You can encrypt the communication between your computer and the machine.
The communication is encrypted by IPSec. When IPSec is enabled, encryption is applied to
all the applications using the 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, it is invalid.
