SA (Security Association)
A Security Association (SA) is the establishment of shared security attributes
between two network entities to support secure communication.
An SA may include attributes such as:
cryptographic algorithm and mode; traffic encryption key; and parameters for the
network data to be passed over the connection.
Establishment of an SA is described in RFC 2408, the Internet Security
Association and Key Management Protocol.
This page allows you to configure SA.
IKE (Phase 1) Proposal
Exchange
Select Main Mode or Aggressive Mode for IKE Phase 1 negotiation.
• Main Mode: Select this option to configure the standard negotiation parameters
for IKE Phase 1 of the VPN Tunnel. (Recommended Setting)
• Aggressive Mode: Select this option to configure IKE Phase 1 of the VPN Tunnel
to carry out negotiation in a shorter amount of time. (Not Recommended - Less
Secure)
DH Group
Select a DH Group from the drop-down menu (Group 1, Group2, Group5 and
Group14). As the DH Group number increases, the higher the level of encryption
implemented for IKE Phase 1.
Encryption
The WLR-6001 supports DES, 3DES, AES128, AES192, AES256 encryption
methods for traffic through the VPN.
Authentication
The WLR-6001 supports SHA1, MD5 methods for authentication.
Life Time Enter the number of seconds for the IKE Lifetime. The period of time to
pass before establishing a new IKE security association (SA) with the remote
endpoint. The default value is 28800.
