IPv6 accessibility and Hitron Router

For my Hitron CODA-4582U Router, this is the best I can find and come up with -

However, trying to connect from internet failed:

Immediate connect fail for 2607:9880:3627:ffa4:92b1:xx:xx:681f: Network is unreachable

What would be the problem? Could it be --

• The Hitron Router configuration looks so different from Website accessible via IPv6 is not accessible from outside of my network that I don't know if I've configured it correct or not.
• Moreover, my machine is behind my ISP's NAT, i.e., it doesn't have a direct public IPv4 connection.

Or something else?

Or, maybe testing from Azure is not OK? I cannot even get to google via IPv6 testing from Azure:

$ curl -v6
* Rebuilt URL to:
* Trying 2607:f8b0:4004:804::200e...
* TCP_NODELAY set
* Immediate connect fail for 2607:f8b0:4004:804::200e: Network is unreachable
* Closing connection 0
curl: (7) Couldn't connect to server

So maybe my IPv6 is in fact working? How can I test its connectivity? Pls help.

Since you cannot even connect to Google, it appears IPv6 is not correctly set up on your Azure VM or Azure may have intermittent network trouble.

I found ipv6scanner.com which lists correct information for me, for both IPv4 and IPv6 (I have full dual stack connectivity).

Your router configuration looks correct. So unless your ISP is blocking all incoming unsolicited traffic, it should work.
