F1060 GRE OVER IPSEC典型组网配置案例
组网及说明
组网说明：
本案例采用H3C HCL模拟器的F1060防火墙来模拟GRE OVER IPSEC 的典型组网配置。内网和外网在网络拓扑图中已经有了明确的标识。FW1与FW2均为各自内网的出口设备，提供NAT地址转换的服务。为了内网1和内网2能跨越外网实现通信，因为在FW1和FW2之间采用GRE V**建立隧道，同时为了保证数据传输的安全性，将ipsec嵌入到GRE V**隧道中。
配置步骤
1、按照网络拓扑图正确配置IP地址
2、FW1配置NAT，并配置默认路由指向ISP
3、FW2配置NAT，并配置默认路由指向ISP
4、FW1与FW2建立GRE V**隧道
5、在GRE V**隧道的基础上在嵌套IPSEC
