O encaminhamento de porta do VirtualBox não está funcionando (HTTP: no, ssh: yes) [closed]

Question

Eu tenho o VirtualBox 4.3.26 (mais novo como agora) no Win7 e um convidado CentOS7. Eu habilitei o encaminhamento de porta para SSH e HTTP

Eu posso ssh no guest do host use putty por ssh 127.0.0.1:2222 , mas não consigo acessar o guest web server do host por http://127.0.0.1:3000

Answer 1

Eu tive os mesmos sintomas com um convidado do Centos 7 e um host do Windows 10. Acabou o firewall no convidado foi o problema.

O problema foi resolvido depois:

sudo systemctl stop firewalld
