我有2个VirtualBox虚拟机，其中freeDOS（1.2）作为访客，我正在尝试在它们之间建立网络连接。
首先，我试图在其中一台机器和主机之间建立连接（Windows 10）。
似乎由于某种原因，访客不回答ARP和ping请求，虽然它可以向主机发送ARP请求并使用答案来ping主机。
在VM的“网络设置”中，适配器设置为“仅主机适配器”。
这里的主机是192.168.56.1，访客是192.168.56.2
从主机ping客户端不起作用：
C:\Users\Rafi>ping 192.168.56.2
Pinging 192.168.56.2 with 32 bytes of data:
Request timed out.

Reply from 192.168.56.1: Destination host unreachable.

从客户端ping客户不起作用：
