    Configure an OCSP Responder

    To use Online Certificate Status Protocol (OCSP) for verifying the revocation status of certificates, you must configure the firewall to access an OCSP responder (server). The entity that manages the OCSP responder can be a third-party certificate authority (CA). If your enterprise has its own public key infrastructure (PKI), you can use external OCSP responders or you can configure the firewall itself as an OCSP responder. For details on OCSP, see Certificate Revocation.
    1. Define an external OCSP responder or configure the firewall itself as an OCSP responder.
      1. Select DeviceCertificate ManagementOCSP Responder and click Add.
      2. Enter a Name to identify the responder (up to 31 characters). The name is case-sensitive. It must be unique and use only letters, numbers, spaces, hyphens, and underscores.
      3. If the firewall has more than one virtual system (vsys), select a Location (vsys or Shared) for the certificate.
      4. In the Host Name field, enter the host name (recommended) or IP address of the OCSP responder. You can enter an IPv4 or IPv6 address. From this value, PAN-OS automatically derives a URL and adds it to the certificate being verified.
        If you configure the firewall itself as an OCSP responder, the host name must resolve to an IP address in the interface that the firewall uses for OCSP services.
      5. Click OK.
    2. If you want the firewall to use the management interface for the OCSP responder interface, enable OCSP communication on the firewall. Otherwise, continue to the next step to configure an alternate interface.
      1. Select DeviceSetupManagement.
      2. In the Management Interface Settings section, edit to select the HTTP OCSP check box, then click OK.
    3. To use an alternate interface as the OCSP responder interface, add an Interface Management Profile to the interface used for OCSP services.
      1. Select NetworkNetwork ProfilesInterface Mgmt.
      2. Click Add to create a new profile or click the name of an existing profile.
      3. Select the HTTP OCSP check box and click OK.
      4. Select NetworkInterfaces and click the name of the interface that the firewall will use for OCSP services. The OCSP Host Name specified in Step 1 must resolve to an IP address in this interface.
      5. Select AdvancedOther info and select the Interface Management Profile you configured.
      6. Click OK and Commit.
