7.办公区设备可以通过电信链路和移动链路上网(多对多的NAT,并且需要保留一个公网IP不能用来转换)
创建移动网络和电信网络的安全区域
将对应接口放入相应区域并配置相应ip地址
新建NAT策略 ---- 多对多的NAT:
新建转换地址池
保留一个ip地址
为保证设备顺利转发NAT业务,需要配置安全策略
相同操作配置办公区通过移动链路上网
NAT策略:

8.分公司设备可以通过总公司的移动链路和电信链路访问到dmz区的http服务器
配置分公司防火墙:

9.多出口环境基干带宽比例进行选路,但是,办公区中10.0.2.10该设备只能通过电信的链路访问互联网。链路开启过载保护,保护國值80%
配置智能选路:
链路过载保护,设置阈值:
对于10.0.2.10 新建策略路由:
