This article describes how to set up a private network connection over the
Internet using the Point-to-Point Tunneling protocol (PPTP).
You can establish secure, multiple-protocol Virtual Private Network (VPN)
connections over public data networks such as the Internet using PPTP. By
dialing into your Internet service provider's point of presence (POP), you
can access your corporate networks and programs without dialing directly
into the company's network. PPTP connects directly to the target server by
creating a virtual network for each remote client. A Windows NT 4.0 Server
administrator can monitor and manage such a virtual network just like any
other remote access port.
To use PPTP to connect to a server securely across the Internet, you must
first install the PPTP protocol. To do so, follow these steps:
- In Control Panel, double-click Network, and then click the Protocols
- Add Point To Point Tunneling Protocol.
- After the protocol is loaded, Remote Access Services Setup is invoked. You must add at least one VPN port as a port in RAS Setup. You may need to configure the newly created VPN adapter to "Dial out and receive calls." The default setting is "Receive calls only."
- Specify the protocols to run for the VPN port. You can install up to
256 VPN ports. Each VPN can be connected to a network.
- If you have Service Pack 3 or later installed, reapply the service pack,
and then restart the computer.
To make a PPTP connection to a target server over the Internet, follow
- In Dial-Up Networking, make a new phone book entry for the target
server. For the phone number, specify the IP address or host name of
the server. Make sure to specify the VPN port you want to use.
NOTE: After you have a phone book entry set up, you can check and
modify phone book settings by clicking More, and then clicking Edit
Entry And Modem Properties. In the Phone Book Entry dialog box, verify
that the Dial Using box specifies a VPN port. Click the Server tab, and
verify that a protocol that the target server uses is selected. You can
specify the security you want on the Security tab.
- Dial your ISP and make your connection to the Internet.
- When you are connected to your ISP, dial the target server to establish
the PPTP connection.
