Three types of network card (host, bridge, NAT) mode under VMware

Three types of network card (host, bridge, NAT) mode in VMware Preface:

Recently when learning to use Wireshark to grab a bag, a friend encountered a thorny problem:
The two operating systems on the virtual machine cannot communicate with each other and cannot crawl to both packets that access HTTP
Think of its solution, tangled for a long time, understand is the two System network card mode is not the same as the reason for communication.
This only found that they do not have a clear understanding of the three models, hurriedly to learn.

One. Bridging mode:

：

物理机上有一个自身的网卡，虚拟机虚拟一个虚拟网卡，两者可以通过虚拟出的交换机连接到外网。

Two. Nat Mode:

：

物理机上有一个自身的网卡，和虚拟NAT设备直练。虚拟NAT设备与虚拟DHCP服务器两者相连，可以实现访问外网的功能。

Three. Host mode only:

：

物理机上有一个自身的网卡，有两个虚拟机虚拟出的虚拟网卡1和2，网卡1和2可以相互通信，但是不能访问外网。
