If the VPN Policy is a "Manual" policy, then the Manual Policy Parameters defined in the VPN policy are accessed and the first matching IKE policy is used to start negotiations with the remote VPN gateway. • If negotiations fail, the next matching IKE policy is used. • If none of the matching IKE policies are acceptable to the remote VPN gateway, then a VPN tunnel cannot be established. 3. An IKE session is established, using the SA (Security Association) parameters specified in a matching IKE Policy: • Keys and other parameters are exchanged. • An IPsec SA (Security Association) is established, using the parameters in the VPN policy. The VPN tunnel is then available for data transfer. The IKE Policies Tab Page When you use the VPN Wizard to set up a VPN tunnel, an IKE policy is established and populated in the List of IKE Policies and is given the same name as the new VPN connection name. You can also edit exiting policies or add new IKE policies directly on the List of IKE Policies. Each policy contains the following data: • Name. Uniquely identifies each IKE policy. The name is chosen by you and used for managing your policies; it is not supplied to the remote VPN endpoint. • Mode. Two modes are available: either Main or Aggressive. - Main Mode is slower but more secure. - Aggressive mode is faster but less secure. (If specifying either a FQDN or a User FQDN name as the Local ID/Remote ID, aggressive mode is automatically selected.) • Local ID. The IKE/ISAKMP identify of this device. (The remote VPN must have this value as their Remote ID.) • Remote ID. The IKE/ISAKMP identify of the remote VPN gateway. (The remote VPN must have this value as its Local ID.) • Encr. Encryption algorithm used for the IKE SA. The default setting using the VPN Wizard is 3DES. (This setting must match the Remote VPN.) • Auth. Authentication Algorithm used for the IKE SA. The default setting using the VPN Wizard is SHA1. (This setting must match the Remote VPN.) Virtual Private Networking Using IPsec 1.1 November, 2009 5-15

2.
If the VPN Policy is a “Manual” policy, then the
Manual Policy Parameters
defined in the
VPN policy are accessed and the first matching IKE policy is used to start negotiations with
the remote VPN gateway.
•
If negotiations fail, the next matching IKE policy is used.
•
If none of the matching IKE policies are acceptable to the remote VPN gateway, then a
VPN tunnel cannot be established.
3.
An IKE session is established, using the SA (Security Association) parameters specified in a
matching IKE Policy:
•
Keys and other parameters are exchanged.
•
An IPsec SA (Security Association) is established, using the parameters in the VPN
policy.
The VPN tunnel is then available for data transfer.
The IKE Policies Tab Page
When you use the VPN Wizard to set up a VPN tunnel, an IKE policy is established and populated
in the List of IKE Policies and is given the same name as the new VPN connection name. You can
also edit exiting policies or add new IKE policies directly on the List of IKE Policies. Each policy
contains the following data:
•
Name
. Uniquely identifies each IKE policy. The name is chosen by you and used for
managing your policies; it is not supplied to the remote VPN endpoint.
•
Mode
. Two modes are available: either Main or Aggressive.
–
Main Mode is slower but more secure.
–
Aggressive mode is faster but less secure. (If specifying either a FQDN or a User FQDN
name as the Local ID/Remote ID, aggressive mode is automatically selected.)
•
Local ID
. The IKE/ISAKMP identify of this device. (The remote VPN must have this value as
their Remote ID.)
•
Remote ID
. The IKE/ISAKMP identify of the remote VPN gateway. (The remote VPN must
have this value as its Local ID.)
•
Encr
. Encryption algorithm used for the IKE SA. The default setting using the VPN Wizard is
3DES. (This setting must match the Remote VPN.)
•
Auth
. Authentication Algorithm used for the IKE SA. The default setting using the VPN
Wizard is SHA1. (This setting must match the Remote VPN.)
