Example— Configuration for Dial-up PPP

The tasks to be introduced in Chapter 31, Setting Up a Dial-up PPP Link (Tasks) execute a small company's requirement to let employees work at home a few days a week. Some employees require the Solaris operating environment on their home machines. They also need to log in remotely to their work machines on the corporate intranet.

The tasks set up a basic dial-up link with the following features:

The next figure shows the link that is set up in Chapter 31, Setting Up a Dial-up PPP Link (Tasks).

Figure 30–1 Sample Dial-up Link

In this figure, a remote host dials out through its modem over telephone lines to Big Company's intranet. Another host is configured to dial out to Big Company but currently is inactive. One at a time, the calls from remote users are answered by the modem that is attached to the dial-in server at Big Company. A PPP connection is established between the peers. Then the dial-out machine can remotely log in to a host machine on the intranet.
