Configure debian server host for ipv6
<p>I nee my website to be accessible though ipv6 network, I used <a href="https://wiki.debian.org/DebianIPv6" rel="nofollow">this page</a> (IPv6 6to4 Configuration) and got some results but my website is still not reachable in ipv6.</p>

<p>I tested my domain (creforma.fr) on several websites:</p>

<p><a href="http://ipv6-test.com" rel="nofollow">http://ipv6-test.com</a></p>

<blockquote>
  <p>AAAA DNS record       fe80::207:cbff:fe03:aee9
  IPv6 web server         web server is unreachable : Invalid argument</p>
