<h1 id="enabling-teredo-on-windows-vista-and-above">Enabling teredo on Windows Vista and above</h1>
<p>Linux users: install miredo and start it and you have IPv6. Optionally set server in /etc/miredo/miredo.conf .</p>
<h2 id="the-easy-way">The easy way</h2>
<p>Create file called whatever.reg with this content:</p>
<pre><code>[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
"AddrConfigControl"=dword:00000000
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\TCPIP\v6Transition]
"Teredo_DefaultQualified"="Enabled"
"Teredo_State"="Enterprise Client"
"Teredo_ServerName"="teredo.ipv6.microsoft.com"</code></pre>
<p>Now double click it and answer Yes to UAC and warning about importing registry values. Now you can either reboot or update Group policy by opening cmd.exe and running</p>
<pre><code>gpupdate /force
netsh interface teredo show state</code></pre>
<p>teredo.ipv6.microsoft.com can be replaced with any other teredo server in the .reg file.</p>
<h2 id="the-hard-way">The hard way</h2>
<pre><code>netsh int ipv6 set teredo client teredo.trex.fi</code></pre>
<p>Optional, sets Teredo server. The default one is provided by Microsoft, this isn't, but this is in Finland where I live.</p>
<pre><code>route print</code></pre>
<p>Scroll up and see what is number of teredo. It's near top.</p>
<pre><code>netsh
interface ipv6
show teredo
add route ::/0 interface=XX</code></pre>
<p>Replace XX with number from "route print".</p>
<pre><code>exit</code></pre>
<pre><code>netsh interface teredo set state enterpriseclient</code></pre>
<p>Optional IF YOUR COMPUTER ISN'T IN DOMAIN! Enterpriseclient can be replaced with server or default.</p>
<pre><code>regedit</code></pre>
<p>Browse to HKEY_LOCAL_MACHINE</p>
<p>and create a new DWORD (right click somewhere in the middle of window) and name it as "AddrConfigControl". It should have value 0 by default, if it doesn't, set the value as 0.</p>
