So I did some back to factory firmware updates as I thought it might be a good chance the wipe out some old mac filtering and start afresh... apparently my networking skills have disappeared as now I can't for the life of me get the Asus to pick up the Draytek... 

Does anyone have this configuration that they can point me in the right direction?

I have the Draytek set up as per the Snappernet Chrous VDSL bridge guide, but the Asus won't connect to it no matter what I do. 

Am I doing/missing something dumb? I can't post screens of the setup pages as i'm well past the point of caring for the night. Will see how I go in the morning.
