Chapter 1: Introduction
1.1 Overview
Congratulations on purchasing Firetunnel 30 Router from Black Box. Combining a
router with an Ethernet network switch, Firetunnel 30 is a state-of-the-art device
that provides everything you need to get your network connected to the Internet
over your Cable or DSL connection quickly and easily. The Quick Start Wizard and
DHCP Server will get first-time users up and running with minimal fuss and
configuration, while sophisticated Quality of Service (QoS) and Load Balancing
features grant advanced users total control over their network and Internet
connection.
This manual illustrates the many features and functions of Firetunnel 30, and even
takes you through the various ways you can apply this versatile device to your home
or office. Take the time now to familiarize yourself with Firetunnel 30.
1.2 Product Highlights
1.2.1 Increased Bandwidth, Scalability and Resilience
With integrated Dual WAN ports, Firetunnel 30 combines two broadband lines such
as DSL or Cable into one Internet connection, providing optimal bandwidth sharing
for multiple PCs on your network, or allowing maximum reliability with network
redundancy. Load Balancing enables Firetunnel 30 to efficiently balance network
traffic across two connections, ideal for small-to-medium businesses that require
increased bandwidth, network scalability, and resilience for mission-critical network
and Internet applications. Auto failover can also be configured to ensure smooth,
continuous service should one connection fail, providing maximum business uptime
and productivity, plus uninterrupted service for you and your customers.
1.2.2 Virtual Private Network Support
Firetunnel 30 supports comprehensive IPSec & PPTP VPN protocols for businesses to
establish private encrypted tunnels over the Internet to ensure data transmission
security among multiple sites, such as a branch office or dial-up connection. IPSec
VPN is up to 30 simultaneous IPSec VPN connections are possible on Firetunnel 30,

with performance of up to 30Mbps. PPTP VPN is up to 4 simultaneous PPTP VPN
connections are possible on Firetunnel 30, with performance of up to 10Mbps.
1.2.3 Advanced Firewall Security
Aside from intelligent broadband sharing, Firetunnel 30 offers integrated firewall
protection with advanced features to secure your network from outside attacks.
Stateful Packet Inspection (SPI) determines if a data packet is permitted to enter
the private LAN. Denial of Service (DoS) prevents hackers from interrupting
network services via malicious attacks. In addition, Firetunnel 30 firewall can be
configured to alert you via email should your network come under fire, offering both
tight network security and peace of mind.
1.2.4 Intelligent Bandwidth Management
Firetunnel 30 utilizes Quality of Service (QoS) to give you full control over the
priority of both incoming and outgoing data, ensuring that critical data such as
customer information moves through your network, even while under a heavy load.
Transmission speeds can be throttled to make sure users are not saturating
bandwidth required for mission-critical data transfers. Priority types of upload data
can also be changed, allowing Firetunnel 30 to automatically sort out actual speeds
for unmatched convenience.

1.3.3 Rack Mounting
To rack mount Firetunnel 30, carefully secure the device to your rack on both sides
using the included brackets and screws. See the diagram below for a more detailed
explanation.
1.3.4 Cabling
Most Ethernet networks currently use unshielded twisted pair (UTP) cabling. The
UTP cable contains eight conductors, arranged in four twisted pairs, and terminated
with an RJ45 type connector.
One of the most common causes of networking problems is bad cabling. Make sure
that all connected devices are turned on. On the front panel of Firetunnel 30, verify
that the LAN link and WAN line LEDs are lit. If they are not, check to see that you are
using the proper cabling.

Chapter 2: Router Applications
2.1 Overview
Your Firetunnel 30 router is a versatile device that can be configured to not only
protect your network from malicious attackers, but also ensure optimal usage of
available bandwidth with Quality of Service (QoS) and both Inbound and Outbound
Load Balancing. Alternatively, Firetunnel 30 can also be set to redirect incoming and
outgoing network traffic with the Fail Over capability, ensuring minimal downtime
and increased reliability.
The following chapter describes how Firetunnel 30 can work for you.
2.2 Bandwidth Management with QoS
Quality of Service (QoS) gives you full control over which types of outgoing data
traffic should be given priority by the router. By doing so, the router can ensure that
latency-sensitive applications like voice, bandwidth-consuming data like gaming
packets, or even mission critical files efficiently move through the router even under
a heavy load. You can throttle the speed at which different types of outgoing data
pass through the router. In addition, you can simply change the priority of different
types of upload data and let the router sort out the actual speeds.
2.2.1 QoS Technology
QoS generally involves the prioritization of network traffic. QoS is comprised of
three major components: Classifier, Meter, and Scheduler. Each of these
components has a distinct role in ensuring that incoming and outgoing data is
managed according to user specifications.
The Classifier analyses incoming packets and marks each one according to
configured parameters. The Meter communicates the drop priority to the Scheduler
and measures the temporal priorities of the output stream against configured
parameters. Finally, the Scheduler schedules each packet for transmission based on
information from both the Classifier and the Meter.

2.2.2 QoS Policies for Different Applications
By setting different QoS policies according to the applications you are running, you
can use Firetunnel 30 to optimize the bandwidth that is being used on your network.
Restricted PC
Normal PCs
VoIP

As illustrated in the diagram above, applications such as Voiceover IP (VoIP) require
low network latencies to function properly. If bandwidth is being used by other
applications such as an FTP server, users using VoIP will experience network lag
and/or service interruptions during use. To avoid this scenario, this network has
assigned VoIP with a guaranteed bandwidth and higher priority to ensure smooth
communications. The FTP server, on the other hand, has been given a maximum
bandwidth cap to make sure that regular service to both VoIP and normal Internet
applications is uninterrupted.
2.2.3 Guaranteed / Maximum Bandwidth
Setting a Guaranteed Bandwidth ensures that a particular service receives a
minimum bandwidth. For example, you can configure Firetunnel 30 to reserve
10000 kbps of the available bandwidth for a particular computer on the network to
transfer files.
Alternatively you can set a Maximum Bandwidth to restrict a particular application
to a fixed percentage of the total throughput. Setting a Maximum Bandwidth of
20000 kbps for a file sharing program will ensure that no more than 20000 kbps of
the available bandwidth will be used for file sharing.

2.2.4 Policy Based Traffic Shaping
Policy Based Traffic Shaping allows you to apply specific traffic policies across a
range of IP addresses or ports. This is particularly useful for assigning different
policies for different PCs on the network. Policy based traffic shaping lets you better
manage your bandwidth, providing reliable Internet and network service to your
organization.

19
2.2.5 Priority Bandwidth Utilization
Assigning priority to a certain service allows Firetunnel 30 to give either a higher or
lower priority to traffic from this particular service. Assigning a higher priority to an
application ensures that it is processed ahead of applications with a lower priority
and vice versa.
2.2.6 Management by IP or MAC address
Firetunnel 30 can also be configured to apply traffic policies based on a particular IP
or MAC address. This allows you to quickly assign different traffic policies to a
specific computer on the network.

2.2.7 DiffServ (DSCP Marking)
DiffServ (a.k.a. DSCP Marking) allows you to classify traffic based on IP DSCP values.
Other interfaces can match traffic based on the DSCP markings. DSCP markings are
used to decide how packets should be treated, and is a useful tool to give
precedence to varying types of data.
