Ipsec Settings - Ricoh Aficio MP W5100 Operating Instructions Manual

5. Enhanced Network Security
Also, for further security, the SA can be periodically auto updated by applying a validity period (time limit)
for its settings. This machine only supports IKEv1 for encryption key auto exchange.
If you specify the encryption key manually, the SA settings must be shared and specified identically by both
parties. To preserve the security of your SA settings, we recommend that they are not exchanged over a
network.
Note that for both the manual and auto method of encryption key specification, multiple settings can be
configured in the SA.
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
5 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.
