Juniper SRX320 Manual

1
The SRX320 Services Gateway consolidates security, routing, switching,
and WAN interfaces for small distributed enterprises. With advanced threat
mitigation capabilities, the services gateway provides cost-eective and secure
connectivity across distributed enterprises.
With a desktop form-factor chassis, the SRX320 Services Gateway has six
1-Gigabit Ethernet ports, two 1-Gigabit Ethernet SFP ports, 4 GB of DRAM
memory, and 8 GB of flash memory. The SRX320 Services Gateway is available
with or without Power over Ethernet (PoE) capability. In the PoE model, the six
Ethernet ports are PoE capable.

2. Place the power supply adapter in the tray.
3. Have one person grasp the sides of the device, lift it, and position it in the rack.
Align the bottom hole in each mounting bracket with a hole in each rack rail,
making sure that the chassis is level.
4. Have a second person install a mounting screw into each of the two aligned
holes. Use a number-3 Phillips screwdriver to tighten the mounting screws.

6. Verify that the mounting screws on one side of the rack are aligned with the
mounting screws on the opposite side and that the device is level.
The SRX320 Services Gateway can also be mounted on a desk or a wall. For
details, see the SRX320 Services Gateway Hardware Guide.
NOTE: The mounting kits are not shipped with the device and must be
ordered separately.
Connect the Grounding Cable (Optional)
1. Attach an ESD strap to an ESD point and place the other end of the strap
around your bare wrist.
2. Connect the grounding cable to a proper earth ground.
3. Place the grounding cable lug over the grounding point on the rear of the
chassis.
NOTE: A licensed electrician must attach a cable lug to the grounding
cable. A cable with an incorrectly attached lug can damage the device.
4. Secure the grounding cable lug to the grounding point with the screw.

Configure the Device Using J-Web
To configure the device using J-Web, follow the steps in this section.
Connect the Management Device
1. To configure the device using J-Web (recommended), connect any of the
network ports numbered 0/1 through 0/5 to the Ethernet port on the
management device, using an RJ-45 cable.

Ethernet port
RJ-45 cable Ethernet port
NOTE: The ge-0/0/0 interface (port 0/0) is a WAN interface. Do not
use this port for the initial configuration procedure.
If you will be using the Default setup mode to configure the device, use
only port 0/1. For information on the setup modes, see the following
Log in to J-Web section.
2. The services gateway functions as a DHCP server and automatically assigns
an IP address to the management device. Ensure that the management
device acquires an IP address on the 192.168.1.0/24 subnetwork from the
device.
If an IP address is not assigned to the management device, manually
configure an IP address in the 192.168.1.0/24 subnetwork. Do not assign
the 192.168.1.1 IP address to the management device, as this IP address is
assigned to the services gateway. By default, the DHCP server is enabled
on the L3 VLAN interface, irb.0 (interface ge-0/0/1 to ge-0/0/5). which is
configured with an IP address of 192.168.1.1/24.

Log In to J-Web
1. Access the J-Web interface using the URL https://192.168.1.1. The
recommended browser is Internet Explorer version 9 or 10, or Mozilla Firefox
version 38 (or later).
2. Select one of the following setup modes:
•Guided Setup (uses a dynamic IP address)—Allows you to set up the
device in a custom security configuration. You can select either the Basic
or the Expert option.
•Default Setup (uses a dynamic IP address)—Allows you to quickly set up
the device with the default configuration. Any additional configuration can
be done after the wizard setup is completed.
•High Availability—Allows you to set up a chassis cluster with a default basic
configuration.
NOTE: The initial configuration requires that you specify the device
name and root password. You can skip all the other steps and go directly
to the Confirm & Apply page to apply the configuration.
Configure the Device Using the Guided Setup Mode
1. Connect port 0/0 to the ISP device to obtain a dynamic IP address.
2. Select the expertise level as Basic or Expert.
The following table compares the Basic and Expert levels:

3. Configure the basic settings:
a. Device name
b. Password for the root account
c. Time
4. Configure the security topology:
a. Internet zone (Untrust)
b. Internal zones (Trust)
c. DMZ
5. Configure the security policy:
a. Licenses (Security services)
b. DMZ policy
c. Internet and internal policies
d. Remote VPN
6. Configure Network Address Translation:
a. Internal Source NAT
b. Internal Destination NAT
c. DMZ Destination NAT
7. Review the settings and click Apply Settings.
NOTE: Check the connectivity from the management device to the SRX
Series device. You might lose connectivity to the SRX Series device if
you have changed the internal zone IP. Click the URL for reconnection
instructions on the Confirm & Apply page to reconnect, if required.
8. Click Done to complete the setup.
Configure the Device Using the Default Setup Mode
1. Connect port 0/0 to the ISP device to obtain a dynamic IP address.
NOTE: Verify that the management device is connected to port 0/1 on
the services gateway before proceeding to the next step.
2. Configure the basic settings – device name, root account information, and
system time.

How to Set Up Your SRX320 Services Gateway 7
3. Configure the security policy – licenses.
4. Review the settings and click Apply Settings. Click Done to complete the
setup.
NOTE: Check the connectivity from the management device to the SRX
Series device. You might lose connectivity to the SRX Series device if
you have changed the internal zone IP. Click the URL for reconnection
instructions on the Confirm & Apply page to reconnect, if required.
You can also configure the services gateway using the CLI, by connecting to the
Console port. For details, see the SRX320 Services Gateway Hardware Guide.
Verify the Settings
Access http://www.juniper.net to ensure that you are connected to the Internet.
This connectivity ensures that you can pass trac through the services gateway.
If the page does not load, perform the following checks to see if you can identify
the problem:
•Verify your configuration settings, and ensure that you have applied the
configuration.
•Check if the ISP-supplied device connecting your SRX Series device to the
Internet is turned on and working properly. Try turning it o and on again.
After you complete these steps, the SRX Series device can pass trac from any
trust port to the untrust port.
NOTE: With this step, you have successfully completed the initial
configuration, and your SRX320 Services Gateway is ready for use.
Change the Configuration Settings (Optional)
After you complete the initial setup configuration, you can access the J-Web
setup wizard by clicking Configuration Wizards > Set Up. You can either edit
the existing settings or create a new configuration. If you choose to create a
new configuration, then all the current configuration in the services gateway
will be deleted.

Power O the Device
You can power o the device in one of the following ways:
• Graceful shutdown—Press and immediately release the Power button.
• Forced shutdown—Press the Power button, and hold it for 10 seconds.
After powering o a power supply, wait at least 60 seconds before turning it
back on.
Reset the Configuration
Use the RESET CONFIG button to restore the device to the factory-default
configuration or to a rescue configuration. To press the RESET CONFIG button,
insert a small probe (such as a straightened paper clip) into the pinhole on the
front panel.
Pressing and quickly releasing the RESET CONFIG button loads and commits
the rescue configuration. The rescue configuration is a previously committed,
valid configuration set through J-Web or the CLI. The STATUS LED is solid amber
during this time.
Pressing and holding the RESET CONFIG button for 15 seconds or more,
until the STATUS LED is solid amber, deletes all configurations (backup
configurations and rescue configuration), and loads and commits the factory
configuration.
NOTE: After resetting the device, check the device status by viewing the
LEDs on the front panel. For information on the LED states, see the Power
On the Device section.
