I've read the V120 manual time and again, Google searched and read all the forum postings etc but can't for the life of me get the V120 working in fully bridged mode ..... or at least I assume I can't as I can still access the setup web page when the V120 is behind a Netgear WNDR 4500 router ... which I don't think I should be able to if fully bridged.

My ISP is Telecom NZ and my settings are:

PPPoE/PPPoA Client Enabled
VPI 0
VCI 100
Encapsulation VC MUX
Protocol PPPoA
Modulation Multimode
User name ********
Password ********
PPP Authentication PAP or CHAP
PPPoE Pass Through Box checked

I then power cycle the whole system in order: modem / router / iMac ......

... but all I get is that there's no internet connection.

Perhaps I shouldn't worry as I seem to otherwise get a good connection, good speeds etc but having read so much about the fabled V120 fully bridged mode for which presumably there's some technical benefit (exactly what is the benefit?) it would be good to get it properly configured.

Is anyone able to help on this?

It doesn't use the username and password in the modem when it's in fully bridged mode.
Once you have the passthrough box ticked you need something else that will do PPoE.

e.g. If you have the draytek plugged into an airport extreme, you put in your username and password settings in the airport extreme.

All you do is tick the box that says PPPoE passthru, all the other settings you've put in aren't needed.

Your best bet would be to reset the device and start from scratch reading the manual or the Draytek support page http://www.draytek.net.nz/draytek/support/

What I suggest you to do is to check to make sure you have PPPOE dial as the WAN setup instead of DCHP/Static.

Use the any normal Telecom ADSL login, example: user@xtrabb.co.nz.

Check the logs if it fails.

If that doesn't work, connect the Vigor 120 modem directly to a testing machine and create a broadband(PPPOE) connection. This should help you isolate the problem. Hint: You may want to turn your firewall on.

There are a lot of discussions here about the benefits, it's mainly for advanced users who wants to choose their preferred PC/hardware router for routing and firewall.

I got mine working on the first try with WNDR3700 a month back.

When the Vigor 120 is in "PPPoE pass through" mode, its status will always show it is disconnected. You will get ADSL status information like sync speed, SNR margin and loop attenuation etc, But it will always show the WAN connection as disconnected. This is because it is acting as a dumb bridge. The next device connected to the Vigor 120 (your router, pc etc) is one responsible for doing the authentication, and "connection" to the internet.
So for this setup to work, what ever the device is, that is connected to the Vigor 120 has to connect to the Vigor using PPPoE.

Many thanks for your help guys. I've got a better understanding of why I haven't been able to get it working yet and what I need to do to get it working.

Msnforum .... can I ask where in the Netgear Genie you (i)set the WNDR3700 to connect to the V120 with PPPoE?, and (ii) entered your username and password provided by your ISP? I having difficulty finding these settings in the Netgear Genie for the WNDR4500 ..... which presumably must be the same or similar to that for the 3700?

hiya,

What is mentioned so far should get you online but be careful to only include account & password fields on the dialer [Netgear].

Don't give the service a name if it is an option & Don't add any custom fields because the Draytek does not know how to interpret these.

If a service name is included, for example "Telecom" the modem will not authenticate correctly these need to left blank.

Hope this helps,
jw

It will be here:
