As some of you may know, I’ve been playing around with IPv6 quite a bit lately. One specific IPv6 technology which has gotten me quite excited is the Teredo automatic tunneling protocol. Teredo allows you to obtain a globally routable IPv6 address when you only have access to the IPv4 internet, even if you are behind a NAT router1!
IMPORTANT: This package is a prerelease version intended for early adopters, and is NOT intended for widespread deployment. If you decide to install and use this experimental package, you should subscribe to the miredo mailing list, paying serious attention to any security advisories.
