Alcatel Carrier Internetworking Solutions 1000 ADSL manual Establishing PPP/PPTP Connections

Page 49

Because PPTP tunneling is based on the IP protocol, an IP connection between your local PCs and the modem must exist before setting up a local tunnel. Configuration of IP functions in the modem is described in the CHANGING THE MODEM SETTINGS section (click on that section's heading to return here.)

Note:

Various platforms support PPTP. Subsequent examples are provided for Windows 95, Windows 98, and Windows NT. Other operating systems are not covered.

Establishing PPP/PPTP Connections

Double-clicking a previously created connection icon is all that is required to connect to your ISP or your corporate network.

By default, the modem is configured for eight PPP/ATM connections. However, check with your ISP or corporate network administrator to ensure that these connections are cross-connected in the wide area network to enable end-to-end connections.

With PPP/PPTP, you indicate which remote destination you want to connect to. This requires you to modify the VPN Server field in the Connect To window as described next.

Any Connection

If you leave the VPN Server field unchanged (with only the IP address of the modem or its corresponding name visible), the modem automatically connects you to one of the free ATM channels when you click Connect (see figure 26). This is the simplest connection and works best if all the ATM channels are connected to the same remote destination (see figure 27).
