Configuring an IKE Phase 1 Proposal—Quick Configuration

You can use J-Web Quick Configuration to quickly configure an IKE Phase 1 proposal.

Figure 61 shows the quick configuration page where can you select an existing Phase 1 proposal, or click Add to create a new one.

IKE Phase 1 Proposal Configuration Options

To configure an IKE proposal with Quick Configuration:

  1. Select Configuration > Quick Configuration > VPN > IKE.
  2. Select the Phase 1 Proposal tab if it is not selected.
  3. To use an existing proposal, select it from among those listed and click one of the following buttons:
  4. To configure a new IKE policy, click Add.

    Figure 62 shows the quick configuration page where you create a new IKE proposal.

  5. Fill in the options as described in Table 139.
  6. Click one of the following buttons:

Table 139: Phase 1 Proposal Configuration Options




IKE Proposal (Phase 1)


The name of the proposal.

Enter a name.

Authentication algorithm

The Authentication Header (AH) algorithm the device uses to verify the authenticity and integrity of a packet. Supported algorithms include the following:

  • md5—Produces a 128-bit digest.
  • sha1—Produces a 160-bit digest.
  • sha-256—Produces a 256-bit digest.

Select an algorithm.

Authentication method

The method the device uses to authenticate the source of Internet Key Exchange (IKE) messages. Options include:

  • pre-shared-keys—Key for encryption and decryption that both participants must have before beginning tunnel negotiations.
  • rsa-key—Kinds of digital signatures, which are certificates that confirm the identity of the certificate holder.

Select an authentication method.


Easy identification of the proposal.

Enter brief description of the IKE proposal.

Dh group

The Diffie-Hellman exchange allows participants to produce a shared secret value over an unsecured medium without actually transmitting the value across the connection.

Select a group. If you configure multiple (up to four) proposals for Phase 1 negotiations, use the same Diffie-Hellman group in all proposals.

Encryption altorithm

Supported Internet Key Exchange (IKE) proposals include the following:

  • 3des-cbc—3DES-CBC encryption algorithm.
  • aes-128-cbc—AES-CBC 128-bit encryption algorithm.
  • aes-192-cbc—AES-CBC 192-bit encryption algorithm.
  • aes-256-cbc—AES-CBC 256-bit encryption algorithm.
  • des-cbc—DES-CBC encryption algorithm.

Select an encryption algorithm.

Lifetime seconds

The lifetime (in seconds) of an IKE security association (SA). When the SA expires, it is replaced by a new SA and security parameter index (SPI) or terminated.

Select a lifetime for the IKE SA.

Default: 3,600 seconds.

Range: 180 through 86,400 seconds.
