Configuring the Device
ScreenOS software is preinstalled on an SSG 20 device. When the device is powered
on, it is ready to be configured. While the device has a default factory configuration
that allows you to initially connect to the device, you need to perform further
configuration for your specific network requirements.
This chapter contains the following sections:
“Accessing a Device” on page 28
“Default Device Settings” on page 31
“Basic Device Configuration” on page 33
“Basic Wireless Configuration” on page 37
“Mini PIM Configuration” on page 41
“Basic Firewall Protections” on page 48
“Verifying External Connectivity” on page 48
“Resetting a Device to Factory Defaults” on page 49
NOTE: After you configure a device and verify connectivity through the remote network,
you must register your product at www.juniper.net/support/ so certain ScreenOS
services, such as Deep Inspection Signature Service and Antivirus (purchased
separately), can be activated on the device. After registering your product, use the
WebUI to obtain the subscription for the service. For more information about
registering your product and obtaining subscriptions for specific services, refer to
the Fundamentals volume of the Concepts & Examples ScreenOS Reference Guide for
the ScreenOS version running on the device.
