on page

information about how to enable the IKE keep-alive capability on an existing

Step 2: Configure the NETGEAR ProSafe VPN Client
This section describes how to configure the NETGEAR ProSafe VPN Client on a remote PC.
These instructions assume that the PC running the client has a dynamically assigned IP
address.
The PC has to have the NETGEAR ProSafe VPN Client program installed that supports
IPSec. Go to the NETGEAR website (
) for information about how to
purchase the NETGEAR ProSafe VPN Client.
Note:
Before installing the NETGEAR ProSafe VPN Client software, be
sure to turn off any virus protection or firewall software you might be
running on your PC. You might need to insert your Windows CD to
complete the installation.
1.
Install the NETGEAR ProSafe VPN Client on the remote PC, and then reboot.
a.
Install the IPSec component. You might have the option to install either the VPN
adapter or the IPSec component or both. The VPN adapter is not necessary.
If you do not have a modem or dial-up adapter installed in your PC, you might see the
warning message stating “The NETGEAR ProSafe VPN Component requires at least
one dial-up adapter be installed.” You can disregard this message.
b.
Reboot the remote PC.
The ProSafe icon (
) is in the system tray.
c.
Double-click the ProSafe icon to open the Security Policy Editor.
2.
Add a new connection.
a.
Run the NETGEAR ProSafe Security Policy Editor program, and, using the
Table

Add
, and then click
Connection

A New Connection listing appears in the list of policies.
c.
Rename the new connection so that it matches the Connection Name field in the
VPN Settings screen of the modem router on LAN A. Choose connection names that
make sense to the people using and administering the VPN.
Note:
In this example, the connection name used on the client side of the
VPN tunnel is toGW_A, and it does not have to match the
RoadWarrior connection name used on the gateway side of the VPN
tunnel because connection names are irrelevant to how the VPN
tunnel functions.
d.
Enter the following settings:
•
Connection Security:
Secure
.
•
ID Type:
IP Subnet
.
•
Subnet.: In this example, type
192.168.3.1
as the network address of the modem
router.
•
Mask: Enter
255.255.255.0
as the LAN subnet mask of the modem router.
•
Protocol: Select
All
to allow all traffic through the VPN tunnel.
e.
Select
Connect using
and then select the
Secure Gateway Tunnel
check box.
f.
In the ID Type drop-down list, select
IP Address
.
g.
I the field directly below the ID Type drop-down list, enter the public WAN IP address
of the modem router. In this example, 22.23.24.25 is used.
The resulting connection settings are shown in
