Try ping6

C:\Users\****>ping -6 ipv6.google.com

Pinging ipv6.l.google.com [2a00:1450:4017:806::200e] with 32 bytes of data:

Ping statistics for 2a00:1450:4017:806::200e:

Is this what you mean?

4

ping6 on the OpenWrt router, which is what you posted the screenshot of.

5 
root@OpenWrt:~# ping6 ipv6.google.com
PING ipv6.google.com (2a00:1450:4017:806::200e): 56 data bytes

it's stuck at this point.

6

CTRL-C to stop it.

Use the same endpoint in the screenshot (openwrt.org).

7 
PING openwrt.org (2a03:b0c0:3:d0::1af1:1): 56 data bytes
^C
--- openwrt.org ping statistics ---
15 packets transmitted, 0 packets received, 100% packet loss

i prematurely ended it.

8

OK...

So run -

ping6 2a03:b0c0:3:d0::1af1:1

9 
PING 2a03:b0c0:3:d0::1af1:1 (2a03:b0c0:3:d0::1af1:1): 56 data bytes
^C
--- 2a03:b0c0:3:d0::1af1:1 ping statistics ---
26 packets transmitted, 0 packets received, 100% packet loss

btw sorry if i'm being a burden to you with my ignorance here.

Your running ping ...instead of ping6 on OpenWrt.

Copy and paste this line -

ping6 2a03:b0c0:3:d0::1af1:1

Run it in OpenWrt.

In Windows, it's ping -6, so -

ping -6 2a03:b0c0:3:d0::1af1:1

11 
ping -6 2a03:b0c0:3:d0::1af1:1

Run it with ping6 on OpenWrt...as shown above.

I suspect that DNS is wrong for the WAN6 interface.

13 
root@OpenWrt:~# ping6 2a03:b0c0:3:d0::1af1:1
PING 2a03:b0c0:3:d0::1af1:1 (2a03:b0c0:3:d0::1af1:1): 56 data bytes

i really type in "ping6" but it translates into "PING" while pinging

Run the following in SSH -

ubus call system board

and

ls -l /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/* ; head -n -0

ls -l /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/* ; head -n -0 /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/*

Post results.

Where did you get the nameservers?

What do you mean by "where" ? Aren't they ISP given? I didn't do anything specifically about them.

Are you on turk.net?
