The Global VPN Client support two IPSec Keying modes: IKE using Preshared Secret and IKE using 3rd Party Certificates. Preshared Secret is the most common form of the IPSec Keying modes. If your VPN connection policy uses 3rd party certificates, you use the Certificate Manager to configure the Global VPN Client to use digital certificates.

A Pre-Shared Key (also called a Shared Secret) is a predefined field that the two endpoints of a VPN tunnel use to set up an IKE (Internet Key Exchange) Security Association. This field can be any combination of Alphanumeric characters with a minimum length of 4 characters and a maximum of 128 characters. Your Pre-Shared Key is typically configured as part of your Global VPN Client provisioning. If it is not, you are prompted to enter it before you log on to the remote network.

Accessing Redundant VPN Gateways

The Global VPN Client supports redundant VPN gateways by manually adding the peer in the Peers page of the VPN connection Properties dialog box. See “Peers” on page 26 for more information. The Global VPN Client version 2.1.0.0 (or higher) adds automatic support for redundant VPN gateways if the IPSec gateway’s domain name resolves to multiple IP address. For example, if gateway.yourcompany.com resolves to 67.115.118.7, 67.115.118.8 and 67.115.118.9, the Global VPN Client cycles through these resolved IP addresses until it finds a gateway that responds, allowing multiple IP addresses to be used as failover gateways. If all the resolved IP addresses fail to respond, Global VPN Client switches to the next peer, if another peer is specified in the Peers page of the VPN connection Properties dialog box. See “Peers” on page 26 for more information.

Note! When configuring redundant VPN gateways, the Group VPN policy attributes (such as pre-shared keys and the attributes on the Peer Information window) must be the same for every gateway.

Enabling a VPN Connection

Enabling a VPN connection with the SonicWALL Global VPN Client is a transparent two phase process. Phase 1 enables the connection, which completes the ISAKMP (Internet Security Association and Key Management Protocol) negotiation. Phase 2 is IKE (Internet Key Exchange) negotiation, which establishes the VPN connection for sending and receiving data.

When you enable a VPN connection policy, the following information is displayed in the Status column of the SonicWALL Global VPN Client window:

1.Disabled changes to Connecting.

2.Connecting changes to Authenticating when the Enter Username/Password dialog box is displayed.

3.Authenticating changes to Connecting when the user enters the username and password.

4.Connecting changes to Provisioning.

5.Provisioning changes to Connected once the VPN connection is fully established. A green checkmark is displayed on the VPN connection policy icon.

Once the VPN connection is established, a pop-up notification is displayed from the Global VPN Client system tray icon. It displays the Connection Name, Connected to IP address and the Virtual IP Address.

If an error occurs during the VPN connection, Error appears in the Status column and an error mark (red x) appears on the VPN connection policy icon. A VPN policy that doesn’t successfully complete all phase 2 connections displays a yellow warning symbol on the policy icon.

Note! If the Global VPN Client doesn’t establish the VPN connection, you can use the Log Viewer to view the error messages to troubleshoot the problem. See “Understanding the Global VPN Client Log” on page 31 for more information.
