As you point with a Native IPv6 network there are some nice QOS features but
these benefits are lost with the IPv4 tunneling.
Then we need to make the most out of what IPv4 and packet shaping can give
use. The different services, as in web, email and voip on the FreedomBox
will need to be packet shaped to suit there needs. So that the up link on
the FreedomBox is has share as possible.
