The ipv4 connection works

What is needed to get the ipv6 connection?

You really should be using the "actual" ip6 address and not the link address.

The router shows multiple ipv6 addresses for the device. How to distinguish which one is actual?

IPv6 Address     2600:1702:4860:9dd0:c210:8c59:6c38:52fd
Type     slaac
Valid Lifetime     3600s
Preferred Lifetime     3600s
IPv6 Address     2600:1702:4860:9dd0:21d:60ff:fe35:b813
Type     slaac
Valid Lifetime     3600s
Preferred Lifetime     3600s
IPv6 Address     fd2e:cb3b:f005::ec1
Type     slaac
Valid Lifetime     forever
Preferred Lifetime     forever
IPv6 Address     fe80::1eb5:75df:b84:98d1
Type     slaac
Valid Lifetime     forever

Can you not login to 192.168.1.239 and run the "ip add show" command to see what the address is?

Web interface. It shows

IPv6 IP Address

fe80::200:1eb5:75df:b84:98d1 , 2600:1702:4860:9dd0:21d:60ff:fe35:b813/64

exports configuration is "*"
