This topic describes the service-linked role AliyunServiceRoleForVpn of VPN Gateway.
Background information
A service-linked role is a Resource Access Management (RAM) role that can be assumed by the linked service. A service can assume the service-linked role to access other cloud resources. Service-linked roles help you better manage the operation permissions that are required by cloud services and prevent risks caused by accidental operations. For more information, see Service-linked roles.
Create the service-linked role AliyunServiceRoleForVpn
When you create a VPN gateway, the system automatically creates the service-linked role AliyunServiceRoleForVpn. A policy named AliyunServiceRolePolicyForVpn is attached to this role. This policy allows a VPN gateway to access other cloud resources. The policy contains the following permissions:
If the service-linked role AliyunServiceRoleForVpn already exists, the system does not create it again.

FAQ
Why am I unable to create the service-linked role AliyunServiceRoleForVpn by using a RAM user?
By default, an Alibaba Cloud account is authorized to create the service-linked role AliyunServiceRoleForVpn. If a RAM user wants to create the service-linked role, you must first use the Alibaba Cloud account to grant the required permissions to the RAM user.
You must create a custom policy and attach it to the RAM user. Then, the RAM user can create the service-linked role AliyunServiceRoleForVpn. The following code provides an example. For more information, see Create custom policies and Grant permissions to a RAM role.
