I can't ping or lookpup any ipv6, help would be appreciated.

So what you're saying is you have a tunnel issue? I'm going to guess you can't even ping the he side of your tunnel?

[Gorovoro]

you mean like this?

He means the HE IPv6 address of the tunnel. When you ran the Windows commands to bring up the tunnel, did you use 10.0.0.2?

-Edit- my bad, didn't see your code window had a scrollbar.

[Gorovoro]

I use my own script which i've created using several guides etc.

What happens when you query 8.8.8.8 or 8.8.4.4 or 2001:470:20::2 or 74.82.42.42 for AAAA records of hosts like ipv6.google.com?

And what happens when you query 10.0.0.138 for the same record? I Ask because that appears to be your only listed DNS server for queries.

[Gorovoro]

It seems that only 10.0.0.138 which is my router doesn't answer, also i have the static dns servers in my router set to google that is 8.8.8.8 and 8.8.4.4 so this doesn't make sense to me.

What is 10.0.0.138? Some sort of NAT appliance? There have been some make/models out there that are weird and don't return AAAA replies. You could try having it hand out the Google DNS IPs instead of itself.

[Gorovoro]

10.0.0.138 is my router it's a dlink router that until recently worked just fine with my tunnel for the last 3 years
How do i set it to hand out google?

[Gorovoro]

Ok last update
it looks like my router has gone insane for some reason and choose to ignore the DNS i gave him or something, trying to set it manually again or importing old configuration changed it back but it's as if nothing has changed meaning it still didn't work.

so finally i choose to set it on the windows side i.e. in the tcp\ip connection settings in my connection and it instantly fixed all issues.

Thanks for all you help.

[broquea]

Has the Dlink been rebooted at all? I don't just mean the services, but actually rebooted/powercycled. Maybe some sort of failure that needs it cycled.

[Gorovoro]

Of course i tried rebooting i also tried factory reset, restoring backup settings and more. but it still didn't work for some reason.
