Microsoft Windows Dial-Up Networking software permits a remote stand-alone workstation to establish a VPN

tunnel to a PPTP server such as a Netopia Router located at a central site. Dial-Up Networking also allows a

mobile user who may not be connected to a PAC to dial into an intermediate ISP and establish a VPN tunnel to,

for example, a corporate headquarters, remotely. Netopia Routers also can serve as a PAC at the workstation's

site, making it unnecessary for the standalone workstation to initiate the tunnel. In such a case, the Dial-Up

Networking software is not required, since the Netopia Router initiates the tunnel.

This section is provided for users who may require the VPN client software for Dial-Up Networking in order to

connect to an ISP who provides a PPTP account.

Microsoft Windows Dial-Up Networking (DUN) is the means by which you can initiate a VPN tunnel between your

individual remote client workstation and a private network such as your corporate LAN via the Internet. DUN is a

software adapter that allows you to establish a tunnel.

DUN is a free add-on available for Windows 95, and comes standard with Windows 98 and Windows NT. The

VPN tunnel behaves as a private network connection, unrelated to other trafﬁc on the network. Once you have

installed Dial-Up Networking, you will be able to connect to your remote site as if you had a direct private

connection, regardless of the intervening network(s) through which your data passes. You may need to install

the Dial-Up Networking feature of Windows 95, 98, or 2000 to take advantage of the virtual private networking

feature of your Netopia router.

Note: For the latest information and tech notes on Dial-Up Networking and VPNs be sure to visit the Netopia

Check to see if Dial-Up Networking is already installed on your PC. Open your My Computer (or whatever you

have named it) icon on your desktop. If there is a folder named Dial-Up Networking, you don’t have to install it.

If there is no such folder, you must install it from your system disks or CDROM. Do the following:

1. From the Start menu, select Settings and then Control Panel.

2. In the Control Panel window, double-click the Add/Remove Programs icon.

The Add/Remove Programs Properties window appears.

3. Click the Windows Setup tab.

4. Double-click Communications.
