Basic Encryption Scenario

This example shows how you would create an encrypted tunnel between two systems, each behind a routing Screen. Figure 5-1 shows a VPN connecting the San Francisco and Hong Kong segments of the network. In the diagram, an encrypted tunnel across the Internet exists between Screens sf-screen and hk-screen. The Screens encrypt and decrypt traffic on behalf of the systems behind them (sf-host1 and hk-host1 in this example).
