Configuring IPSec Settings
Internet Protocol Security (IPSec or IPsec) is a protocol suite for encrypting data transported over a network, including Internet networks.
While SSL only encrypts data used on a specific application, such as a Web browser or an e-mail application, IPSec encrypts either whole
IP packets or the payloads of IP packets, offering a more versatile security system. The IPSec of the machine works in transport mode,
in which the payloads of IP packets are encrypted. With this feature, the machine can connect directly to a computer that is in the same
virtual private network (VPN). Check the system requirements and set the necessary configuration on the computer before you configure
the machine.
System Requirements
IPSec functional restrictions
IPSec supports communication to a unicast address (or a single device).
The machine cannot use both IPSec and DHCPv6 at the same time.
IPSec is unavailable in networks in which NAT or IP masquerade is implemented.
Using IPSec with IP address filter
IP address filter settings are applied before the IPSec policies. Specifying IP Addresses for Firewall Rules
IPSec that is supported by the machine conforms to RFC2401, RFC2402, RFC2406, and RFC4305.
