This topic describes how to use a VPN gateway or an NAT gateway to access Apsara File Storage NAS from a local server.

By default, you can mount an Apsara File Storage NAS file system only on an ECS instance that resides in the same VPC as that of the file system. To access an Apsara File Storage NAS file system from a local server, you must use Express Connect, VPN Gateway, or NAT Gateway to connect your local IDC with the VPC where the file system resides.

After the network connection is established, you can mount the Apsara File Storage NAS file system on your local servers.
