  这篇记录下 nat 网络模式下虚拟机与主机的相互 ping 通。首先使用 wmware 建立一个 ubuntu 虚拟机,网络模式选择 nat 模式。然后点击虚拟网络编辑:

上面红框是关键,记录这个值,下面虚拟机设置静态 ip 要用到。

2019-01-07 10:31:40 +08:00
  打开网络适配器页面,选择 VMnet,右键->属性->Internet 协议版本 4TCP/IPV4->属性,设置 ip 地址为上面上面网关地址最后一个数改成 1比如 192.168.128.2 就要设置为 192.168.128.1,同时设置子网掩码为 255.255.255.0,默认网关不要填。我的如下:

**如果想让虚拟机能够访问主机需要关闭主机的防火墙**

## 3、ubuntu 设置
2018-10-07 17:53:22 +08:00
&emsp;&emsp;编辑/etc/network/interfaces
```bash
vim /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto ens33
# dhcp 改成static然后设置下面的address,netmask,gateway
iface ens33 inet static
address 192.168.128.129
netmask 255.255.255.0
gateway 192.168.128.2
# 设置dns
dns-nameservers 192.168.128.2
```
然后执行`/etc/init.d/networking restart`,或者重启虚拟机以启用网络设置。
## 3、验证
2019-01-07 10:31:40 +08:00
&emsp;&emsp;现在虚拟机中`ping 192.168.128.1`可以 ping 通,主机中`ping 192.168.128.129`也可 ping 通。
