Woo hooo...we have lift-off.
That was it...you have to stick to PPPoE and just select the pass-through. Which actually makes sense when you think about it. Communications on the Internet (and Ethernet et al for that matter) rely on a technique called a 'stack'. The stack has various levels in it, gradually getting more and more 'intelligent' the higher up in the stack you go.
PPPoE is not the lowest level but is there to set up the connection with login etc to the ISP. So you don't want the Vigor router handling this aspect. You want to 'pass it on' to another device to do the work ie the Asus router.
If opportunity doesn't knock, build a door.
