Key Lifetime
The number of seconds the key is valid. At the end of the lifetime,
the key is renegotiated.
The
is no way to change the renegotiation value. If the IKE Lifetime is
greater than 3600, the keys still get renegotiated every 3600
seconds.
Pre-Shared Key (PSK) - Specify an authenticating algorithm
and passcode used during authentication.
RSA Certificates - Select this option to use RSA certificates
for authentication purposes. See the CA Certificates and Self
certificates screens to create and import certificates into the
system.
MD5 - Enables the Message Digest 5 algorithm. No keys are
required to be manually provided.
SHA1 - Enables Secure Hash Algorithm. No keys are
required to be manually provided.
Pre-Shared Key
DES - Uses the DES encryption algorithm. No keys are
required to be manually provided.
3DES - Enables the 3DES encryption algorithm. No keys are
required to be manually provided.
AES 128-bit - Uses the Advanced Encryption Standard
algorithm with 128-bit. No keys are required to be manually
provided.
