Select a Remote Gateway to associate with the VPN tunnel.
A remote gateway can be either a gateway to another network or an individual client
on the Internet. Remote gateways are added as part of the phase 1 configuration. For
details, see
"Adding a phase 1 configuration for an AutoIKE VPN" on page
Choose either a single DIALUP remote gateway, or up to three STATIC remote
gateways. Multiple STATIC remote gateways are necessary if you are configuring
IPSec redundancy. For information about IPSec redundancy, see

Configure the P2 Proposal.
Select up to three encryption and authentication algorithm combinations to propose
for phase 2.
The VPN peers must use the same P2 proposal settings.
6
Optionally, enable Replay Detection.
Replay detection protects the VPN tunnel from replay attacks.
Note: Do not select replay detection if you have also selected Null Authentication for the P2
Proposal.
7
Optionally, enable Perfect Forward Secrecy (PFS).
PFS improves security by forcing a new Diffie-Hellman exchange whenever keylife
expires.
8
Select the DH Group(s).
The VPN peers must use the same DH Group settings.

Enter the Keylife.
The keylife causes the phase 2 key to expire after a specified amount of time, after a
specified number of kbytes of data have been processed by the VPN tunnel, or both. If
you select both, the key does not expire until both the time has passed and the
number of kbytes have been processed.
When the key expires, a new key is generated without interrupting service. P2
proposal keylife can be from 120 to 172800 seconds or from 5120 to 99999 kbytes.
Optionally, enable Autokey Keep Alive.
Enable Autokey Keep Alive to keep the VPN tunnel running even if no data is being
processed.

Optionally, select a concentrator.
Select a concentrator if you want the tunnel to be part of a hub and spoke VPN
configuration. If you use the procedure,
add the tunnel to a concentrator, the next time you open the tunnel, the Concentrator
field displays the name of the concentrator to which you have added the tunnel.
Select OK to save the AutoIKE key VPN tunnel.
