Adding a CA certificate to an edge gateway enables trust verification of SSL certificates that are presented to the edge gateway for authentication, typically the client certificates used in VPN connections to the edge gateway.

About this task

You usually add your company's or organization's root certificate as a CA certificate. A typical use is for SSL VPN, where you want to authenticate VPN clients using certificates. Client certificates could be distributed to the VPN clients and when the VPN clients connect, their client certificates would be validated against the CA certificate.


When adding a CA certificate, you typically configure a relevant CRL (Certificate Revocation List). The CRL protects against clients that present revoked certificates. For the steps on adding a CRL to the edge gateway, see Add a Certificate Revocation List to an Edge Gateway.


Verify you have the CA certificate data in PEM format. In the user interface, you can either paste in the CA certificate's PEM data or browse to a file that contains the data and is available in your network from your local system.

To use the vCloud Director tenant portal to work with an edge gateway's settings, the edge gateway must be converted to an advanced edge gateway. You can do this on the edge gateway in the vCloud Director Web console or from the tenant portal. For details on performing this step from the tenant portal, see Convert an Edge Gateway to an Advanced Edge Gateway.


  1. Launch Edge Gateway Services by completing the following steps.
    1. Click Network > Edge Gateway.
    2. Select the edge gateway to edit, and click Configure Services.

      The tenant portal opens Edge Gateway Services.

  2. Click the Certificates tab.
  3. Click + CA CERTIFICATE.
  4. Provide the CA certificate's data using one of these methods:
    • If the data is in a PEM file on a system you can navigate to, click the import button to browse to the file and select it.

    • If you can copy and paste the PEM data, paste it into the CA Certificate (PEM format) field. Include the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- lines.

  5. (Optional) Type an optional description.
  6. Click Keep.


The CA certificate with type CA Certificate appears in the on-screen list. This CA certificate is now available for you to specify when you configure the edge gateway's VPN-related settings.
