本教程为使用 IPsec 配置的 VyOS 设备提供配置信息和示例模板。
vti <NAME_OF_VTI_INTERFACE>- 指定 IPsec 隧道的虚拟隧道接口。esp-group <NAME_OF_ESP_GROUP>- 使用特定的 ESP 策略或配置文件对通过隧道的流量进行加密。ike-group <NAME_OF_IKE_GROUP>- 使用特定的 IKE 策略或配置文件交换密钥。- 隧道两端 IPsec 隧道接口的 IP 地址应该是同一
/31或/30子网中的一对私有 IP 地址（RFC 1918），指定点对点链路。 - 此 VyOS 路由器上的 IPsec 隧道端点是
<IP_ADDR_OF_UPLINK_INTF_TO_INTERNET/WAN>。 - Cloudflare 侧的 IPsec 隧道端点 IP 地址是分配给您的账户的 anycast IP 地址之一，可在 租用的 IP ↗ 中获取。
- 此路由器配置为发起 IPsec 隧道连接。
