Evening folks has anyone got this working on a draytek 3910. I had it working briefly on the 2960 but turned it off as I kept getting ipv6 conflicts . However the settings on the 3910 are totally different and don't match any of the earlier models using a version of the same os.

Oops forgot to mention BT is via a draytek 130 and that's picking up the ipv6 address fine.

The other wan is virgin and they don't supply ipv6.

What have you configured in the IPv6 setup? (page 11-2-2-3 onwards in the 3910 manual)
Have you tried DHCPv6 Client?

I am not familiar with the 130 but if it is a modem how does it get an ipv6 address - surely it just passes ip packets through?

Yes tried dhcp6 client and no go. You can plug the draytek 130 directly into a pc and set up ppoe connection. Open the web page and look at the stats.

LOL got it working the setting was ppp. I tried that before but it didn't work I'm sure of it.
