N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 Step 2: Configure Gateway B (VPN Router at Regional Office) This procedure assumes that the PC running the client has a dynamically assigned IP address. The PC has to 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 (www.netgear.com) for information about how to purchase the NETGEAR ProSafe VPN Client. Note: Before installing the software, be sure to turn off any virus protection or firewall software you might be running on your PC.  To configure a VPN tunnel: 1. Install the NETGEAR ProSafe VPN Client on the remote PC, and then reboot. a. You might 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 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. c. 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. d. The system should show the ProSafe icon ( ) in the system tray after you reboot. 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. b. From the Edit menu of the Security Policy Editor, select Add > Connection. A New Connection listing appears in the list of policies. c. Rename the new connection to match the connection name you entered in the VPN settings of Gateway A. Choose connection names that make sense to the people using and administrating the VPN. NETGEAR VPN Configuration 169
