推荐答案

在大多数情况下，只需将虚拟机网络适配器切换为 bridged 模式就足以从外部访问来宾计算机.

In most cases simply switching the virtual machine network adapter to bridged mode is enough to make the guest machine accessible from outside.

有时，在切换到桥接模式后(甚至在重新启动客户机之后)，客户机也可能不会自动收到与主机IP范围匹配的IP.这通常是由主机网络上的DHCP故障或配置错误造成的.

Sometimes it's possible for the guest machine to not automatically receive an IP which matches the host's IP range after switching to bridged mode (even after rebooting the guest machine). This is often caused by a malfunctioning or badly configured DHCP on the host network.

例如，如果主机IP为192.168.1.1，则访客计算机需要具有格式为192.168.1.*的IP，其中仅允许最后一组数字不同于主机IP.

For example, if the host IP is 192.168.1.1 the guest machine needs to have an IP in the format 192.168.1.* where only the last group of numbers is allowed to be different from the host IP.

您可以使用终端机(外壳)并键入ifconfig(对于Windows guest虚拟机，则为ipconfig)来检查为该客户机分配了哪些IP，并在需要时进行更改.

You can use a terminal (shell) and type ifconfig (ipconfig for Windows guests) to check what IP is assigned to the guest machine and change it if required.

如果主机和来宾IP不匹配，只需为来宾计算机设置静态IP即可解决此问题.

If the host and guest IPs do not match simply setting a static IP for the guest machine explicitly should resolve the issue.
