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? Pls help.

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

$ curl -v6 https://google.com
* Rebuilt URL to: https://google.com/
*   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.
