Getting Started
StoneGate System Components
The illustration above shows all available StoneGate components. Out of
these, you need the following components to have an operational
Firewall/VPN system:
1. A Management Server, which stores the configuration of the
system. In most environments, it is best to have just one common
Management Server for all firewall and IPS engines.
2. At least one Log Server to handle and store logs and alerts (can
be installed simultaneously on the same machine with the
Management Server).
3. At least one Management Client that you use to connect to the
Management Server to change settings and monitor the system.
4. The Firewall Engines that handle the actual traffic processing (in
this case, the StoneGate appliance).
5. Licenses for each component except the Management Client(s).
Generate appliance licenses at the Stonesoft website with the
POS (proof-of-serial-number) code attached to the appliance.
The Web Portal Server is an optional component that is available on
separate order.
StoneGate IPS engines can be added to the same system for unified
management and incident handling.

Safety Precautions
The following safety information and procedures must be followed
whenever working with the StoneGate Appliance. However, please be
advised that StoneGate Appliances are not end-user serviceable, and
you must never open the appliance covers for any reason. Doing so may
lead to serious injury and will void any hardware warranty that may be
associated with your appliance.
Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself
from harm and the appliance from damage:
• Be aware of the locations of the power on/off switch as well as the
room's emergency power-off switch, disconnection switch, or
electrical outlet. If an electrical accident occurs, you can then quickly
cut power to the system.
• Do not work alone when working with high voltage components.
• Use only one hand when working with powered-on electrical
equipment. This is to avoid making a complete circuit, which will
cause electrical shock. Use extreme caution when using metal tools,
which can easily damage any electrical components or circuit boards
they come into contact with.
• Do not use mats designed to decrease electrostatic discharge as
protection from electrical shock. Instead, use rubber mats that have
been specifically designed as electrical insulators.
• The power supply cord must include a grounding plug and must be
plugged into a grounded electrical outlet.
Caution – Never open the appliance covers! There are no user
serviceable parts inside. Opening the covers may lead to serious
injury and will void the warranty.
General Safety Precautions
Follow these rules to ensure general safety:
• Keep the area around the appliance clean and free of clutter.
• We recommend using a regulating uninterruptible power supply (UPS)
to protect the appliance from power surges, voltage spikes and to
keep your system operating in case of a power failure.
6
Safety Precautions
ESD Precautions
Electrostatic discharge (ESD) is generated by two objects with different
electrical charges coming into contact with each other. An electrical
discharge is created to neutralize this difference, which can damage
electronic components and printed circuit boards. Use a grounded wrist
strap designed to prevent static discharge.
Note – Use a UPS (Uninterruptible Power Supply) in critical
environments with your StoneGate appliance. If after a brief power
outage your StoneGate appliance only partially starts up (for example,
the power light is on, but the appliance does not connect) turn the
appliance off for five seconds and then back on.
Operating Precautions
Care must be taken to assure that the appliance cover is in place when
the appliance is operating to ensure proper cooling. If this rule is not
strictly followed, the warranty may become void.
Operating and Storage Temperatures
The allowed operating temperature of the appliance is +5...+40ºC. The
allowed storage temperature is 0...+70ºC. Do not operate or store the
appliance in temperatures outside these limits.
Battery Information and Precautions
The appliance contains an External Li-ion battery that is meant for RTC/
BIOS CMOS data saving only.
Caution – Do not change the battery; the battery must be replaced by
authorized service personnel only. Danger of explosion if battery is
incorrectly replaced. Replacement battery must be same or equivalent
type recommended by the manufacturer. The battery must be
disposed of according to the manufacturer’s instructions. Shortcircuiting the battery may heat the battery and cause severe injuries.

Cable Types
Make sure that the cables you use are correctly rated (CAT 5e or CAT 6
in gigabit networks).
Speed/Duplex Settings
Network cards at both ends of each cable must have identical speed/
duplex settings. This also applies to the automatic negotiation setting: if
one end of the cable is set to autonegotiate, the other end must also be
set to autonegotiate. Gigabit standards require interfaces to use
autonegotiation—fixed settings are not allowed at gigabit speeds.
Connecting the Cables

Connecting the Cables
Initial Configuration
To start using the appliance, you must activate the network interfaces
and establish a secure connection to the Management Server as
outlined in the sections below.
To successfully complete this configuration, the following prerequisites
must be met:
• The Firewall element must be defined in the Management Center.
• You must have created a one-time password for this engine. See the
StoneGate Firewall/VPN Installation Guide for details.
• If you use the configuration wizard to configure the engine, you must
have created a one-time password for this engine.
• If you want to configure the engine automatically with a USB stick or
to import some of the initial configuration information in the
configuration wizard, you must have a saved initial configuration on a
USB stick.
See the StoneGate Firewall/VPN Installation Guide for details.
Note – The appliance must contact the Management Server before it
can be operational.
There are two ways to configure the engine software.
• You can configure the engine automatically with a USB stick (see
Configuring the Engine Automatically.
• If the automatic configuration is not possible or desired, you can use
the engine configuration wizard. See Using the Engine Configuration
Wizard (page 14).
Configuring the Engine Automatically
The automatic configuration requires that you have a suitable
configuration saved on a USB memory stick. See the Firewall/VPN
Installation Guide or the Online Help of the Management Client for
details.
T To configure the engine from a USB memory stick
1. Insert the USB stick that contains the configuration saved in your
Management Client in one of the USB ports on the appliance.
2. Push the Power button in the back panel to turn on the appliance.
The Power button light turns from red to blue. The appliance
automatically imports the configuration from the USB stick, and
then tries to make the initial contact to the Management Server.
Initial Configuration
13
• If the connection is successful, the appliance automatically
reboots itself and the engine configuration is finished.
If you configure the engine with a USB stick, you must set a password
for the root account in the Management Client to enable command line
access to the engine. If you want to allow remote access to the engine
using SSH, enable the SSH daemon for the engine in the Management
Client. See the Administrator’s Guide for more information.
Proceed to After Successful Management Server Contact (page 20).
If the Automatic Configuration Fails
• If the automatic configuration fails, and you do not have a display
connected, you can check for the reason in the log
(sg_autoconfig.log) written on the USB stick.
• If you see a “connection refused” error message, ensure that the
Management Server IP address is reachable from the engine and
check the IP addresses you have defined in the Management Client.
• If the configuration with the USB stick still does not succeed, follow
the instructions for the manual configuration. See Using the Engine
Configuration Wizard below.
Using the Engine Configuration Wizard
You can use the engine configuration wizard with all Management Center
and Firewall versions. If you have saved the initial configuration on a
USB stick, you can import it in the configuration wizard to reduce typing.
T To connect using a serial cable
1. Connect the serial cable supplied with the appliance to the serial
port on the appliance and to a computer.
2. On the computer, open a terminal with settings 9600bps, 8
databits, 1 stopbit, no parity.
3. Push the Power button in the back panel to turn on the appliance.
The Power button light turns from red to blue. The engine bootup
process in shown in the console and, after some time, the engine
configuration wizard starts.

initial configuration.
3. (Optional) Fill in the Key Fingerprint (also shown when you saved the
initial configuration). Filling it in increases the security of the
communications.
4. Highlight Finish and press ENTER.
The engine now tries to make initial Management Server contact.
• If you see a “connection refused” error message, ensure that the
one-time password is correct and the Management Server IP address
is reachable from the node. Save a new initial configuration if unsure
about the password.
• If the engine is unable to contact the Management Server, make sure
there are no networking problems, that all information defined in the
Firewall element corresponds to what you entered in the configuration
wizard and, if NAT is in use, that you have configured contact
addresses for NAT as explained in the Firewall/VPN Installation Guide.
Note – Once initial contact has been made, the engine receives a
certificate from the Management Center for identification. If the
certificate is deleted or expires, you must repeat the initial contact
using a new one-time password.
Initial Configuration
19
After Successful Management Server Contact
After you see a notification that Management Server contact has
succeeded or the appliance has rebooted itself after automatic
configuration with a USB stick, the firewall engine installation is
complete and the firewall is ready to receive a policy. In a while, the
firewall’s status changes in the Management Client from Unknown to No
Policy Installed, and the connection state is Connected indicating that
the Management Server can connect to the node.
The next step is creating a security policy and installing it on the engine.
See the Online Help of the Management Client for detailed instructions.
Caution – When using the command prompt, use the reboot
