2. Input Parameters

The following request parameter list only provides API request parameters. Common request parameters need to be added when the API is called. For more information, refer to Common Request Parameters. The Action field for this API is ModifyVpnConnEx.

Parameter Name Required Type Description
vpcId Yes string Virtual private cloud ID, which can be vpcId or unVpcId. unVpcId is recommended. For example: vpc-03vihbk9. Can be queried via the API DescribeVpcEx.
vpnGwId Yes String VPN gateway ID assigned by the system, which can be vpnGwId or unVpnGwId. unVpnGwId is recommended.
vpnConnId Yes String VPN tunnel ID assigned by the system, which can be vpnConnId or unVpnConnId. unVpnConnId is recommended.
vpnConnName No String Tunnel name; up to 60 characters.
preSharedKey No String Pre-shared private key.
userGwCidrBlock.n No Array CIDR address of the peer IP address range, multiple values can be entered. Specifies the IDC IP address range the VPC can communicate with, later upgraded to spdAcl (finer granularity). Either userGwCidrBlock or spdAcl must be entered.
spdAcl.n No Array SPD rule group. You can specify which IP address range in the VPC can communicate with which IP address range in your IDC, upgraded from userGwCidrBlock. Either userGwCidrBlock or spdAcl must be entered. See the product instruction for details.
IKESet.n No Array IKE configuration (Internet Key Exchange). IKE is provided with a self-protection mechanism. The network security protocol is configured by the user.
IPsecSet.n No Array IPSec configuration. The IPSec secure session configuration is provided by Tencent Cloud. See VPN Connection-IPSec Configuration for details.
