Replacing the Certificate of a Customer Gateway

Scenario

When the CA certificate of a customer gateway that uses SM series cryptographic algorithms expires or becomes invalid, you need to replace the CA certificate.

After the CA certificate is replaced, the customer gateway needs to use the SM certificate issued based on the 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 – Customer Gateways.
  5. On the Customer Gateways page, click the name of the target customer gateway.
  6. In the CA Certificate area, click Replace.
  7. Set parameters as prompted.

    Table 1 describes the parameters for replacing the CA certificate of a customer gateway.
