IKE Table Configuration Parameters
Parameter Name
Description
Shared Key
[IKEPolicySharedKey]
Determines the pre-shared key (in textual format).
Both peers must register the same pre-shared key for the authentication
process to succeed.
The pre-shared key forms the basis of IPSec security and should
therefore be handled cautiously (in the same way as sensitive
passwords). It is not recommended to use the same pre-shared
key for several connections.
Since the ini file is in plain text format, loading it to the gateway
over a secure network connection is recommended, preferably
over a direct crossed-cable connection from a management PC.
For added confidentiality, use the encoded ini file option
(described in
Secured ini File
).
After it is configured, the value of the pre-shared key cannot be
obtained using Web, ini file or SNMP (see
IPSec and IKE
Configuration Table’s Confidentiality
).
