Algum problema estranho aqui, eu tenho um endereço ipv6 por DHCP, no entanto, o ping ipv6.google.com deixa a rede inacessível. Outras pessoas na mesma casa usando o windows7 tem o ipv6 funcionando bem. Então, parece existir algum erro na minha configuração do Ubuntu. BTW, há vmware instalado no meu computador, e meu windows7 no vmware também pode obter endereço ipv6 e funcionar bem (usando rede em ponte).
Eu vou dar algumas informações aqui.

Então, alguém tem idéias?
