POINT TO POINT TUNNELING CONNECTIONS

Introduction

If local workstations require connections to the outside world via the modem’s Ethernet interface and your ISP or corporate network administrator requires that you use a dial-up connection, you must use Point-to-Point Tunneling Protocol (PPTP). This protocol enables Point-to-Point Protocol (PPP) over an Ethernet interface.

PPP/PPTP Network

Figure 25 provides an overview of the end-to-end network protocol.

The dial-up icons you create on the PC allow you to establish connections to your corporate network or to the Internet via your local ISP. Double-clicking a dial-up icon establishes a local PPTP tunnel from your PC over your local network to the modem. The modem terminates this tunnel and relays all traffic inside it to a free ATM connection or to an ATM connection you select.
