抱歉，几个月前非常忙，不知道是不是已经得到解决。或者，你可以用这个项目中的 Vagrantfile 来重现你的问题吗？这样我就可以用 vagrant up 启动虚拟机并登录进去以后就能看到你的问题了。
在当前的 Vagrant 虚拟机环境里，是能够验证容器之间是互通的。有另外一个 issue #105 遇到和你同样的问题，我目前感觉可能是因为防火墙中的其他规则阻止了容器间的访问。你可以修改 Vagrantfile 在大概108行那大段 shell 的最后来重现你的问题。

应该是容器访问主机的映射端口被拦了，我的测试情况如下：
| 容器--容器 | 通过 172.17.0.x:port | ok |
| 容器--容器 | 通过 172.17.0.1:port(端口映射) | 无法访问 |
| 容器--主机 | 通过 172.17.0.1:port(直接部署在主机上的服务) | 无法访问 |
| 主机--容器 | 通过 172.17.0.x:port | ok |
| 主机--容器 | 通过 172.17.0.1:port(端口映射) | ok |
然后执行 ufw allow from 172.16.0.0/12 to 172.17.0.1 proto tcp后，容器到主机172.17.0.1可以正常访问。但是没搞懂172.17.0.1是包含在172.16.0.0/12这一段中，按理说应该不会存在这个问题的，希望作者大大能解答一下。
