Required Configuration - Juniper Networks NETSCREEN-5GT ADSL Guide De L'utilisateur

The NetScreen device allows any type of traffic to the Internet that originates from
devices in your network, but does not allow any traffic that originates in the Internet to
reach your network. You can configure additional restrictions; refer to
Additional Policies" on page

EQUIRED ONFIGURATION
This section describes the following configurations that you need to complete to use the
NetScreen-5GT ADSL with its default settings:
• Configuring the ADSL interface
• Setting the date and time on the NetScreen device
• Changing the default administrator name and password
Note: If you have any problems completing a configuration and you need to restore the
device to its default settings, see
Configuring the ADSL Interface
Your network uses the ADSL interface "adsl1" on the NetScreen device to connect to the
service provider's network through an Asynchronous Transfer Mode (ATM) virtual circuit.
You can configure additional virtual circuits by creating ADSL subinterfaces (see
Virtual Circuits" on page 21
In the WebUI, navigate to the Network > Interfaces page to see a list of the current
interfaces on the NetScreen device. If you are using a Telnet or Console session, enter the
CLI command get interface. You should see that the adsl1 interface is bound to the
Untrust zone. If you used the Initial Configuration Wizard to configure the device, there
may be an IP address and netmask already assigned to the adsl1 interface.
Note: If you do not want to use the ADSL interface, you can bind it to the Null zone. If you
use the Initial Configuration Wizard to configure the device, you can choose to not use the
ADSL interface as the default interface to the Untrust zone.
You must configure the adsl1 interface to enable the NetScreen device to connect to the
service provider's network. To do this, you must obtain the following information from
your service provider:
• Virtual Path Identifier and Virtual Channel Identifier (VPI/VCI) values
• Asynchronous Transfer Mode (ATM) Adaptation Layer 5 (AAL5) multiplexing
method, which can be one of the following:

Virtual Circuit (VC)-based multiplexing, in which each protocol is carried
over a separate ATM virtual circuit (this is the default multiplexing
method)
Logical Link Control (LLC) encapsulation, which allows several protocols
to be carried on the same ATM virtual circuit
