上一篇文章讲过了AWS GWLB如何集成FortiGate防火墙，来对流量做集中检测。上一次实验是通过AWS 控制台操作的，这里分享一下实验环境的CloudFormation代码，帮助大家快速部署一下实验环境。
这里的CloudFormation代码在Tokyo区域部署的，如果要在其他Region部署，请修改FortiGate和Windows2022Base的AMI ID（参考我之前的文章《如何寻找EC2特定版本的AMI ID》）。
这次CloudFormation是全自动化代码，堆栈运行完成以后，可以直接测试现象，不需要再做任何额外的配置。默认防火墙使用6.4.10的版本部署，如果要使用7.2.2参考第四部分修改关于防火墙的代码。

堆栈创建完成之后，会输出GWLB的弹性接口IP地址。如果手动配置Fortigate防火墙，配置geneve时需要这个信息。在CloudFormation里面，已经通过脚本自动化把这个地址抓取并且配置了。
二、查看FortiGate防火墙配置 FortiGate防火墙的配置在CloudFormation代码里面已经配置完成了，这里通过图形化界面来看一下配置结果。
首次登陆FortiGate防火墙，默认的用户名是admin，默认的密码是实例id。
我在CloudFormation代码里面，为防火墙新建了一个测试用户，用户名为labuser，密码为FSr1Lliu1qiang2long3DemoZJG5。
这里可以查看实例ID信息。
2.1 FortiGate FW1 配置 FortiGate-FW1启用了Split-VDOM，有两个VDOM，root用于防火墙管理，FG-traffic用于转发数据流量。
port1是主接口，用于转发数据流量。port2作为管理接口，用于管理流量。
静态路由配置，默认路由从geneve1和geneve2接口出去，配置本VPC CIDR网段从port1数据接口出去，下一跳指向子网网关。
因为配置了两条默认路由，有可能造成流量来回路径不一致的问题。所以通过配置策略路由，让来自geneve1的流量从genven1接口出去，来自geneve2的流量从genven2接口出去。
测试环境下，放行所有流量。
2.2 FortiGate FW2 配置 FortiGate-FW2启用了Split-Task VDOM，有两个VDOM，root和FG-traffic。
port1是主接口，用于转发数据流量。port2作为管理接口，用于管理流量。
静态路由配置，默认路由从geneve1和geneve2接口出去，配置本VPC CIDR网段从port1数据接口出去，下一跳指向子网网关。
配置策略路由，因为配置了两条默认路由，有可能造成流量来回路径不一致的问题。所以通过配置策略路由，让来自geneve1的流量从genven1接口出去，来自geneve2的流量从genven2接口出去。
测试环境下，放行所有流量。
三、现象测试 3.1 访问APP测试 连接上APP2 Window RDP桌面。可以使用我在代码里面新建的用户名labuser，密码FSr1Lliu1qiang2long3DemoZJG5进行连接。
查看防火墙连接日志信息。
3.2 防火墙抓包 FortiGate防火墙可以通过Debug packet flow [1]来查看防火墙对数据包执行的动作，这个抓包方法一般用于排错，输出的信息比较多。也可以通过自带的sniffer工具 [2]单纯的抓包，输出的信息比较简洁。
Debug packet flow
例如：这里首先暂停了之前的抓包进程，然后抓取地址包含114.114.114.114的10个报文。
1 2 3 4 5 6 diagnose debug flow trace stop diagnose debug enable diagnose debug flow filter addr 114.114.114.114 diagnose debug flow show function-name enable diagnose debug flow trace start 10
也可以通过协议来进行过滤，这里只查看icmp协议的报文。
1 2 3 4 5 6 diagnose debug flow trace stop diagnose debug enable diagnose debug flow filter proto 1 diagnose debug flow show function-name enable diagnose debug flow trace start 10
运行的效果如下：
自带sniffer工具抓包
例如，这里抓取来自port1端口，端口号为6081的报文，其实就是GENVEN报文。
1 FGT-GWLB-1 (FG-traffic) # diagnose sniffer packet port1 'port 6081'
例如，这里抓取来所有的icmp报文。
1 FGT-GWLB-1 (FG-traffic) # diagnose sniffer packet any icmp 4
抓包命令结果如下：
可以利用sniff抓包来确认流量目前走哪一台防火墙，然后stop这个防火墙实例，查看流量多长时间能够切换成功，测试防火墙的高可用切换。我测试大致会在40秒左右切换成功。
四、部署Fortigate7.2.2版本代码参考 上述的CloudFormation代码中FortiGate防火墙的开机启动配置，是基于FortiGate6.4.10版本配置的。如果选择7.2.2版本部署，防火墙无法加载对应配置，可以将下面的代码替换上面关于防火墙的部分。
