Network requirements
Figure 31 presents a scenario where:
Router and NT Server are interconnected via modems across a PSTN network.
■
NT Server is assigned the IP address of 100.1.1.254/24.
■
Router accepts the address assigned by NT Server.
■
Configure PPP callback with C-DCC between Router and PC, specifying Router as
the callback client and NT Server as the callback server to make return calls
according to dialer routes.
