可以使用用户界面和 API 对网关防火墙进行故障排除。
可以使用
NSX Manager UI 和 API 检查以下内容：
- 为给定网关启用了网关防火墙。
- 检查给定网关防火墙策略的实现状态。UI 在“防火墙策略”标题右上角旁边显示实现状态。
- 检查规则统计信息以查看是否有任何流量命中防火墙策略。
- 为规则启用日志记录以对策略进行故障排除。
网关防火墙是在 NSX Edge 传输节点上实现的。下一步是，在 NSX Edge 节点命令提示符下使用 nsxcli 命令进行数据路径故障排除，如下所示。
获取启用了防火墙的网关的 UUID

使用 UUID 获取所有网关接口
网关防火墙是为网关的每个上行链路接口实现的。确定上行链路接口，并从下面的输出中获取接口 ID。

检查网关防火墙同步状态
网关防火墙在 Edge 节点之间同步流量状态以实现高可用性。可以使用以下输出查看网关防火墙同步配置。

检查网关防火墙日志
网关防火墙日志提供网关虚拟路由和转发 (VRF)、网关接口信息以及流量详细信息。可以在 /var/log 目录中名为 firewallpkt.log 的文件中找到网关防火墙日志。
