To import a local certificate
Click Import.
The Import Certificates dialog is displayed.
Choose Import a CA certificate from a PKCS#7 (*.p7b) or DER (.der or .cer) encoded file. The Import Certificate dialog settings change.
When importing a CA certificate, the certificate name and password are not required; therefore, the Certificate Name and Certificate Management Password fields are disabled.
Reboot the firewall after importing a certificate to apply the changes.
