When attachment_type is set to vpc, this parameter is mandatory. When attachment_type is set to er, this parameter is optional; if both vpc_id and access_vpc_id are set, the access_vpc_id value is used. Either vpc_id or er_id must be specified. You can obtain the VPC ID by .
local_subnets	Array of String	No	Specifies a local subnet. This subnet is a cloud-side subnet that needs to communicate with an on-premises customer subnet through a VPN. A maximum of 50 local subnets can be specified for each VPN gateway. For example, a local subnet can be 192.168.52.0/24. This parameter is mandatory only when attachment_type is set to vpc.
connect_subnet	String	No	Specifies the ID of the VPC subnet used by the VPN gateway. The value is a UUID containing 36 characters. When attachment_type is set to vpc, this parameter is mandatory.

access_vpc_id	String	No	Specifies the ID of the access VPC used by the VPN gateway. The value is a UUID containing 36 characters. By default, the value is the same as the value of vpc_id. You can obtain the VPC ID by querying VPCs.
access_subnet_id	String	No	Specifies the ID of the subnet in the access VPC used by the VPN gateway. The value is a UUID containing 36 characters. When attachment_type is set to er, the subnet must have at least two idle IP addresses.

You can submit a service ticket to increase the maximum EIP bandwidth under your account. The value ranges from 1 to 1000. For details, see the EIP documentation. This parameter is mandatory only when a new EIP not binding to shared bandwidth is created. The value cannot be greater than 300 when flavor is set to Professional1. The value cannot be greater than 1000 when flavor is set to Professional2. The value cannot be greater than 500 when flavor is set to GM.
bandwidth_name	String	No	Specifies the bandwidth name of an EIP. The value is a string of 1 to 64 characters, which can contain digits, letters, underscores (_), hyphens (-), and periods (.). This parameter is mandatory only when a new EIP not binding to shared bandwidth is created. When a new EIP is used and this parameter is not set, an EIP bandwidth name in the format of vpngw-bandwidth-** is automatically generated, for example, vpngw-bandwidth-e1fa**.

**Table 5** VpnResourceTag
