Eu tenho uma máquina virtual Linux / Boot2Docker em execução no VirtualBox no Windows 7 Pro. Não consigo fazer ping ou acessar a VM pelo Windows. (No entanto, o ping do meu Windows IP da VM funciona bem.) O tracert em execução parece mostrar que ele está procurando pela VM na LAN em vez do adaptador VirtualBox, mas parece que a tabela de roteamento deve rotear os pacotes corretamente.
ATUALIZAÇÃO: No Gerenciador do VirtualBox, vinculei o adaptador de rede da VM ao adaptador do Windows nº2 em vez do nº3, e agora posso fazer o ping da VM a partir do Windows. Tracert ainda olha para a LAN, mas talvez seja uma pista falsa. A VM ainda não está fazendo seu trabalho real, mas isso pode ser outro problema. Vou responder a pergunta se puder confirmar isso.
Saída do tracert:
>tracert 192.168.59.103
