Configuring PPTP

The Point-to-Point Tunneling Protocol (PPTP) is supported by Nortel Networks and several other vendors. The Microsoft PPTP client is available for Windows* 95, Windows NT Workstation (Version 4.0), Windows ME, and Windows NT* Server (except Version 3.51). The Microsoft PPTP client is bundled with Windows 98 software. Network TeleSystems (www.nts.com) provides tunneling product support for Windows 3.1 and Macintosh* operating systems.

You can obtain the PPTP client upgrade for Windows 95 directly from Microsoft (www.microsoft.com). Installation instructions are also available from this site.

• Connections can be made from a range of clients without requiring special ISP services.
• The PPTP client is available for the most common client operating systems.
• PPTP supports IP address translation using encapsulation, support for IPX tunneling, and RC4 encryption (either 56- or 128-bit, within the limits of United States export law).
