Before you make a connection, in order to use PPTP to connect to a server securely across the Internet, the PPTP protocol must be loaded. To load the PPTP protocol, do the following:
- ClickÂ Start, point toÂ Settings, clickÂ Control Panel, and then double-clickÂ Network.
- On theÂ ProtocolsÂ tab, add PPTP.
- After the protocol is loaded, Remote Access Service (RAS) is invoked. You must add at least one VPN port as a port in the RAS setup interface.
- At this time, specify which protocols you want to run for that VPN port. You can install up to 256 VPN ports. Each VPN can be connected to a network.
- Make sure that at least one VPN is configured for dial-out. One other consideration is that you must know what protocol is used on the receiving PPTP server, and select that protocol and configure it for the VPN port.
- Re-apply the last applied service pack.
To make the connection, do the following:
- Assuming that you have a phone book entry for your ISP, create a phone book entry for the PPTP server. The actual phone number is the name of the host or an IP address. Using the IP address of the PPTP RAS server is ideal. There may be name resolution considerations otherwise. Make sure that the Dial Using dialog has a RASPPTPM VPN port assigned to it.
- Dial the ISP using the standard phone book entry created for the ISP. When you have established a connection, dial the IP address or host name of the computer.
