill.  Please be aware that we take no responsibility for any failure to perform this operation on any device whatsoever.  Therefore for those that are not technically inclined enough to understand and follow this guide, it might be a better option to simply buy a new device and pass on the old one for soembody else to use.  Having said that, there are methods and tools to return the device back to it's original factory configuartion if necessary.

Billion 7402/7404 series (with or without VoIP, wireless or VPN capabilities)
- this may also be applicable to the older 741 modem as well...
   The "Open 824RLW" model is actually a re-badged 7402VGP device.

The procedure requires you to re-configure your device to function in a way that was not intended by the manufacturer, however, the device is certainly capable just the same. We are simply re-assinging which port is used for the WAN connection via adjustments to particular settings. Note that are not available in the usual web interface; you will need to access the device via the CLI (or command line interface).  Choose a 'TELNET' tool that suits this requirement.

Telnet product options:

  1. The "telnet" application is usually found in standard installations of Windows, Linux, Unix, etc...
  2. PuTTY terminal access program (you cannot use ssh though)
   PuTTY is definitely my preferred tool, it is an excellent free tool

NB: If you are using Windows Vista and prefer to use it's 'inbuilt' telnet program, then see the guide here:
- you are most likely better off using PuTTY anyway...


Make a Telnet connection to the device:

telnet    (I setup a putty profile myself)
[this is the default IP]
-- make sure you use telnet option if using PuTTY (not ssh here) ...

Enter the login details that you would normally use when accessing the web interface.

Once you have logged in, simply copy and paste the text (command) lines into the telnet session as required.

Windows Vista notes (from the above reference):

  1. Click on Start button, then go to Control Panel -> Programs.
  2. Under the Programs and Features section, click Turn Windows features on or off.  If User Account Control permission confirmation request warning pops up, click on Continue.  If you are prompted for an administrator password, type the password.
  3. In the Windows Features dialog box, select (tick) the Telnet Client check box.
  4. Click OK.  Wait for the installation to finish.
  5. Once installed, you can find Telnet Client by typing Telnet in Start Search.


In the CLI (before any changes)
  port ethernet show

  Note the shown values in the output for these particular variables
  [for example, these are from my 7404VGOM]

p1vlanmember=0x31    p2vlanmember=0x31    p3vlanmember=0x31    p4vlanmember=0x31

In the Web GUI interface [default IP]
Configuration -> LAN -> Bridge Interface
  You can also get to this more quickly with this link:

  Choose a port to use as WAN - such as P3
    - p4 is used for console and LAN, so it is better not to choose that one

  Click on 'ethernet P3' to uncheck it;
  Click on 'ethernet1 P3' to re-assign it here;
  Click on the 'Apply' button.

Now back in the CLI note the new values for the vlanmembers
  port ethernet show

*You will see that any change to the VLAN settings via the gui will change the values of the vlanmembers, one should be different from the others.*

With my 7404VGOM each was initially set at 0x31, after having changed p3 from 'ethernet' to 'ethernet1' as above, I then had p1, p2 and p4 with a value of 0x11 whilst p3 had a value of 0x4.

p1vlanmember=0x11    p2vlanmember=0x11    p3vlanmember=0x4      p4vlanmember=0x11

The all important DIFFERENT VLANMEMBER is what you will need to know for further works here

Here are some other vlanmembers and their values or different models
NB: these may change without notice for any model!

  You just have to find the right ones for your particular unit.

Here are some vlanmember values that have been found to be in use

This table shows the values AFTER a change has been made in the web GUI

ModelMembers / Values
p1vlanmember=0x11    p2vlanmember=0x11    p3vlanmember=0x4  
p1vlanmember=0x1F    p2vlanmember=0x1F    p3vlanmember=0x4  
p1vlanmember=0x7      p2vlanmember=0x7      p3vlanmember=0x8      p4vlanmember=0x7  
p1vlanmember=0x11    p2vlanmember=0x11    p3vlanmember=0x4      p4vlanmember=0x11

NB: these values may or may not be correct for your unit
- this may simply be due to a firmware change...


Now the CLI scripts you need to use.

Copy and paste the required CLI commands to suit your requirements with suitable adjustments.
* be sure to copy as plain text *

Now there are three common methods of Internet connectivity used by ISPs:

  1. PPPoE  This is most common one, most of you would recognise it as the one with a user name and password.  Common with ADSL connections and routed connections.
  2. DHCP  Common on cable connections where no password is required.
  3. Fixed IP  Some setups require a fixed IP address (although this is much less common these days).

Okay, here are the CLI commands to choose from....

   These 3 [or 4 as the case may be] won't be required if you set the VLAN in the web GUI:
   port ethernet set p1vlanmember 0x11
   port ethernet set p2vlanmember 0x11
   port ethernet set p3vlanmember 0x4
   port ethernet set p3vlanmember 0x11

   port ethernet set vlan enabled
   port ethernet set switchreset true
   transports delete wanlink

   These ones for PPPoE (dialout) connection type:
   pppoe add transport wanlink dialout eth 1 ethernet1
   pppoe set transport wanlink username username@&at;
   pppoe set transport wanlink password <password>
   ip attach ipwan wanlink

   These ones for getting IP via DHCP for WAN connection:
   ethernet add transport ethernet1 ethernet1
   ip attach ipwan ethernet1
????? The following also for DHCP WAN setup ????
   dnsclient add server DDD.DDD.DDD.DDD
   dnsrelay add server DDD.DDD.DDD.DDD
????? The above also for DHCP WAN setup ????
   ip set interface ipwan dhcp enabled
   dhcpclient update

   These ones for using fixed IP for WAN connection:
   ip set interface ipwan ipaddress XXX.XXX.XXX.YYY 255.255.255.MMM
   ip add route default gateway XXX.XXX.XXX.ZZZ
   ip attach ipwan ethernet1

????? The following also for Fixed IP WAN setup ????
   dnsclient add server DDD.DDD.DDD.DDD
   dnsrelay add server DDD.DDD.DDD.DDD
????? The above also for Fixed IP WAN setup ????

   The following is required to save the configuration changes to flash memory.
   system config save
   system restart

NB: Make sure that you adjust the vlanmember id, username and password of your ISP as required.




Well you do the commands, cut and paste it into telnet window, and let it run.  What happens next.  Once you have completed all of the commands, plug a LAN cable from the last port on the router into your wall socket/cable modem/whatever it is that you are using.

Don't worry about the ADSL light .  it will keep flashing forever until it detects line sync (which it will never do if you don't have an active ADSL service on your phone line!).  In some models the configeration allows you to turn off that feature, and thus the flashing light.

Log in to the web config page (for Billion/Open by visiting

You should notice on the main page that it shows the router as having no ADSL sync however it should show your current WAN IP address .  you should now be connected to the Internet.



The great thing about Billion/Open products is they are almost unbreakable, appart from hitting it with a hammer.  If for whatever reason you make a mistake, the first thing to do is just hit factory reset, via your manual, and that usually is fine, as all we are doing is minor software changes.  If by some unthinkable event you manage to "brick" the unit, the recovery software from their sites is extremely good, and unbricks them so easily.  Then you can try again.

To make life trouble free, before you start

  1. check manual on how to factory reset your device.  This is just in case.
  2. As an extra safety measure, download the recovery unit for the unit from the homepage.  That way your not stuck if things go horrible wrong.
  3. Write down all your settings before you start, so you dont forget them.
  4. keep records what you do and change, in case you need to backtrack.
  5. if in doubt, have on call a technical friend for your own reassurance.

Thats it, enjoy more out of your Unit.
