我正在开发一个门户，这个门户的主要目的是让我的所有同事（他们的机器连接到同一网络）访问该门户。
我试图重新安装我的 apache 服务器，但它仍然给我同样的错误。我正在使用 Ubuntu 16.04
我对网络的了解有限，任何帮助都会非常有用。
我安装了 virtualbox 并尝试在虚拟框中打开 google chrome 和 firefox 时测试问题，我收到以下消息：
Firefox:
Unable to connect
Firefox can’t establish a connection to the server at xxx.xxx.xx.240.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Chrome:
This site can't be reached
xxx.xxx.xx.240 is unreachable
ERR_ADDRESS_UNREACHABLE
I even tried to acess my portal using a machine that has windows as its os it it gives me this error:
Chrome on windows:
This site can't be reached
xxx.xxx.xx.240 took too long to respond
ERR_CONNECTION_TIMED_OUT
编辑：根据 Tomer Petel 的建议，这里是我的 vm 的 ifconfig :（并且由于我们办公室里的所有机器都是基于 linux 的，我也将 ubuntu 用于我的 vm）

这是我机器的 ifconfig（w/c 是门户的服务器）

长话短说，这是网络服务器 IP 配置问题。您需要通过/etc/network/interfaces而不是通过配置 Web 服务器的 IP ，ifconfig因为它在重新启动后不是持久的。看这里怎么做
