VPN 3000 Concentrator Series User Guide

Active Proposals

The field shows the names of IKE proposals that have been configured, activated, and prioritized. As an

IPSec responder, the VPN Concentrator checks these proposals in priority order, to see if it can find one

that agrees with parameters in the initiator’s proposed SA.

Activating a proposal also makes it available for use wherever the Manager displays an

IKE Proposal list,

and the first active proposal appears as the default selection.

Inactive Proposals

The field shows the names of IKE proposals that have been configured but are inactive. New proposals

appear in this list when you first configure and add them. The VPN Concentrator does not use these

proposals in any IPSec negotiations, nor do they appear in

IKE Proposal lists.

Note: To configure L2TP over IPSec, you must activate

IKE-3DES-MD5-RSA. Also see the Configuration | User

Management

screens.

<< Activate

To activate an inactive IKE proposal, select it from the Inactive Proposals list and click this button. The

Manager moves the proposal to the

Active Proposals list and refreshes the screen.

>> Deactivate

To deactivate an active IKE proposal, select it from the Active Proposals list and click this button. If the

active proposal is configured on a Security Association, the Manager displays an error message; and you

must remove it from the SA before you can deactivate it. Otherwise, the Manager moves the proposal to

the

Inactive Proposals list and refreshes the screen.

Move Up / Move Down

To change the priority order of an active IKE proposal, select it from the Active Proposals list and click

Move Up or Move Down. The Manager refreshes the screen and shows the reordered Active Proposals list.

These actions move the proposal up or down one position.

Add

To configure and add a new IKE proposal to the list of Inactive Proposals, click this button. See
