（一）实验简介
如图所示，总部网络A和分支机构网络B之间采用网关对网关的组网模式进行资源传输。网络A和网络B分别通过FW_A和FW_B连接到Internet，通过手工方式创建IPSec VPN隧道，提高网络通信的安全性。
网络拓朴结构
（二）实验目的
- 掌握网关对网关的组网；
- 掌握手工方式配置两个网络的IPSecVPN；
（三）实验条件
- 一台CPU支持VT技术，内存4GB以上的计算机；
- 安装eNSP模拟器B510版，导入USG6000V镜像；
- 终端工具：SecuretyCRT，Putty，Psftp，XShell等。
（四）网络拓朴图
打开ENSP软件，按如下拓朴图创建实验环境，设置地址:
- LAN1地址：10.10.10.0/24；
- LAN2地址：10.20.20.0/24；
- ISP1地址：10.1.1.0/24；
- ISP2地址：10.2.2.0/24；
实验8拓朴
（五）配置思路
- 配置LAN1/LAN2网络；
- 配置两个防火墙互联；
- 配置IPSecVPN；
（六）配置步骤
