Eu posso acessar o apache com o URL http://192.168.13 , bem como http://127.0.0.1 ou pelo nome do host, mas não consigo obtê-lo remotamente. Eu estou usando o Windscribe VPN. Eu tentei whatismyip website e, em seguida, escrito IP + porta 80, mas não consigo acessar remotamente.
Também verifiquei a porta em ping.eu and canyouseeme.org , mas mostrando fechada
== > Um isso é muito importante que quando eu verificar como:
$ netstat -tanp |grep 80
tcp 0 1 10.114.78.190:45684 89.38.99.102:80 LAST_ACK -
tcp6 0 0 :::80 :::* LISTEN 9655/apache2
1) Em seguida, verifique os sites mostrando Success mensagem para este IP 89.38.99.102 . De onde veio esse IP no meu pc?
2) 89.38.99.102:80 correu mas deu Forbidden message
Por favor, informe como eu posso abrir a porta 80 no meu pc Linux e posso acessá-la remotamente de qualquer outro computador que tenha conexão com a internet
Obrigado antecipadamente
