我只需要能够从主机调用客户端上的服务，反之亦然，不幸的是我无法让它工作。
主机：Windows 7 专业版
客户端：Windows 7 Professional，带有 Guest Additions 4.3
我已经设置了仅主机网络。
主机 ipconfig：
Ethernet adapter Ethernet:
Link-local IPv6 address . . . : fe80::2901:db57:33a3:d585%11
IPv4 Address: 192.168.1.150
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.250
Ethernet Virtualbox Host-only Network:

客户端 ipconfig：
IPv4 Address: 192.168.56.101
Subnet Mask: 255.255.255.0

客户端上的防火墙已关闭，并且没有防病毒软件。当我尝试从客户端 ping 主机时，它显示
ping 192.168.56.1
Reply from 192.168.56.101: Destination host unreachable
从主机 ping 客户端时出现类似消息。我想问一下问题可能出在哪里。如能提供任何建议我将不胜感激。
