Step 2: Access OBS

Scenarios

This section describes how to access OBS using a VPN or Direct Connect connection.

Prerequisites

Your on-premises data center has been connected to your VPC using a VPN or Direct Connect connection.
  • The VPC subnet associated with the VPN gateway contains the OBS CIDR block.

    For details about how to create a VPN connection, see the Virtual Private Network User Guide.

  • The VPC subnet associated with the Direct Connect gateway contains the OBS CIDR block.

    For details about how to create a Direct Connect connection, see the Direct Connect User Guide.

Procedure

Configure an OBS route from the on-premises data center to the VPN or Direct Connect gateway.

The CIDR block of the VPC endpoint for accessing OBS is a public CIDR block. To access OBS over a VPN or Direct Connect connection, ensure that traffic from your on-premises data center to OBS is directed to the VPN gateway or Direct Connect gateway.

Configure a permanent route at your on-premises data center and specify the Direct Connect or VPN gateway as the next hop for accessing OBS. The following is the example command for configuring such a route:

route -p add Public IP address xxx.xxx.xxx.xxx
  • Public IP address indicates the address for accessing OBS.
  • xxx.xxx.xxx.xxx indicates the IP address of the Direct Connect or VPN gateway created at your on-premises data center.
  • The route command format varies depending on the OS. Use the route command format corresponding to the actual OS.
