Configuring the IPsec Settings Item Authentication Algorithm for ESP Life Time Key Perfect Forward Secrecy Description Specify the authentication algorithm to be applied when [ESP] is selected for [Security Protocol] from the following: [MD5], [SHA1] Specify the life time of the IPsec SA (Security Association) as a time period or data volume. The SA will expire when the time period you specify elapses or the volume of data you specify reaches the volume carried. If you specify both a time period and a data volume, the SA will expire as soon as either is reached, and a new SA will then be obtained by negotiation. To specify the life time of the SA as a time period, enter a number of seconds. To specify the life time of the SA as a data volume, enter a number of KBs.

Description
Authentication
Algorithm for ESP
Specify the authentication algorithm to be applied when [ESP] is selected
for [Security Protocol] from the following:
[MD5], [SHA1]
Life Time
Specify the life time of the IPsec SA (Security Association) as a time period
or data volume. The SA will expire when the time period you specify
elapses or the volume of data you specify reaches the volume carried.
If you specify both a time period and a data volume, the SA will expire as
soon as either is reached, and a new SA will then be obtained by
negotiation.
To specify the life time of the SA as a time period, enter a number of
seconds.
To specify the life time of the SA as a data volume, enter a number of KBs.
