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 ***建立隧道，同时为了保证数据传输的安全性，将ipsec嵌入到GRE ***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 ***隧道

5、在GRE ***隧道的基础上在嵌套IPSEC
