Setting Up the Client-to-Gateway VPN Configuration (Telecommuter Example)

Setting up a VPN between a remote PC running the NETGEAR ProSafe VPN Client and a network gateway involves the following two steps:

• Step 1: Configuring the Client-to-Gateway VPN Tunnel on the VPN Router at the Employer’s Main Office.

• Step 2: Configuring the NETGEAR ProSafe VPN Client on the Remote PC at the Telecommuter’s Home Office configures the NETGEAR ProSafe VPN Client endpoint.

Step 1: Configuring the Client-to-Gateway VPN Tunnel on the VPN Router at the Employer’s Main Office

Step 2: Configuring the NETGEAR ProSafe VPN Client on the Remote PC at the Telecommuter’s Home Office

This procedure describes how to configure the 54 Mbps ADSL Modem Wireless Router Model DG834G. We will assume the PC running the client has a dynamically assigned IP address.

The PC must have a VPN client program installed that supports IPSec (in this case study, the NETGEAR VPN ProSafe Client is used). Go to the NETGEAR website (http://www.netgear.com) and select VPN01L_VPN05L in the Product Quick Find drop-down menu for information on how to purchase the NETGEAR ProSafe VPN Client.

Note: Before installing the 54 Mbps ADSL Modem Wireless Router Model DG834G software, be sure to turn off any virus protection or firewall software you may be running on your PC.

1. Install the NETGEA ProSafe VPN Client on the remote PC and reboot. a. You may need to insert your Windows CD to complete the installation. b. If you do not have a modem or dial-up adapter installed in your PC, you may see the warning message stating “The NETGEAR ProSafe VPN Component requires at least one dial-up adapter be installed.” You can disregard this message. c. Install the IPSec Component. You may have the option to install either the VPN Adapter or the IPSec Component or both. The VPN Adapter is not necessary. d. The system should show the ProSafe icon (S) in the system tray after rebooting. e. Double-click the system tray icon to open the Security Policy Editor.
2. Add a new connection. a. Run the NETGEAR ProSafe Security Policy Editor program and create a VPN Connection.

NETGEAR VPN Configuration

b. From the Edit menu of the Security Policy Editor, click Add, then Connection. A New Connection listing appears in the list of policies. Rename the New Connection so that it matches the Connection Name you entered in the VPN Settings of the DG834G v3 on Gateway A.

Note: In this example, the Connection Name used on the client side of the VPN tunnel is toDG834G and it does not have to match the VPN_client Connection Name used on the gateway side of the VPN tunnel (see Figure B-16) because Connection Names are arbitrary to how the VPN tunnel functions.

Tip: Choose Connection Names that make sense to the people using and administrating the VPN.
