Note

: Refer to

“Using Auto Policy to Configure VPN Tunnels” on page 8-36

to enable the IKE

keepalive capability on an existing VPN tunnel.

Step 2: Configuring the NETGEAR ProSafe VPN Client on the

Remote PC

This procedure describes how to configure the NETGEAR ProSafe VPN Client. We will assume

the PC running the client has a dynamically assigned IP address.

The PC must have the NETGEAR ProSafe VPN Client program installed that supports IPSec. 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.

1.

Install the NETGEAR ProSafe VPN Client on the remote PC and reboot.

•

You may need to insert your Windows CD to complete the installation.

•

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.

•

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.

•

The system should show the ProSafe icon (

) in the system tray after rebooting.

•

Double-click the system tray icon to open the Security Policy Editor.

2.

Add a new connection.

•

Run the NETGEAR ProSafe Security Policy Editor program and, using the

“VPN Tunnel

Configuration Worksheet” on page 8-8

, create a VPN Connection.

•

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 on LAN

A.

Note:

Before installing the NETGEAR ProSafe VPN Client software, be sure to turn off

any virus protection or firewall software you may be running on your PC.

Note:

In this example, the Connection Name used on the client side of the VPN tunnel is

toDG834

and it does not have to match the

RoadWarrior

Connection Name used on the

gateway side of the VPN tunnel (see

Figure 8-5

) 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.

•

Select the Connect using Secure Gateway Tunnel check box.

•

Select IP

Address in the ID Type menu below the check box.

•

Enter the public WAN IP Address of the DG834G in the field directly below the ID Type

menu. In this example,

22.23.24.25

would be used.

•

The resulting Connection Settings are shown in

Figure 8-10

.

3.

Configure the Security Policy in the NETGEAR ProSafe VPN Client software.

•

In the Network Security Policy list, expand the new connection by double clicking its

name or clicking on the “+” symbol. My Identity and Security Policy subheadings appear

below the connection name.

•

Click on the Security Policy subheading to show the Security Policy menu.
