属性

属性名称	类型	必须	允许更新	描述	约束
LocalSubnet	String	是	是	需要和本地数据中心互通的VPC侧的网段，用于第二阶段协商。	多个网段之间用半角逗号（,）分隔，例如：192.168.1.0/24,192.168.2.0/24。关于IPsec连接路由模式的说明：如果LocalSubnet和RemoteSubnet均输入为0.0.0.0/0，则表示您使用目的路由模式。如果LocalSubnet和RemoteSubnet均输入具体的网段，则表示您使用感兴趣流模式。示例值：10.1.1.0/24,10.1.2.0/24。
CustomerGatewayId	String	是	否	用户网关ID。	无
AutoConfigRoute	Boolean	否	是	是否自动配置路由。	取值： true（默认值）：自动配置路由。 false：不自动配置路由。
Name	String	否	是	IPsec连接的名称。	无
EffectImmediately	Boolean	否	是	选择IPsec连接的配置是否立即生效。	取值： true：是，配置完成后系统立即进行IPsec协议协商。 false（默认值）：否，当有流量进入时系统才进行IPsec协议协商。
BgpConfig	Map	否	是	BGP的配置信息。	更多信息。请参见BgpConfig属性。说明在添加BGP配置前，建议您先了解BGP动态路由功能的工作机制和使用限制。更多信息，请参见VPN网关支持BGP动态路由公告。建议您使用自治系统号的私有号码与阿里云建立BGP连接。自治系统号的私有号码范围请自行查阅文档。示例值： `{"EnableBgp":"true","LocalAsn":"45104","TunnelCidr":"169.254.11.0/30","LocalBgpIp":"169.254.11.1"}`
RemoteSubnet	String	是	是	需要和VPC互通的本地数据中心侧的网段，用于第二阶段协商。	多个网段之间用半角逗号（,）分隔，例如：192.168.3.0/24,192.168.4.0/24。关于IPsec连接路由模式的说明：如果LocalSubnet和RemoteSubnet均输入为0.0.0.0/0，则表示您使用目的路由模式。如果LocalSubnet和RemoteSubnet均输入具体的网段，则表示您使用感兴趣流模式。示例值：10.1.3.0/24,10.1.4.0/24
RemoteCaCert	String	否	否	国密型VPN网关创建IPsec连接时，对端的CA证书。	示例值： `-----BEGIN CERTIFICATE----- MIIB7zCCAZW**** -----END CERTIFICATE-----`
IpsecConfig	Map	否	是	第二阶段协商的配置信息。	更多信息，请参见IpsecConfig属性。示例值： `{"IpsecEncAlg":"aes","IpsecAuthAlg":"sha1","IpsecPfs":"group2","IpsecLifetime":86400}`
NetworkType	String	否	否	IPsec连接的网络类型。	取值： public（默认值）：公网，表示IPsec连接通过公网建立加密通信通道。 private：私网，表示IPsec连接通过私网建立加密通信通道。

EnableNatTraversal	Boolean	否	是	是否开启NAT穿越功能。	取值： true（默认值）：开启NAT穿越功能。开启后，IKE协商过程会删除对UDP端口号的验证过程，同时实现对VPN隧道中NAT网关设备的发现功能。 false：不开启NAT穿越功能。
IkeConfig	Map	否	是	第一阶段协商的配置信息。	更多信息，请参见IkeConfig属性。
EnableDpd	Boolean	否	是	是否开启DPD（对等体存活检测）功能。	取值： true（默认值）：开启DPD功能。IPsec发起端会发送DPD报文用来检测对端的设备是否存活，如果在设定时间内未收到正确回应则认为对端已经断线，IPsec将删除ISAKMP SA和相应的IPsec SA，安全隧道同样也会被删除。 false：不开启DPD功能，IPsec发起端不会发送DPD探测报文。
