目标

介绍设备以二层透明方式接入网络时，IPSec隧道的配置方法。

组网需求

如图1所示，分支机构和总部分别通过FW_A和FW_B连接到Internet。FW_C是以二层透明方式部署在FW_B和L3SW（三层交换机）之间。用户需要在FW_A和FW_C之间建立IPSec隧道，以保护分支与总部之间进行安全通信。

enspgre隧道ipv6 ensp隧道协议配置_enspgre隧道ipv6

配置思路

FW_A作为分支机构的出口网关，采用非模板方式与总部建立IPSec隧道。
FW_C采用模板方式同FW_A建立IPSec隧道，IPSec安全策略应用在二层接口GE1/0/1上，二层接口借用VLANIF10的IP地址与分支建立IPSec隧道。

操作步骤

配置FW_A。

按照图1配置接口IP地址。

配置接口IP地址。

<sysname> system-view
[sysname] sysname FW_A
[FW_A] interface gigabitethernet 1 / 0 / 1
[FW_A-GigabitEthernet1/0/1] ip address 10.1.1.1  24
[FW_A-GigabitEthernet1/0/1] quit
[FW_A] interface gigabitethernet 1 / 0 / 2
[FW_A-GigabitEthernet1/0/2] ip address 1.1.1.1  24
[FW_A-GigabitEthernet1/0/2] quit
复制代码

将接口加入相应安全区域。

[FW_A] firewall zone untrust
[FW_A-zone-untrust] add interface gigabitethernet 1 / 0 / 2
[FW_A-zone-untrust] quit
[FW_A] firewall zone trust
[FW_A-zone-trust] add interface gigabitethernet 1 / 0 / 1
[FW_A-zone-trust] quit
复制代码

配置安全策略。

配置Trust域与Untrust域的转发策略，允许封装前和解封后的报文能通过FW_A。
