Dial-Up Networking for VPN
Microsoft Windows Dial-Up Networking software permits a remote standalone workstation to establish a VPN
tunnel to a PPTP ser ver 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 headquar ters, remotely. Netopia Routers also can ser ve as a PAC at the workstation's
site, making it unnecessar y 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, Windows NT, and
Windows XP. 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 inter vening 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 vir tual private
networking feature of your Netopia Router.

Installing Dial-Up Networking
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 Proper ties window appears.
3. Click the Windows Setup tab.
4. Double-click Communications.
