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 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 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.
