ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual About the IKE Policy Table 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: • Policy Name. Uniquely identifies each IKE policy. The name is chosen by you and used for the purpose of managing your policies; it is not supplied to the remote VPN Server. • Direction / Type. • Both • Initiator • Responder • Exchange Mode. Two modes are available: either Main or Aggressive. Main Mode negotiates the tunnel with higher security, but is slower whereas Aggressive Mode establishes a faster connection but with lowered security. Note: If either the Local or Remote identifier type (defined below) is not an IP address, then negotiation is only possible in Aggressive Mode. If FQDN, User FQDN or DER ASN1 DN is selected, the router will disable Main Mode and set the default to Aggressive Mode. • Mode Config Record Specify whether this IKE policy uses a Mode Config Record (Mode Config Records can be defined on the Mode Config page under the VPN menu). Select the Yes radio button if you would like IP addresses to be assigned to remote VPN Clients. Since Mode Config works only in Aggressive Mode, enabling this will set the tunnel exchange mode to Aggressive Mode and disable Main Mode. Mode Config also requires that both the local and remote ends be defined by their Internet Names (FQDN) only. • 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.) • IKE SA Parameters - Encryption Algorithm. This algorithm is used for the IKE SA. The default setting using the VPN Wizard is 3DES. (This setting must match the Remote VPN.) - Authentication Algorithm. This algorithm is 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 v1.0, October 2008 6-13
