1 配置需求及说明

1.1  适用的产品系列

本案例适用于软件平台为Comware V7系列防火墙：F100-X-G2、F1000-X-G2、F100-X-WiNet、F1000-AK、F10X0等。

1.2  配置需求及实现的效果

用户需求两台V7防火墙使用IKEV2协议对接IPSEC VPN，IP地址及接口规划如下表所示：

公司名称	外网接口	公网地址/掩码	公网网关	内网接口	内网地址/掩码
总部	0/0	1.1.1.1/24	1.1.1.2	0/1	9.9.9.0/24
分部	0/0	2.2.2.1/24	2.2.2.2	0/1	8.8.8.0/24

3 配置步骤

3.1  两端防火墙上网配置

防火墙上网配置请参考“2.3.2 防火墙外网使用固定IP地址上网配置方法”进行配置，本文只针对IPSEC VPN配置进行介绍。

3.2  总部侧创建IPSEC兴趣流匹配到分部的数据

创建IPSEC的感兴趣流，用于匹配IPSEC数据。

<H3C>system

[H3C]acl advanced 3000

[H3C-acl-ipv4-adv-3000]rule permit ip source 9.9.9.0 0.0.0.255 destination 8.8.8.0 0.0.0.255

[H3C-acl-ipv4-adv-3000]quit

创建acl 3001调用在外网接口用于排除IPSEC兴趣流不做NAT。

[H3C]acl advanced 3001

[H3C-acl-ipv4-adv-3001]rule deny ip source 9.9.9.0 0.0.0.255 destination 8.8.8.0 0.0.0.255
