I normally run IPv6 on my network and have since May 2010. On booting that firewall computer, one thing that happens is the 6in4 tunnel starts up. Until it's up, that computer relies on the 8.8.8.8 DNS. Once the tunnel is going, the IPv6 DNS addresses work. I have also tried using just 8.8.8.8, but the problem remains. I also tried disabling IPv6 on that computer and again no difference.
---- FWIW, what you are doing was the advice when IPv6 was introduced, but it was changed. The advice now, is to prefer an end-to-end 4-4 connection over a 4-6-6-4 as the latter introduces considerable inefficiencies and slowdowns to the net as a whole. If you really have a native 6-6, that's preferred, but a 6-6 that is really a disguised 4-4 is wasting BW.
