一、VPN概述  
1.**VPN** : Virtual Private NetWork(虚拟专用网络)  
2.功能 : VPN在因特网(Internet)上开辟一条**安全的隧道**，以保证两个端点（或两个局域网）之间的安全通信。  
3.分类(按应用场合)  
(1)远程访问VPN

(2)网关-网关VPN

> 本文基于windows2003实现网关-网关VPN

二、实现过程  
1.网络架构  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzQ3NzAwOQ_size_16_color_FFFFFF_t_70_pic_center 2]  
故VirtualBox需新建5台虚拟机：  
ClientA、ServerA、Router、ServerB、ClientB；如下图所示：

2.创建4个虚拟网卡并配置1

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzQ3NzAwOQ_size_16_color_FFFFFF_t_70_pic_center 4]  
3.5台虚拟机分别分配虚拟网卡、配置IP地址、子网掩码、默认网关等  
(1)以ClientA为例  
①启动系统前，分配虚拟网卡  
![在这里插入图片描述][20201102132148812.png_pic_center]

②启动系统后，开始->控制面板->网络连接->本地连接->属性

②双击红色箭头所指(即 : Internet 协议)

> 注意：默认网关通过“高级”进行配置

(2)其他4台虚拟机配置情况  
**ServerA** :  
①分配虚拟网卡  
![在这里插入图片描述][20201102132257751.png_pic_center]

②本地连接

**Router** :  
①分配虚拟网卡  
![在这里插入图片描述][20201102132349417.png_pic_center]  
②本地连接  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzQ3NzAwOQ_size_16_color_FFFFFF_t_70_pic_center 9]  
③本地连接2

**ServerB** :  
①分配虚拟网卡  
![在这里插入图片描述][20201102132424250.png_pic_center]  
②本地连接![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzQ3NzAwOQ_size_16_color_FFFFFF_t_70_pic_center 11]  
③本地连接2  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzQ3NzAwOQ_size_16_color_FFFFFF_t_70_pic_center 12]  
**ClientB** :  
①分配虚拟网卡  
![在这里插入图片描述][20201102132522583.png_pic_center]  
②配置默认网关  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzQ3NzAwOQ_size_16_color_FFFFFF_t_70_pic_center 13]  
(3)正确完成上述配置，4个局域网内的计算机可互相ping同

4.创建ServerA和ServerB的IPSec策略  
5.配置远程访问VPN服务器  
6.验证结果
