You can encrypt communication between your computer and the machine.
The communication is encrypted by IPSec. When IPSec is enabled, encryption is applied for
all the applications by using IP protocols.
You can specify up to 50 hosts by their IP addresses. When a host that is not registered tries
to access the machine, it is rejected. When you try to access a host that is not registered, the
attempt is invalid.
Be sure to configure the machine in advance, before configuring your computer.
You must have a pre-shared key readied in advance.
Setting This Machine
To enable IPSec, you must set this machine by using the Web page in advance.
• If IPsec is set to this machine and the host, IPSec communication is established. If IPSec is not set to the host, IPSec
communication is not established.
• Do not forget to take notes of the values specified in this procedure. These values are necessary when setting IPSec
on a computer.
