How to config IPV6 for ASUS router

Hi,

I've looked through here and did a Google search but can't find exactly what I am looking for.  Tried calling Cox to ask them what kind of IPV6 connection I should pick and they wouldn't help me of course.

The RT88U router I have has 5 different connection types.  I chose Native and it seems to work.  Went to http://ipv6-test.com/ and scores a 13/20 and states that IPV6 is supported.  I assume everything is working now just wanted to make sure.  Thanks.
