Apologies if I am covering old ground, but after a day of searching the internet I can't find a clear answer for what I want to do. However I know it is possible as I have read posts saying it is.
At the moment I have a Sky Router pushing everything into a DMZ which is picked up by wan2 on my 2820. This works in the main, but causes a few issues.
I have bought a secondhand HG612, and flashed it yesterday with the unlocked firmed. I contacted Draytek and obtained the MER beta firmware for my 2820.
At this point I flashed the 2820 and got it all working with the Sky Router. I then swapped out the Sky router for the HG612, and followed the instructions for entering my username & password (I tried using my old ADSL details as I already had them extracted xxxxxxxxx@skydsl - this worked fine when I was on Sky LLU).
The HG612 seemed to show a DSL light, but the 2820 never connected to/through it I then tried the firstname.lastname@example.org/install combination but that didn't seemed to work.
Is there something I need to configure in the HG612 to make it pass through to the 2820 so that the 2820 performs the authentication? I haven't as yet checked any logs, as I needed to get back online, so I just went back to the SkyRouter and re-enabled my old 2820 DMZ style configuration.
Draytek basically said:
Enabled WAN2, selected PPOE, enter username & password, disable, reboot.
Enable Dynamic/Static, reboot
