IKE Proposal index
A list of selected proposal indexes from the IKE proposal pool listed below. The selecting activity is
performed by selecting a proposal ID and clicking "add to" button in the bottom of the page. There are
only four indexes can be chosen from the proposal pool for the dedicated tunnel. Remove button beside
the index list can remove selected proposal index before.
Proposal name
It indicates which IKE proposal to be focused. First char of the name with 0x00 value stands for the IKE
proposal is not available.
• DH group
There are three groups can be selected: group 1 (MODP768), group 2 (MODP1024), group 5
(MODP1536).
Encryption algorithm
There are two algorithms can be selected: 3DES and DES.
Authentication algorithm
There are two algorithms can be selected: SHA1 and MD5.
Life time
The unit of life time is based on the value of Life Time Unit. If the value of unit is second, the value of
life time represents the life time of dedicated VPN tunnel between both end gateways. Its value ranges
from 300 seconds to 172,800 seconds. If the value of unit is KB, the value of life time represents the
maximum allowable amount of transmitted packets through the dedicated VPN tunnel between both end
gateways. Its value ranges from 20,480 KBs to 2,147,483,647 KBs.
Life time unit
There are two units can be selected: second and KB.
Proposal ID
The identifier of IKE proposal can be chosen for adding corresponding proposal to the dedicated tunnel.
There are total ten proposals can be set in the proposal pool. At most only four proposals from the pool
can be applied to the dedicated tunnel as shown in the proposal index list.
Function of Buttons
Add to button: Click it to add the chosen proposal indicated by proposal ID to IKE Proposal index list.
The proposals in the index list will be used in phase 1 of IKE negotiation for getting the IKSAMP SA of
dedicated tunnel.
