IPv6 Over Tunnels
Let’s say you’ve taken my badgering to heart and decided to experiment with IPv6, but your ISP doesn’t offer IPv6. How can you play with IPv6 when all you get is an IPv4 feed?
Many companies offer a free IPv6 tunnel service, where they will route you through an IPv6 tunnel over IPv4. They will even give you an IPv6 /64 at no charge, so you can configure your home network for IPv6.
While I generally avoid recommending vendors in this book, I do recommend Hurricane Electric’s IPv6 tunnel service at http://www.tunnelbroker.net/. Its web interface is intuitive, and it even provides configurations for OpenBSD clients.
You should now have some understanding of managing IPv4 and IPv6 on OpenBSD. While your brain is recovering from all this stuff, we’ll turn to the topic of managing add-on software in OpenBSD.
