You do not need to set up connection for either IPv6 Connection (IPoE) or IPv4 over IPv6 Connection (DL-Lite). 
However, if the IPv6 feature of your computer or router is disabled, you need to enable it. Please check the status before the use. 
See the following page for more details. 
Setup Guide: IPv6 Connection Feature

If auto setup has failed to deliver the settings information of IPv4 over IPv6 Connection (DS-Lite), you will be informed by an email. 
Please check the details of the email and take the necessary steps.
