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 must 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.

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. Select
Secure
.
ID Type. Select
IP Subnet
.
Subnet. In this example, type
192.168.3.1
as the network address of the N300
wireless modem router.
Mask. Enter
255.255.255.0
as the LAN subnet mask of the N300 wireless modem
router.
Protocol. Select
All
to allow all traffic through the VPN tunnel.

Select the
Connect using Secure Gateway Tunnel
check box.
