宿主机：
Mac OS 10.9.2
虚拟机：
[root@localhost ~]# cat /etc/redhat-release
CentOS release 6.4 (Final)
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
虚拟机是通过vagrant up启动的
port映射已经在Vagrantfile里配置
config.vm.network :forwarded_port, guest: 80, host: 9098
而且打开局域网内能够訪问
config.vm.network :public_network
问题：
宿主机无法连接到虚拟机。
解决方法：
关闭虚拟机的防火墙
[root@localhost ~]# service iptables stop
iptables: Flushing firewall rules: [ OK
]
iptables: Setting chains to policy ACCEPT: filter [ OK
]
iptables: Unloading modules: [ OK
]
