Estou usando o Oracle VM VirtualBox e executando uma instância do CentOS 7 nele.
Eu configurei dois adaptadores de rede para esta máquina. Um é definido no modo Somente host e o outro no modo NAT.
Eu sou capaz de SSH para a VM.
Agora também estou executando um servidor da Web nesta VM e quero acessá-lo da mesma maneira.
Mas não está funcionando dessa maneira.
Eu tentei com outras regras também
Port 3000 no Host, Port 80 no Guest.
Porta 12000 no host, porta 80 no convidado.
Com o mesmo IP no Host: 3000 no host e com o IP exato: Port on Guest.
Sem IP e porta 3000 no host e com o IP exato: Port on Guest.
Não está funcionando.
Eu sou capaz de ping também do host para a VM e vice-versa.
Eu testei a configuração do Apache HTTPD dentro do VM-
O servidor está na posição UP.
Eu usei o Lynx para acessar o site e isso também está funcionando, mas apenas dentro da VM.
Não de fora da máquina ou do sistema operacional host.

Por favor, ajude alguém.
Eu estou tentando fazer do trabalho algo realmente crucial aqui e esta é uma situação muito estúpida, onde eu sou atingido apenas em redes.
Ajude os rapazes.
Obrigado
