Broken from this step onwards. You now have two default routes and two
IPv6 addresses with access attempts from external users to both. Many
of your devices are not smart enough to match the route to the source
address. Others are capable (e.g. Linux) but only if you're savvy
enough to do some custom configuration beyond an entry in the /etc
configuration file.
