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).
