can'；从centos虚拟机ping谷歌

最近在我的windows 7主机中安装了centos虚拟机（vm player）

• 我可以从内部网络ping我的虚拟机，没有任何问题
• 我还可以从我的虚拟机访问内部网络，而不会出现问题
• 但我的虚拟机不能访问互联网，我不能ping谷歌或任何其他外部网络

我尝试了几种解决方案，花了一个多星期的时间试图找出问题所在

配置：

• 我的虚拟机已桥接并在DHCP模式下工作：

[root@localhost~]#ifconfig

          RX bytes:4098 (4.0 KiB)  TX bytes:4098 (4.0 KiB)

[root@localhost~]#更多/etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=yes

HOSTNAME=localhost.localdomain

[root@localhost~]#**

[root@localhost~]#**

[root@localhost~]#

我可以ping我的网关，也可以ping我的DNS和代理：

[root@localhost~]#

网络接口已启动并正在运行：

[root@localhost ~]# service network status
Configured devices:
lo eth0
Currently active devices:
lo eth0

防火墙已停止：

[root@localhost ~]# service iptables status
Firewall is stopped.
[root@localhost ~]# service ip6tables status
Firewall is stopped.

还有什么？我也可以

但我无法连接到互联网

提前感谢您的帮助。

尝试ping到您的名称服务器ip地址，并尝试ping到您的网关地址。禁用搜索。。。在resolv.conf中输入行

**netstat -rn**
