I have installed a new router at my house running the open source WW-DRT software. I want to enable IPv6 but I am not sure what settings I need. The WW-DRT tutorial on IPv6 lists many different types of IPv6 setups, I tried a couple of them but none worked to access IPv6 address outside my LAN.

I am using Vodafone's latest Cisco cable modem (if that makes a difference).

Any help would be appreciated.
