Estou usando o Debian 6.0 de 64 bits ( squeeze ) a partir de um host VirtualBox de 64 bits do Windows 7, mas não consigo ping security.debian.org
do guest ou o host do Windows. Por exemplo, do convidado do VirtualBox, como root:

Na verdade, VirtualBox à parte, não consigo navegar pelos navegadores do Windows para a maioria dos sites do Debian, incluindo o link . Meu laptop se conecta a um roteador sem fio de rede doméstica comum, com os seguintes detalhes de conexão de rede:

Pelo que li sobre problemas de conexão com security.debian.org, o IPv6 pode atrapalhar e você precisa alterar a preferência para o IPv4 de alguma forma. Eu tentei modificar /etc/gai.conf
para usar precedence ::ffff:0:0/96 100
(como sugerido aqui ), mas sem sorte. Preciso desativar o IPv6 do host do Windows? Existe um site navegável IPv4 alternativo para security.debian.org? Qualquer outra coisa que valha a pena tentar?
