Chapter 3 Configuring the Device

CONNECTING THE DEVICE AS A SINGLE SECURITY GATEWAY

There are many ways to connect a NetScreen-200 Series device to your network system. In most cases, the device serves as a single security gateway that protects at least one LAN (usually connected to the device from a switch or a hub).

Connectivity Examples

In the following example, a NetScreen-208 device connects to the protected LAN through ethernet1 (bound to the Trust security zone). The device connects externally to a router through ethernet3 (bound to the Untrust security zone).
