SSH&ping在vm之间工作，telnet和curl不工作

我有VMWare Fusion和两个运行CentOS 6.7的虚拟机，我正在尝试在它们的服务器和工作站上部署Chef。Ping和ssh在两个vm之间工作得很好，但当我打开客户端列表时，它会说找不到到到主机的路由。Curl和telnet也不起作用。一些信息：在OS X Yosemite上运行VMWare Fusion，禁用防火墙，两个虚拟机上的网络设置与我的Mac共享。nestat-puntal | grep nginx服务器上的收益率：

ifconfig：

错误：

这是一种蛮力解决方案，但我禁用了iptable_过滤器模块并禁用了selinux。现在可以工作。

服务iptables状态？
