问题描述：

防火墙配置了NAT 出方向的动态转换，但在测试网络通道时，网络配置没有生效，是不是我配置的有问题

组网及组网描述：

对齐方式靠左居中靠右组网要求：通信相关部门分配了ip地址：10.143.50.130-10.143.50.158，网关10.143.50.129，掩码255.255.255.224 。因网络IP分配的不够，我自己将所有的服务器组了私网，地址段为172.16.100.0，计划通过nat动态转换，将172.16.100.0段的设备和网络上其余设备互通起来。防火墙为F100-M-G2,内网口为1/0/5,地址配置为172.16.100.2。外网口为1/0/4,地址配置为10.143.50.130配置的防火墙信息如附件

防火墙要配置域间策略或安全策略，同时接口也需要加入安全域。

已经配置了简单的trust到untrust的域间策略
