Enable IPv6 in Chrome

In order for internal websites to function over DirectAccess I had to enable IPv6 DNS in Chrome.  I found that a restart of my computer was required in order to successfully access IPv4 pages with acceptable load times.

Below are the steps:

1. Open Chrome
2. Browse to  chrome://net-internals/#dns
3. Click the enable IPv6 button
4. Attempt to browse to your site.

DirectAccess Client Connectivity - Teredo state

I ran into an issue to where I was unable to get connected to my DirectAccess server due to an issue with my DA Client IPv6 settings.  It's important to note that the teredo interface state should be "qualified" when it's functioning properly.


The default client type was set to "client".  Once I changed this to "enterpriseclient" everything started working.

C:\Windows\system32>netsh interface teredo show state
Teredo Parameters
---------------------------------------------
Type                    : client
Server Name             :    (Group Policy)
Client Refresh Interval : 30 seconds
Client Port             : unspecified
State                   : offline
Error                   : client is in a managed network


C:\Windows\system32>netsh int ter set state enterpriseclient
Ok.

C:\Windows\system32>netsh interface teredo show state
Teredo Parameters

This can be configured via GPO.
