Understanding IKE VPN3000

Hi all together,

I still have a problem understanding the IKE settings in the VPN 3000 Concentrator. Can someone tell me for what purpose the IKE Parameters under Configuration | Policy Management | Traffic Manangement | SAs are good for?

In my understanding the order of establishing a tunnel is:

1. Client sends IKE proposals to the concentrator. The concentrator looks in the active proposals (Configuration | Tunneling and Security | IPSec | IKE Proposals) and uses the first matching proposal to handle IKE Phase 1

2. The user group's IPSec SA (Configuration | User Management | groups | IPSec tab | IPSec SA) is used for IKE Phase 2. These IPSec Parameters are configured in the section "IPSec Paramters" in Configuration | Policy Management | Traffic Management | SAs.

I don't understand for what the IKE parameters are good for. Perhaps someone can tell me.

Thanks a lot for your help.

Markus

Re: Understanding IKE VPN3000

IKE provides these benefits:

1.Eliminates the need to manually specify all the IPSec security parameters in the crypto maps at both peers.

2.Allows you to specify a lifetime for the IPSec security association.

3.Allows encryption keys to change during IPSec sessions.

4.,Allows IPSec to provide anti-replay services.

5.Permits CA support for a manageable, scalable IPSec implementation.

6.Allows dynamic authentication of peers.
