Preface
The FB6000 device is the result of several years of intensive effort to create products based on state of the
art processing platforms, featuring an entirely new operating system and IPv6-capable networking software,
written from scratch in-house by the FireBrick team. Custom designed hardware, manufactured in the UK, hosts
the new software, and ensures FireBrick are able to maximise performance from the hardware, and maintain
exceptional levels of quality and reliability.
The result is a product that has the feature set, performance and reliability to handle mission-critical functions,
effortlessly handling huge volumes of traffic, supporting thousands of customer connections.
The software is constantly being improved and new features added, so please check that you are reading the
manual appropriate to the version of software you are using. This manual is for version V1.46.100.

1
Chapter 1. Introduction
1.1. The FB6000
1.1.1. Where do I start?
The FB6000 is shipped in a factory reset state. This means it has a default configuration that allows the unit
to be attached directly to a computer, or into an existing network, and is accessible via a web browser on a
known IP address for further configuration.
Besides allowing initial web access to the unit, the factory reset configuration provides a starting point for you
to develop a bespoke configuration that meets your requirements.
A printed copy of the QuickStart Guide is included with your FB6000 and covers the basic set up required to
gain access to the web based user interface. If you have already followed the steps in the QuickStart guide, and
are able to access the FB6000 via a web browser, you can begin to work with the factory reset configuration
by referring to Chapter 3.
Initial set up is also covered in this manual, so if you have not already followed the QuickStart Guide, please
start at Chapter 2.
Tip
The FB6000's configuration can be restored to the state it was in when shipped from the factory. The
procedure requires physical access to the FB6000, and can be applied if you have made configuration
changes that have resulted in loss of access to the web user interface, or any other situation where it
is appropriate to start from scratch - for example, commissioning an existing unit for a different role,
or where you've forgotten an administrative user password. It is also possible to temporarily reset the
FB6000 to allow you to recover and edit a broken configuration (though you still need to know the
password you had). You can also go back one step in the config.
The remainder of this chapter provides an overview of the FB6000's capabilities, and covers your product
support options.
Tip
The latest version of the QuickStart guide for the FB6000 can be obtained from the FireBrick website
at : http://www.firebrick.co.uk/pdfs/quickstart-6000.pdf
1.1.2. What can it do?
The FB6000 series of products is a family of high speed ISP/telco grade routers and firewalls providing a range
of specific functions.
Key features of the FB6000 family:
• 1U 19" rack mount
• Very low power consumption (typical 20W) - all important with today's power charges in data centres
• Two small fans are the only moving parts for high reliability
• Dual 120/230V AC power feed
• IPv6 built in from the start

Introduction
2
• Gigabit performance
The FB600 series are provided in a number of variants. This manual is for the FB6502. This variant includes:
• Border Gateway Protocol, to allow routes to be announced and accepted from peering BGP routers.
• SIP VoIP caller server, providing core call routing and registration functions for a voice network operator.
1.1.2.1. FB6502 Gigabit core VoIP SIP switch for ISTP use
The FB6502 acts as a core voice network switch. It provides high capacity media forwarding and SIP/2.0 VoIP
protocol handling, including registration and call routing.
The design allows the FB6502 to perform the grunt of a large scale voice network leaving external devices
(e.g. linux boxes) to make decisions and log calls, interacting via RADIUS messages. The FB6502 can work
with pools of RADIUS servers for fallback and load management.
1.1.3. Ethernet port capabilities
The FB6000 has two Ethernet network ports that operate at 1Gb/s. The ports implement auto-negotiation by
default, but operation can be fine-tuned to suit specific circumstances. The function of these ports is very
flexible, and defined by the device's configuration. The ports implement one or more interfaces.
Multiple interfaces can be implemented on a single physical port via support for IEEE 802.1Q VLANs, ideal
for using the FB6000 with VLAN-capable network switches. In this case, a single physical connection can be
made between a VLAN-capable switch and the FB6000, and with the switch configured appropriately, this
physical connection will carry traffic to/from multiple VLANs, and the FB6000 can do Layer 3 processing
(routing/firewalling etc.) between nodes on two or more VLANs.
1.1.4. Product variants in the FB6000 series
•FB6102 High capacity ping monitoring box
•FB6202 Gigabit L2TP LNS with detailed monitoring of all lines
•FB6302 Gigabit BGP router
•FB6402 Gigabit stateful firewall
•FB6502 Gigabit core VoIP SIP switch for ISTP use
•FB6602 Mobile GTPv1 GGSN/L2TP gateway
•FB6702 Tunnel endpoint / gateway
1.2. About this Manual
1.2.1. Version
Every major FB6000 software release is accompanied by a release-specific version of this manual. This manual
documents software version V1.46.100 - please refer to Section 4.3 to find out more about software releases,
and to see how to identify which software version your FB6000 is currently running.
If your FB6000 is running a different version of system software, then please consult the version of this manual
that documents that specific version, as there may be significant differences between the software versions.
Also bear in mind that if you are not reading the latest version of the manual (and using the latest software
release), references in this manual to external resources, such as the FireBrick website, may be out of date.

Introduction

website [http://www.firebrick.co.uk/software.php?PRODUCT=6000]. This includes the revision history for all
software releases.
1.2.2. Intended audience
This manual is intended to guide FB6000 owners in configuring their units for their specific applications. We
try to make no significant assumption about the reader's knowledge of FireBrick products, but as might be
expected given the target market for the products, it is assumed the reader has a reasonable working knowledge
of common IP and Ethernet networking concepts. So, whether you've used FireBrick products for years, or
