3.3.2.2.4 Configuring IP Security Proposal Table
The 'IP Security Proposals Table' page is used to configure Internet Key Exchange (IKE)
with up to four proposal settings. Each proposal defines an encryption algorithm, an
authentication algorithm, and a Diffie-Hellman group identifier. The same set of proposals
applies to both Main mode and Quick mode.
Note: You can also configure the IP Security Proposals table using the ini file table
parameter IPsecProposalTable (see ''Security Parameters'' on page 356).
¾ To configure IP Security Proposals:
1. Open the ‘IP Security Proposals Table’ page (Configuration tab > VoIP menu >
Security submenu > IPSec Proposal Table).
Figure 3-59: IP Security Proposals Table
In the figure above, four proposals are defined.
2. Select an Index, click Edit, and then modify the proposal as required.
3. Click Apply.
4. To save the changes to flash memory, see ''Saving Configuration'' on page 169.
To delete a p
roposal, select the relevant Index number, and then click Delete.
Table 3-13: IP Security Proposals Table Configuration Parameters
Parameter Name Description
Encryption Algorithm
[IPsecProposalTable_EncryptionAlgorithm]
Determines the encryption (privacy) algorithm.
 [0] NONE
 [1] DES CBC
 [2] 3DES CBC
 [3] AES (default)
Authentication Algorithm
[IPsecProposalTable_AuthenticationAlgorithm]
Determines the message authentication
(integrity) algorithm.
 [0] NONE
 [2] HMAC SHA1 96
 [4] HMAC MD5 96 (default)
Diffie Hellman Group
[IPsecProposalTable_DHGroup]
Determines the length of the key created by the
DH protocol for up to four proposals. For the ini
file parameter, X depicts the proposal number (0
to 3).
 [0] Group 1 (768 Bits) = DH-786-Bit
 [1] Group 2 (1024 Bits) (default) = DH-1024-
Bit
