My Ubuntu client host is working very well. My tunnel endpoint is my Netgear router and radvd is running on the router. Ubuntu picked up on everything, automagically.

However, my Win 7 host cannot establish DNS to IPv6. It has acquired a valid IPv6 address via radvd and it can successfully "ping -6" to IPv6 web site names. But, using either MSIE or Chrome web browsers, it cannot surf to those sites.

I found using netsh commands that it had no DNS assigned for IPv6. I tried and tried to get it to pick up the one from my router, as Linux is apparently doing. But nothing would work.

So, I finally assigned a static dns of 2001:470:20::2, as given on my Tunnel Details page. It took that, but I still cannot surf.

What else do I need to try?

Thanks,
Tim

Never mind. Stupid Windows. Even though it was picking up and showing the changes to the network, I still had to reboot for them to become effective.

interesting.  i was under the impression that windows couldnt get dns info from radvd

Well, actually my last reply pertained to where I had statically set it to 2001:470:20::2, but out of curiosity I set it back to Automatic, rebooted again, and it still works. So, it is either getting it from radvd or some other way through the router.

try removing it via the command line, rebooting, and then see what happens.

radvd is able to distribute a recursive DNS list specified in RFC6106 - I was surprised as well when I learned it since everyone seemed to say you had to use the O flag in RA's to point to a DHCPv6 server which I don't have. (yet)

Here's an example:

Yeah, I know RADVD can transmit, but as I say, I was under the impression that Windows did not accept the DNS information.
