Replacing Certificates of a VPN Gateway

Scenario

When certificates of a VPN gateway of the GM specification expire or become invalid, you need to replace the certificates.

After certificates of a VPN gateway are replaced, the customer gateway must use the corresponding new CA certificate to renegotiate with the VPN gateway. Otherwise, VPN connections will be disconnected.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. Click in the upper left corner of the page, and choose Networking > Virtual Private Network.
  4. In the navigation pane on the left, choose Virtual Private Network > Enterprise – VPN Gateways.
  5. Locate a VPN gateway of the GM specification, and choose More > View/Upload Certificate in the Operation column.
  6. Click Replace and set parameters as prompted.
    Table 1 describes the parameters for replacing certificates of a VPN gateway.
