Configure the Device
The 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:
„ “Access the Device” on page 18
„ “Default Device Settings” on page 21
„ “Basic Device Configuration” on page 23
„ “Wireless Configuration” on page 27
„ “Mini PIM Configuration” on page 30
„ “Basic Firewall Protections” on page 37
„ “Verify External Connectivity” on page 38
„ “Reset the Device to Factory Defaults” on page 38
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, 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
