1. 前言
学习华为防火墙IPsec双机实验记录
ensp拓扑链接：拓扑
防火墙登录账号都为admin
密码为Huawei@123
2. 拓扑
总部：
两台防火墙 采用双机部署，分别连接到ISP1、ISP2
总部两台防火墙的 ISP1 出口是 G0/0/3，连接 ISP2 的出口是 G0/0/5，缺省情况下，流量走 FW1 的 G0/0/3 接口
两台防火墙 作为内网用户的上网网关
两台防火墙 需要基于双机双出口与两个分公司分别建立 IPSec VPN。
分公司1：
路由器NAT-Device作为NAT设备，连接到ISP3
出口防火墙Fw3作为内网用户的上网网关，以及与总部对接IPSec VPN。
分公司2：
出口防火墙Fw4连接到ISP4，作为内网用户的上网网关，以及与总部对接IPSec VPN。
3. 需求
链路故障：
- FW1
连接 ISP1 链路故障，但是 ISP1 未故障，流量走 FW2 的 G0/0/3；- FW1 连接 ISP1 链路未故障，但是
ISP1 故障，流量走 FW2 的 G0/0/5；- FW1
连接 ISP1 链路恢复，ISP1 恢复，流量走 FW1 的 G0/0/3；
设备故障：
- FW1 正常情况下，流量走 FW1 的 G0/0/3；
- FW1 设备故障，流量走 FW2 的 G0/0/3；
- FW1 及 ISP1 设备故障，流量走 FW2 的 G0/0/5
4. 解法
4.1 思路
总部
IP-Link
- 在Fw1、Fw2上开启IP-Link探测功能，探测连接到IPS1的网络，当ISP1网络发生故障，可以及时发现故障。
双机热备
- 在Fw1、Fw2配置双机热备，采用主备备份模式，Fw1作为主设备、Fw2作为备设备。同时配置VGMP组监控接口和IP-Link状态，确保在遇到故障的时候实现快速切换。1. 配置VGMP组监控连接到ISP1、ISP2、内网的接口2. 配置VGMP组监控连接到ISP1的网络，即关联上一步的IP-Link
- 在Fw1、Fw2配置部署VRRP备份组：1. Fw1、Fw2连接到ISP1的接口加入到同一VRRP备份组中，虚拟IP地址配置为ISP1的公网地址，同时启用虚拟MAC地址功能。2. Fw1、Fw2连接到ISP2的接口加入到同一VRRP备份组中，虚拟IP地址配置为ISP2的公网地址，同时启用虚拟MAC地址功能。3. Fw1、Fw2连接到内网的接口加入到同一VRRP备份组中，虚拟IP地址配置为内网网关地址，同时启用虚拟MAC地址功能。4. 因为F1作为主设备，所以Fw1的VRRP备份组的状态都设置为active。5. 因为F2作为备设备，所以Fw2的VRRP备份组的状态都设置为standby。
IPsec
- 总部对接IPSec VPN的分公司，存在对端为 非固定公网IP和固定公网IP的情况，所以总部对接非固定公网IP的Fw3采用IPSec策略模板方式，对接固定公网IP的Fw4采用IPSec策略方式。
- 根据总部和分部需要互访的流量，使用高级ACL定义 需要 受IPSec VPN保护 的感兴趣流。
- 配置IKE提议、IPSec提议，根据用户需求配置安全参数，确保两端参数一致。
- 配置针对Fw3的IKE Peer。使用预共享密钥进行认证，引用IKE提议，由于对端为非固定公网IP，无需配置对端IP地址，但是需要开启NAT穿越功能。
- 配置针对Fw4的IKE Peer。使用预共享密钥进行认证，引用IKE提议，配置对端IP地址。
- 配置针对Fw3的IPsec策略模板。引用感兴趣流、IPSec提议、Fw3的IKE Peer，配置本端地址。
- 配置针对从ISP1和ISP2到达Fw4的2个IPsec策略。引用感兴趣流、IPSec提议、Fw4的IKE Peer，配置本端地址、对端地址。
- 将IPsec策略模板引用到2个IPsec策略中。切记 IPsec策略模板 的序列号 一定要大于 IPsec策略 的序列号。
- 分别在两个出接口调用对应的IPsec策略。
- 由于配置了双机热备，只需在主墙配置，配置会自动同步到备墙。
路由部署
- 根据需求，需要配置两条缺省路由，一主一备： 1. 主路由为去往ISP1，并绑定IP-Link “to_isp1”，实现ISP1故障时的路由快速切换。2. 备路由为去往ISP2。
分公司(Fw3 动态公网IP)
IPsec
- 根据总部和分部需要互访的流量，使用高级ACL定义 需要 受IPSec VPN保护 的感兴趣流。
- 配置IKE提议、IPSec提议，根据用户需求配置安全参数，确保两端参数一致。
- 配置针对总部ISP1和ISP2的两个IKE Peer。使用预共享密钥进行认证（需要与总部一致），引用IKE提议，由于本端为非固定公网IP，需要开启NAT穿越功能。在ISP1的IKE Peer中，对端IP地址为总部连接到ISP1的VRRP备份组虚拟IP地址；在ISP2的IKE Peer中，对端IP地址为总部连接到ISP2的VRRP备份组虚拟IP地址。
- 配置针对总部ISP1和ISP2的两个IPsec策略。引用感兴趣流、IPSec提议。对接总部ISP1的IPsec策略中，调用ISP1的IKE Peer；对接总部ISP2的IPsec策略中，调用ISP2的IKE Peer。
- 配置两个tunnel接口，分别为tunnel1和tunnel2，加入到与外网侧物理接口相同的安全区域中，协议类型为IPSec，同时借用外网侧接口的IP地址。Tunnel1作为主隧道，调用对接总部ISP1的IPsec策略；Tunnel2作为备隧道，调用对接总部ISP2的IPsec策略
IP-Link
- 在Fw3上开启IP-Link探测功能，探测 总部 连接到ISP1 所在的 VRRP备份组虚拟IP地址，当发生故障时，可以及时发现故障。
路由部署
- 配置一条到达运营商的缺省路由。
- 配置两条到达 总部内部网络 的路由，一主一备： 1. 主路由：下一跳指向Tunnel1，并绑定IP-Link“to_ZongBu_isp1”，实现总部ISP1故障时的路由快速切换。2. 备路由：下一跳指向Tunnel2。

4.4 流量走向诉求描述
- 当FW1 连接 ISP1 链路故障 或者 设备故障，但是 ISP1 未故障。可以通过VRRP感知故障，并联动双机热备 触发防火墙主备切换，即Fw2成为主墙。此时FW2上 主用缺省路由 绑定的 ip-link isp1并未感知ISP1网络出现故障，流量通过去往ISP1的G0/0/3口转发，且通过双机热备技术 同步状态会话表项，保证业务不中断。
