ISP :

I recently purchased a TP-Link Archer D9 to replace a dieing-from-old-age Billion 7800N. My ISP is configured to allow me to have an IPv6 connection which worked flawlessly out of the box with my old modem, but I cannot get it to work with the Archer D9.

Everything is enabled from the ISP's end because it all used to work under a different modem, so I suspect I'm missing something in the config of my Archer D9, I just don't know what it is.

The status screen I see can be seen here - http://i.imgur.com/dXlk0Gv.png - any assistance in getting this working would be greatly appreciated. Below are the PPP logs from my modem.
