Installation Overview
To encrypt communications using IPSec, configure the machine and your computer as
follows:
Configuration on the Machine
When [IKE Authentication Method] is set to [Authenticate by Digital Signature], configure
a certificate on the machine. No certificate is registered on the machine by factory default.
After importing a certificate, configure IPSec.
Configure the following setting to set up a certificate on the machine.
• Configuring certificates by Dell Printer Configuration Web Tool
- Enable HTTPS, and then import a certificate issued by another CA to the machine.
Note • If a certificate to be imported as an IPSec certificate contains V3 extension "KeyUsage",
"digitalSignature" bit must be asserted.
Configuration on the Computer
Configure the following settings to encrypt communications between a computer and the
machine.
• Create an IP security policy
• Assign the IP security policy
Step1 Import and Configuration of a Certificate
The following describes configuration procedures to set up a certificate with Dell Printer
Configuration Web Tool.
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.
Note • You cannot use a self-signed certificate created with Dell Printer Configuration Web Tool for IPSec.
For details on how to configure the encryption settings for HTTP communication, refer to
"Configuration of HTTP Communications Encryption" (P.466).
