Enable IPv6 from 1.1.1.1

Hello guys, I need your help to configure a router to work with IPv6 from 1.1.1.1.

Now I have FTTH, and this is where the problem begins, as my ISP’s DNS does not have IPv6, so I configured the Cloudflare DNS on the router, but this TP-Link router has a guide only for IPv6.
To connect to the internet I use PPPoE provided by my ISP.

And the router’s IPv6 tab has the following information that I have no idea how to configure:

IPv6 Wan Guide
Connection type: 1- Dynamic IPv6, 2- Static IPv6, 3- PPPoEv6, 4- 6to4 (if you choose 2- Static IPv6 or 3- PPPoEv6 you need to make other additional configurations)
Addressing type: 1- DCHPv6, 2-SLAAC
MTU: it already has a value of 1500
Possibility to configure IPv6 DNS manually
Hostname: it already has the router model name “TL-WR849N” by default

IPv6 Lan Guide
Autoconfiguration address type: 1- RADVD, 2- DHCPv6 server (if you choose 2- DHCPv6 server, ask to set initial IPv6 address “by default is 1”, final IPv6 address “by default is FFFE”, and renewal period “by default it is 86400”)
Enable RDNSS
Enable ULA Prefix (if enabled, ask for the ULA prefix and the size of the ULA prefix)
Type of site prefix configuration: 1- Targeted, 2- Static (if you choose 2- Static, ask to configure site prefix and site prefix size).

If you need or prefer, here is an emulator of my router’s firmware, the only problem is that it is in Portuguese because it is a version released in Brazil (https://emulator.tp-link.com/Emulator_TL-WR849N(BR)6.20/index.htm).

Thank you so much :blush::wink:

To clarify, do you have any ipv6 connectivity? You can’t connect to 1.1.1.1’s IPv6 IP at all if you have no DNS, native or otherwise. If your ISP doesn’t give you IPv6 you can’t obtain connectivity without using some paid third-party tunnels.

First, I would like to thank you for the answer.

In conclusion, my ISP’s DNS does not support IPv6. And in the IPv6 test (link), it was 0 of 10.

Thank you very much for clarifying, as I thought that IPv6 support depended only on DNS (that is, as my DNS does not support IPv6, making the exchange for CloudFlare, OpenDNS or Google, it would be supported, but here I realized that I was wrong, because it depends on the physical configuration of my ISP too, right?). But, by his explanation of tunneling, it was possible to understand superficially how it works.
