环境基本如上

目标，从windows可以ping通docker容器

如果此时在宿主机windows中ping Docker容器是ping不同的，因为在宿主机上没有通往172.18.0.0/16网络的路由，宿主机会将发往172.18.0.0/16网络的数据发往默认路由，这样就无法到达容器。

解决方法：

　　1. 首先要保证在虚拟机中能够连接到Docker容器中，用ping测试是否通畅

　　2. 关闭虚拟中的防火墙： systemctl stop firewalld.service

　　3. 打开宿主机（windows）的cmd,在其中添加通往172.18.0.0/16网络的路由。

　　通往172.18.0.0/16网络的数据包由192.168.1.101来转发

route print 172.18.0.0

route add 172.18.0.0 mask 255.255.0.0 192.168.1.101

配置完成！
