Ricoh SP C240SF, C242SF Description Authentication, Seconds IKE Diffie-Hellman

	Configuring the IPsec Settings
Item	Description
Authentication	Specify the authentication algorithm to be applied when [ESP] is selected
Algorithm for ESP	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.
Key Perfect Forward	Select whether to enable or disable PFS (Perfect Forward Secrecy).
