无法将CentOS VM连接到Internet(NAT连接)

Question

因此,在过去一天与VMWare网络巨头作战之后,我决定让步并寻求帮助.我在Windows 7上运行的CentOS 6映像使用VMWare Workstation 8.0.2 build-591240上的NAT,由于某种原因,我无法再使用静态IP地址连接到Internet.这似乎只适用于静态,而不是DHCP,它告诉我它是:我的Windows 7操作系统上的某个程序阻止了该IP地址的连接,或者我的配置在CentOS映像上发生了一些奇怪的事情.

我不知道这是否是由于yum更新,所以我尝试重新安装VMWare工具.这似乎没有解决问题.我也尝试过以下方法:

1. 确保VMnet连接已连接(愚蠢,但必须检查...我也可以使用DHCP连接到Internet)
2. 确保Windows上的防火墙允许VMware连接到Internet
3. 我已经看到/读过Windows有时会阻止ping请求,所以我尝试在Firefox中访问www.google.com,这得到了"服务器未找到响应"...所以我必须为DNS做些不同的事情吗？
4. 我检查了我的Windows机器的注册表,我只有一个默认网关的条目

就像我说的那样,这似乎突然发生了.图像可以连接到互联网之前没有问题.是否有人知道可能导致此问题的CentOS更新？我在下面添加了我的配置以节省一些调试周期:

Answer 1

最好的选择是让它从DHCP自动获取IP:

dhclient -v

这将让centos自动获得一个ip.
