网络安全技术的快速发展，使目前流行的单层防火墙产品不能从根本上满足实际应用的需求。多层防火墙系统结合不同防火墙的技术和安全策略，包括包过滤技术、应用级网关技术、电路级网关技术、状态检测技术和地址翻译技术等，并用不同的方法和技术将它们整合在一起，创建一个比单一防护更有效的综合防护系统，达到安全防护的目的。

With the fast development of network security technology, current single level firewall products can not satisfy the real application requirement. Combining different firewall security strategies and technologies, such as packet filtering, application level gateway, circuit level gateway, state detection and address translation, multi-level firewall systems create a more effective comprehensive defense system than single level ones.
