Set Up a VPN Connection
A virtual private network (VPN) lets you use the Internet to securely access your network
when you are not home. This type of VPN access is called a client-to-gateway tunnel. The
computer is the client, and the modem router is the gateway. To use the VPN feature, you
must log in to the modem router and enable VPN, and you must install and run VPN client
software on the computer.
Note:
The modem router does not support iOS or Android VPN client software.
VPN uses DDNS or a static IP address to connect with your modem router.
To use a DDNS service, register for an account with a host name (sometimes called a
domain name). You use the host name to access your network. The modem router supports
these accounts: NETGEAR, No-IP, and Dyn. See
Set Up and Manage Dynamic DNS
on
page
176.
If your Internet service provider (ISP) assigned a static WAN IP address (such as 50.196.x.x
or 10.x.x.x) that never changes to your Internet account, the VPN can use that IP address to
connect to your home network.
Specify VPN Service in the Modem Router
You must specify the VPN service settings in the modem router before you can use a VPN
connection.
To specify the VPN service:
1.
Launch an Internet browser from a computer or WiFi device that is connected to the
network.

11.
Unzip the configuration files that you downloaded and copy them to the folder where the
VPN client is installed on your device.
For a client device with Windows 64-bit system, the VPN client is installed at
C:\Program files\OpenVPN\config\
by default.
12.
For a client device with Windows, modify the VPN interface name to
NETGEAR-VPN
:
a.
In Windows, select
Start > Control Panel > Network and Internet > Network
Connections
.
b.
In the local area connection list, find the local area connection with the device name
TAP-Windows Adapter
.
c.
Select the local area connection and change its name (not its device name) to
NETGEAR-VPN
.
If you do not change the VPN interface name, the VPN tunnel connection will fail.
Use a VPN Tunnel
After you set up the modem router to use VPN and install the OpenVPN application on your
computer, you can open a VPN tunnel from your computer to your modem router over the
Internet.
For the VPN tunnel to work, the local LAN IP address of the remote router must use a
different LAN IP scheme from that of the local LAN where your VPN client computer is
connected. If both networks use the same LAN IP scheme, when the VPN tunnel is
established, you cannot access your home router or your home network with the OpenVPN
software.
The default LAN IP address scheme for the modem router is 192.x.x.x. The most common IP
schemes are 192.x.x.x, 172.x.x.x, and 10.x.x.x. If you experience a conflict, change the IP
scheme either for your home network or for the network with the client VPN computer. For
information about changing these settings, see
Manage the Modem Router’s LAN IP
Address Settings
on page
208.
To open a VPN tunnel:
1.
Launch the OpenVPN application with administrator privileges.
