示例：在 Amazon VPC 之间的 vSRX 虚拟防火墙上配置 VPN
此示例说明如何在不同 Amazon VPC 上的两个 vSRX 虚拟防火墙实例之间配置 IPsec VPN。
开始之前
确保您已在 Amazon VPC 中安装并启动了 vSRX 虚拟防火墙实例。
有关其他信息，请参阅 SRX 站点到站点 VPN 配置生成器 和 如何对关闭或未激活的 VPN 隧道进行故障排除 。
概述
您可以使用 IPsec VPN 通过两个 vSRX 虚拟防火墙实例来保护两个 Amazon VPC 之间的流量。
vSRX1 VPN 配置
程序
分步过程
要在 vSRX1 上配置 IPsec VPN，请执行以下操作：
在配置编辑模式下登录到 vSRX1 控制台（请参见 使用 CLI 配置 vSRX。
设置 vSRX1 收入接口的 IP 地址。
set interfaces ge-0/0/0 unit 0 family inet address 10.0.0.10/24 set interfaces ge-0/0/1 unit 0 family inet address 10.10.10.10/24 set interfaces st0 unit 1 family inet address 10.0.250.10/24
设置不信任安全区域。
set security zones security-zone untrust screen untrust-screen set security zones security-zone untrust host-inbound-traffic system-services https set security zones security-zone untrust host-inbound-traffic system-services ssh set security security-zone untrust interfaces ge-0/0/0.0 set security security-zone untrust interfaces st0.1
设置信任安全区域。
set security zone trust host-inbound-traffic system-services https set security zone trust host-inbound-traffic system-services ssh set security zone trust host-inbound-traffic system-services ping set security security-zone trust interfaces ge-0/0/1.0
配置 IKE。
