OpenWRT 14.07, IDNet ADSL and PPPoE anyone have a working config?

[adrinux]

Just updated my tp-link1043nd to openwrt barrier breaker final, but have had issues with the ¨automatic¨ ipv6 support. Specifically that when I enable the wan6 interface both wan6 and wan interfaces die - connection dies in other words.

Currently the tp-link connects via PPPoE at a Draytek Vigor 120 adsl modem.

So does anyone have a working ipv6 setup with barrier breaker connecting over pppoe? It would be nice to have some idea which protocol to set my wan6 interface too. The obvious seemed to be ipv6 dhcp client, but as I said that doesnt work.

Have already posted in the openwrt forums but any idnet specific suggestions would be welcome.
