摘　　要：高校校园网结构比较复杂，除了用户众多外，存在多个对外出口，通常使用防火墙实现与外网的通信。在防火墙上进行细致的策略路由设计，对提高出口资源利用率，保护校园网的安全非常重要。通过路由配置、地址转换、虚拟专用网、流量控制、安全防范等研究，特别是基于规则的策略路由和路由备份、路由和NAT混杂的接入模式，同一接口路由加NAT等实践，提供了一种高效可靠的校园网多出口策略路由的应用案例。The structure of campus network is complicated, including several outside interfaces apart from many users, which usually uses firewall to achieve communication with the external network. Improving the export of resource utilization and protection of the campus network security, it is very important to design detailed policy routing in firewall. Through the routing configuration, address translation, virtual private networks, traffic control, safety precautions and other research, especially Me-based policy routing and route backup, routing and NAT mixed access mode, the same interface plus NAT and other routing practices, which provides a kind of more efficient and reliable multi-export policy routing of campus network application cases.
