How can I access the server on the external network without an IPv4 public network address?

How to configure public network ipv6 access?

The current situation:
The test of the server in the IPv6 test shows that ipv6 is successful. Other machines in the LAN can access the server through http://[ipv6], and the “Welcome to nginx!” interface is displayed, indicating that the LAN is normal.
Then, access http://[ipv6] through the machine on the external network (the ipv6 has been tested successfully), but it is unsuccessful

What could be the reason please? How can I access the server on the external network without an IPv4 public network address? Thanks!

Hi, did you set a firewall exception or something in your router? It’s a bit like NAT for ipv4.
