NOTE: Be sure to check out our Guided Setup: SRX300 Line Firewalls. Our Guided Setup picks up where this
Day One+ leaves off, providing step-by-step instructions on how to easily secure and validate your branch
location.
SRX320 Provisioning Options
It’s simple to provision and manage the SRX320 and other devices on your network. Choose the configuration tool that’s
right for you:
•Junos CLI commands. In this guide we show you how to configure the SRX320 with CLI commands that leverage the
plug and play factory defaults.
•J-Web, Juniper Networks GUI is pre-installed on the SRX320. For information on performing initial configuration using
the J-Web setup wizard see Configure SRX Devices Using the J-Web Setup Wizard in the J-Web User Guide for SRX
Series Devices.
•Juniper Networks Cloud-based applications. These applications feature plug and play to quickly get you up and running
on the network:
•Juniper Sky™ Enterprise, Juniper Networks-hosted public cloud-based Software as a Service (SaaS) solution. You’ll
need to have a Juniper Sky Enterprise subscription service before you can use it to configure the SRX320. For more
information, check out the Juniper Sky Enterprise Getting Started Guide.
•Contrail Service Orchestration (CSO). If you're using Junos OS Release 19.2 or earlier, you can use Juniper Networks
Network Service Controller to configure the SRX320 with ZTP. Network Service Controller is a component of CSO.
See Configure the Device Using ZTP with Juniper Networks Network Service Controller.
To use CSO, you’ll need an authentication code. See the Contrail Service Orchestration (CSO ) Deployment Guide.
Initial Configuration Using the CLI
IN THIS SECTION
Connect to the Serial Console Port | 8
Perform Initial Configuration | 9
Congratulations! Your SRX is Up and Running | 11

You can use the console port on the SRX to do the initial configuration. This section assumes you start from a factory
default configuration. See SRX320 Firewall Hardware Guide for details on the SRX320 factory default configuration.
After you configure the SRX320, you can log in on a local LAN port, or remotely over the WAN interface, to manage and
configure the SRX using the CLI or J-Web.
We recommend that you use the ge-0/0/0 interface for WAN connectivity on the SRX320. By default this interface is
set to receive its Internet access configuration from the service provider.
NOTE: This examples assumes you are using DHCP to configure the WAN interface. If the WAN provider does
not support DHCP ypu’ll need to manually configure the WAN interface and related static routing. See Junos
Initial Configuration.
Have this information handy before you begin the initial configuration:
•Root password
•Hostname
Connect to the Serial Console Port
1. Plug one end of the Ethernet cable into the RJ-45 to DB-9 serial port adapter for your SRX320.
NOTE: We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable
as part of the device package. If you require a console cable, you can order it separately with the part number
JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).
2. Plug the RJ-45 to DB-9 serial port adapter into the serial port on the management device.
3. Connect the other end of the Ethernet cable to the serial console port on the SRX320.
8

4. Start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal) and select the
appropriate COM port to use (for example, COM1).
5. Verify that the serial port settings are set to the default:
•Baud rate—9600
•Parity—N
•Data bits—8
•Stop bits—1
•Flow control—none
NOTE: You can also connect to the SRX320 using a mini-USB console port. See the SRX320 Hardware Guide.
Perform Initial Configuration
1. Login as the root user and start the CLI. You don't need a password if you're running the factory default.
login: root
root@%cli
root>
NOTE: You can view the factory-default settings with the show configuration operational mode command.
2. Enter configuration mode.
root> configure
[edit]
root#
3. Since you're doing the initial configuration manually, you'll need to remove ZTP from the configuration. This stops the
periodic log messages that report on ZTP status.
Set the root authentication password and commit the change to deactivate ZTP.
[edit]
root# delete chassis auto-image-upgrade
root# delete system phone-home
root# set system root-authentication plain-text-password
New password: password
9

Retype new password: password
Issue the commit command to activate the candidate configuration that disables ZTP:
[edit]
root# commit
4. Enable root login over SSH, and allow SSH access over the WAN interface (ge-0/0/0).
[edit]
root# set system services ssh root-login allow
root# set security zones security-zone untrust interfaces ge-0/0/0.0 host-inbound-traffic system-services ssh
5. Configure the hostname.
[edit]
root# set system host-name host_name
6. That’s it! The initial configuration is complete. Commit the configuration to activate the changes on the SRX.
[edit]
root# commit

Congratulations! Your SRX is Up and Running
Your SRX320 is now online and providing secure Internet access to devices attached to the LAN ports. You can manage
the device locally and remotely, using the Junos CLI, J-Web, or a cloud based provisioning service. Here's what your
network looks like:

A few things to keep in mind about your new SRX320 branch network:
•You access the SRX CLI or J-Web user interface locally using the 192.168.1.1 address. To access the SRX remotely,
specify the IP address assigned by the WAN provider. Simply issue a show interfaces ge-0/0/0 terse CLI command to
confirm the address in use by the WAN interface.
•Devices attached to the LAN ports are configured to use DHCP. They receive their network configuration from the
SRX. These devices obtain an IP address from the 192.168.1.0/24 address pool and use the SRX as their default gateway.
•All LAN ports are in the same subnet with Layer 2 connectivity. All traffic is permitted between trust zone interfaces.
•All traffic originating in the trust zone is permitted in the untrust zone. Matching response traffic is allowed back from
the untrust to the trust zone. Traffic that originates from the untrust zone is blocked from the trust zone.
•The SRX performs source NAT (S-NAT) using the WAN interface’s IP for traffic sent to the WAN that originated from
the trust zone.
•Traffic associated with specific system services (HTTPS, DHCP, TFTP, and SSH) is permitted from the untrust zone to
the local host. All local host services and protocols are allowed for traffic that originates from the trust zone.
