Considere o seguinte:
- Meu ISP tem IPv6 nativo.
- Quando eu conecto diretamente na porta ethernet da minha placa-mãe, tenho conectividade IPv6, tudo é configurado automaticamente e funciona bem.
- Mas quando eu conecto meu roteador, não tenho IPv6.
- E a parte mais interessante: eu tenho ferramenta de rede no meu roteador, e parece que o roteador pode se comunicar com o mundo exterior, porque eu posso fazer algo assim:
..

O roteador é Asus RT-N56U (firmware 3.0.0.4.374_979 [latest]) e suporta IPv6.
Para ser honesto, não entendo qual é o problema - eu tenho IPv6 nativo, o roteador suporta IPv6 e parece estabelecer a rede correta. No entanto, nada funciona.
Quando estou conectado diretamente à Internet, tenho as seguintes configurações no meu PC:

Tudo parece bem. Eu posso pingar meu roteador:
ping fe80::da50:e6ff:fe95:e731
