When encrypting IPP communications (Internet printing) and adding a printer from Add Printer, enter an address beginning with "https" instead of "http" as the URL of the printer. Configuration of Encryption using IPSec This section describes how to encrypt communications using IPSec. Step 1 Import and Configuration of a Certificate The following describes configuration procedures to set up a certificate with Dell Printer Configuration Web Tool. When IKE Authentication Method is set to Digital Signature, configure a certificate on the machine. No certificate is registered on the machine by factory default. To configure a certificate using Dell Printer Configuration Web Tool, configure the encryption settings for HTTP communications, and then import a certificate issued by another CA to use it for the IPSec certificate.
