Settings 1-4 and Default Setting
Using either the manual or auto exchange method, you can configure four separate sets of SA details
(such as different shared keys and IPsec algorithms). In the default settings of these sets, you can
include settings that the fields of sets 1 to 4 cannot contain.
When IPsec is enabled, set 1 has the highest priority and 4 has the lowest. You can use this priority
system to target IP addresses more securely. For example, set the broadest IP range at the lowest
priority (4), and then set specific IP addresses at a higher priority level (3 and higher). This way, when
IPsec transmission is enabled for a specific IP address, the higher level security settings will be applied.
