Chapter 1: Introduction
1.1 Overview
Congratulations on purchasing BiGuard 30 Router from Billion. Combining a router
with an Ethernet network switch, BiGuard 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 BiGuard 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 BiGuard 30.
1.2 Product Highlights
1.2.1 Increased Bandwidth, Scalability and Resilience
With integrated Dual WAN ports, BiGuard 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 BiGuard 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
BiGuard 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 BiGuard 30,
with performance of up to 30Mbps. PPTP VPN is up to 4 simultaneous PPTP VPN
11
connections are possible on BiGuard 30, with performance of up to 10Mbps.
1.2.3 Advanced Firewall Security
Aside from intelligent broadband sharing, BiGuard 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, BiGuard 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
BiGuard 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 BiGuard 30 to automatically sort out actual speeds for
unmatched convenience.

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 BiGuard 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 BiGuard 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, BiGuard 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 BiGuard 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.
16
2.2.2 QoS Policies for Different Applications
By setting different QoS policies according to the applications you are running, you
can use BiGuard 30 to optimize the bandwidth that is being used on your network.
VoIP
Normal PCs
Restricted PC
As illustrated in the diagram above, applications such as Voiceover IP (VoIP) require
17
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 percentage of bandwidth. For example, you can configure BiGuard 30 to
reserve 10% 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 20%
for a file sharing program will ensure that no more than 20% 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
18
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.
2.2.5 Priority Bandwidth Utilization
Assigning priority to a certain service allows BiGuard 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.
19
2.2.6 Management by IP or MAC address
BiGuard 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)
20
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.
2.2.8 DSCP (Matching)
Just like the DSCP Marking, DSCP is used on traffics (Both inbound rules and
outbound rules have DSCP matching). DSCP matching is used to identify traffic for
the rule. (It is just like what source IP and destination IP do). When this option of the
QoS rule is selected, the QoS rule will only be applied to the packets whose DSCP
field’s IP header matches the criteria selected. These markings can be used to identify
traffic within the network.
2.3 Outbound Traffic
This section outlines some of the ways you can use BiGuard 30 to manage outbound
traffic.
2.3.1 Outbound Fail Over
Configuring BiGuard 30 for Outbound Fail Over allows you to ensure that outgoing
traffic is uninterrupted by having BiGuard 30 default to WAN2 should WAN1 fail.

In the above example, PC 1 (IP_192.168.2.2) and PC 2 (IP_192.168.2.3) are
213.10.10.2
connected to the Internet via WAN1 (IP_230.100.100.1) on BiGuard 30. Should
WAN1 fail, Outbound Fail Over tells BiGuard 30 to reroute outgoing traffic to WAN2
(IP_213.10.10.2). Configuring your BiGuard 30 for Outbound Fail Over provides a
more reliable connection for your outgoing traffic.
Please refer to appendix H for example settings.
2.3.2 Outbound Load Balancing
Outbound Load Balancing allows BiGuard 30 to intelligently manage outbound
traffic based on the amount of load of each WAN connection.

In the above example, PC 1 (IP_192.168.2.2) and PC 2 (IP_192.168.2.3) are
connected to the Internet via WAN1 (IP_230.100.100.1) and WAN2
(IP_213.10.10.2) on BiGuard 30. You can configure BiGuard 30 to balance the load
of each WAN port with one of two mechanisms:
1. Session (by session/by traffic/weight of link capability)
2. IP Hash (by traffic/weight of link capability)
The IP Hash mechanism will ensure that the traffic from the same source IP address
and destination IP address will go through the same WAN port. This is useful for
some server applications that need to identify the source IP address of the client.
By balancing the load between WAN1 and WAN2, your BiGuard 30 can ensure that
outbound traffic is efficiently handled by making sure that both ports are equally
sharing the load, preventing situations where one port is completely saturated by
outbound traffic.
Please refer to appendix H for example settings.
2.4 Inbound Traffic
Learn how BiGuard 30 can handle inbound traffic in the following section.
2.4.1 Inbound Fail Over
Configuring BiGuard 30 for Inbound Fail Over allows you to ensure that incoming
traffic is uninterrupted by having BiGuard 30 default to WAN2 should WAN1 fail.

In the above example, an FTP Server (IP_192.168.2.2) and an HTTP Server
(IP_192.168.2.3) are connected to the Internet via WAN1 (ftp.billion.dyndns.org)
on BiGuard 30. A remote computer is trying to access these servers via the Internet.
Under normal circumstances, the remote computer will gain access to the network
via WAN1. Should WAN1 fail, Inbound Fail Over tells BiGuard 30 to reroute incoming
traffic to WAN2 by using the Dynamic DNS mechanism. Configuring your BiGuard 30
for Inbound Fail Over provides a more reliable connection for your incoming traffic.
Please refer to appendix H for example settings.
2.4.2 Inbound Load Balancing
Inbound Load Balancing allows BiGuard 30 to intelligently manage inbound traffic
based on the amount of load of each WAN connection.

(IP_192.168.2.3) are connected to the Internet via WAN1
(www.billion2.dyndns.org) and WAN2 (www.billion3.dyndns.org) on BiGuard 30.
Remote PCs are attempting to access the servers via the Internet. Using Inbound
Load Balancing, BiGuard 30 can direct incoming requests to the correct WAN port
based on group assignment. For example, a sales force can be directed to
www.billion2.dyndns.org, while the R&D group can access www.billion3.dyndns.org.
By balancing the load between WAN1 and WAN2, your BiGuard 30 can ensure that
inbound traffic is efficiently handled with both ports equally sharing the load,
preventing situations where service is slow because one port is completely
saturated by inbound traffic.
Please refer to appendix H for example settings.
2.5 DNS Inbound
Using DNS Inbound is a great way to intelligently direct network traffic.
25
ISP
DNS Inbound is a three step process. First, a DNS request is made to the router via
a remote PC. BiGuard 30, based on settings specified by the user, will direct the
requesting PC to the correct WAN port by replying the selected WAN IP address
through the built-in DNS server. The remote PC then accesses the network via the
specified WAN port. How BiGuard 30 directs this traffic through the built-in DNS
server depends on whether it is configured for Fail Over or Load Balancing.
ISP
Learn how to make DNS Inbound on BiGuard 30 work for you in the following
section.
2.5.1 DNS Inbound Fail Over
BiGuard 30 can be configured to reply the WAN2 IP address for the DNS domain
name request should WAN1 fail.

(IP_192.168.2.3) are connected to the Internet via WAN1 (IP_200.200.200.1) on
BiGuard 30. A remote computer is trying to access these servers via the Internet,
and makes a DNS request. The DNS request (www.mydomain.com
) will be sent
through WAN1 (200.200.200.1) to the built-in DNS server. The DNS server will reply
200.200.200.1 because this is the only active WAN port. Should WAN1 fail, BiGuard
30 will instead reply with WAN2’s IP address (100.100.100.1), and the remote PC
will gain access to the network via WAN2. By configuring BiGuard 30 for DNS
Inbound Fail Over, incoming requests will enjoy increased reliability when accessing
your network.
Please refer to appendix H for example settings.
2.5.2 DNS Inbound Load Balancing
DNS Inbound Load Balancing allows BiGuard 30 to intelligently manage inbound
traffic based on the amount of load of each WAN connection by assigning the IP
address with the lowest traffic load to incoming requests.

(IP_192.168.2.3) are connected to the Internet via WAN1 (IP_200.200.200.1) and
WAN2 (IP_100.100.100.1) on BiGuard 30. Remote PCs are attempting to access the
servers via the Internet by making a DNS request, entering a URL
(www.mydomain.com). Using a load balancing algorithm, BiGuard 30 can direct
incoming requests to either WAN port based on the amount of load each WAN port
is currently experiencing. If WAN2 is experiencing a heavy load, BiGuard 30
responds to incoming DNS requests with WAN1. By balancing the load between
WAN1 and WAN2, your BiGuard 30 can ensure that inbound traffic is efficiently
handled, making sure that both ports are equally sharing the load and preventing
situations where service is slow because one port is completely saturated by
inbound traffic.
Please refer to appendix H for example settings.
A typical scenario of how traffic is directed with DNS Inbound Load Balancing is
illustrated below:

In the example above, the client is making a DNS request. The request is sent to the
DNS server of BiGuard 30 through WAN2 (1). WAN2 will route this request to the
embedded DNS server of BiGuard 30 (2). BiGuard 30 will analyze the bandwidth of
both WAN1 and WAN2 and decide which WAN IP to reply to the request (3). After the
decision is made, BiGuard 30 will route the DNS reply to the user through WAN2 (4).
The user will receive the DNS reply with the IP address of WAN1 (5). The browser
will initiate an HTTP request to the WAN1 IP address (6). The HTTP request will be
send to BiGuard 30’s URL Host Map (7). The Host Map will then redirect the HTTP
request to the HTTP server (8). The HTTP server will reply (9). The URL Host Map will
route the packet through WAN1 to the user (10). Finally, the client will receive an
HTTP reply packet (11).
2.6 Virtual Private Networking
A Virtual Private Network (VPN) enables you to send data between two computers
across a shared or public network in a manner that emulates the properties of a
point-to-point private link. As such, it is perfect for connecting branch offices to
headquarters across the Internet in a secure fashion.
29
The following section discusses Virtual Private Networking with BiGuard 30.
2.6.1 General VPN Setup
There are typically three different VPN scenarios. The first is a Gateway to
Gateway setup, where two remote gateways communicate over the Internet via a
secure tunnel.
100.100.100.1
192.168.2.x
Secure Tunnel
200.200.200.1
192.168.3.x
The next type of VPN setup is the Gateway to Multiple Gateway setup, where one
gateway (Headquarters) is communicating with multiple gateways (Branch Offices)
over the Internet. As with all VPNs, data is kept secure with secure tunnels.
200.200.200.1
192.168.3.x

Secure Tunnel
100.100.100.1
Secure Tunnel
201.201.201.1
192.168.4.x
The final type of VPN setup is the Client to Gateway. A good example of where this
can be applied is when a remote sales person accesses the corporate network over
a secure VPN tunnel.

BiGuard Client
VPN provides a flexible, cost-efficient, and reliable way for companies of all sizes to
stay connected. One of the most important steps in setting up a VPN is proper
30
planning. The following sections demonstrate the various ways of using BiGuard 30
to setup your VPN.
2.6.2 VPN Planning - Fail Over
Configuring your VPN with Fail Over allows BiGuard 30 to automatically default to
WAN2 should WAN1 fail.

BiGuard30
200.200.200.1
biguard.billion.com
BiGuard10
192.168.3.x
After Fail Over
Because the dynamic domain name biguard.billion.com is configured for both WAN1
and WAN2, the active WAN port will announce the domain name through the WAN IP
address. The remote gateway will then be able to connect to the VPN through the
domain name.
In this Gateway to Gateway example, BiGuard 30 is communicating to a remote
gateway using WAN1 through a secure VPN tunnel. Should WAN1 fail, outbound
traffic from BiGuard 30 will automatically be redirected to WAN2. This process is
completely transparent to the remote gateway, as BiGuard 30 will automatically
update the domain name (biguard.billion.com) with the WAN2 IP address.
Configuring a Gateway to Multiple Gateway setup with Fail Over is similar, as shown
below:

The VPN Concentrator provides an easy way for branch offices to connect to
headquarter through a VPN tunnel. All branch office traffic will be redirected to the
VPN tunnel to headquarter with the exception of LAN-side traffic. This way, all
branch offices can connect to each other through headquarter via the headquarter’s
firewall management. You can also configure BiGuard 30 to function as a VPN
Concentrator:

Chapter 3: Getting Started
3.1 Overview
BiGuard 30 is designed to be a powerful and flexible network device that is also easy
to use. With an intuitive web-based configuration, BiGuard 30 allows you to
administer your network via virtually any Java-enabled web browser and is fully
compatible with Linux, Mac OS, and Windows 98/Me/NT/2000/XP operating
systems.
The following chapter takes you through the very first steps to configuring your
network for BiGuard 30. Take a look and see how easy it is to get your network up
and running.
3.2 Before You Begin
BiGuard 30 is a flexible and powerful networking device. To simplify the
configuration process and increase the efficiency of your network, consider the
following items before setting up your network for the first time:
1. Plan your network
Decide whether you are going to use one or both WAN ports. For one WAN port, you
may need a fully qualified domain name either for convenience or if you have a
dynamic IP address. If you are going to use both WAN ports, determine whether you
are going to use them in fail over mode for increased network reliability or load
balancing mode for maximum bandwidth efficiency. See Chapter 2: Router
Applications for more information.
2. Set up your accounts
Have access to the Internet and locate the Internet Service Provider (ISP)
configuration information. Each BiGuard 30 WAN port must be configured separately,
whether you are using a separate ISP for each WAN port or are having the traffic of
both WAN ports routed through the same ISP.
3. Determine your network management approach
BiGuard 30 is capable of remote management. However, this feature is not active by
default. If you reset the device, remote administration must be enabled again. If
you decide to manage your network remotely, be sure to change the default
33
password for security reason.
4. Prepare to physically connect BiGuard 30 to Cable or DSL modems and a
computer.
Be sure to also review the Safety Warnings located in the preface of this manual
before working with your BiGuard 30.
3.3 Connecting Your Router
Connecting BiGuard 30 is an easy three-step process:
1. Connect BiGuard 30 to your LAN by connecting Ethernet cables from your
networked PCs to the LAN ports on the router. Connect BiGuard 30 to your
broadband Internet connection via router’s WAN port.
2. Plug BiGuard 30 to an AC outlet with the included AC Power Adapter.
3. Ensure that the Power and WAN LEDs are solidly lit, and that on any LAN port that
has an Ethernet cable plugged in the LED is also solidly lit. The Status LED will
remain solid as the device boots. Once the boot sequence is complete, the LED will
shut off, indicating that BiGuard 30 is ready.
If the router does not power on, please refer to Chapter 5: Troubleshooting for
possible solutions.
34
3.4 Configuring PCs for TCP/IP Networking
Now that your BiGuard 30 is connected properly to your network, it’s time to
configure your networked PCs for TCP/IP networking.
In order for your networked PCs to communicate with your router, they must have
the following characteristics:
1. Have a properly installed and functioning Ethernet Network Interface Card (NIC).
2. Be connected to BiGuard 30, either directly or through an external repeater hub
via an Ethernet cable.
3. Have TCP/IP installed and configured with an IP address.
The IP address for each PC may be a fixed IP address or one that is obtained from a
DHCP server. If using a fixed IP address, it is important to remember that it must be
in the same subnet as the router. The default IP address of BiGuard 30 is
192.168.1.254 with a subnet mask of 255.255.255.0. Using the default
configuration, networked PCs must reside in the same subnet, and have an IP
address in the range of 192.168.1.1 to 192.168.1.253. However, you’ll find that the
quickest and easiest way to configure the IP addresses for your PCs is to obtain the
IP addresses automatically by using the router as a DHCP server.
If you are unable to access the web configuration interface, check to see if you have
any software-based firewalls installed on your PCs, as they can cause problems
accessing the 192.168.1.254 IP address of BiGuard 30.
The following sections outline how to set up your PCs for TCP/IP networking. Refer
to the applicable section for your PC’s operating system.
3.4.1 Overview
Before you begin, make sure that the TCP/IP protocol and a functioning Ethernet
network adapter is installed on each of your PCs.

components you need to install TCP/IP on your PCs:
- Windows 95/98/Me/NT/2000/XP
35
- Mac OS 7 and later
If you are using Windows 3.1, you must purchase a third-party TCP/IP application
package.

3.6 Information From Your ISP
3.6.1 Protocols
59
Before configuring this device, you have to check with your ISP (Internet Service
Pr ovider) to find out what kind of s ervice is provided such as DHCP, Static IP, PPPoE,
or PPTP. The following table outlines each of these protocols:
Configure this WAN interface to use DHCP client protocol to get an IP
DHCP
address from your ISP automatically. Your ISP provides an IP address to
the router dynamically when logging in.
Configure this WAN interface with a specific IP address. This IP address
Static IP
should be provided by your ISP.
PPPoE (PPP over Ethernet) is known as a dial-up DSL or cable service. It
is designed to integrate the broadband services into the current widely
PPPoE
deployed, easy-to-use, and low-cost dial-up-access networking
infrastructure.
If your ISP provides a PPTP connection, you can use the PPTP protocol
PPTP
to establish a connection to your ISP.

name and password when configuring your BiGuard 30. After the network and
firewall are configured, BiGuard 30 will login automatically, and you will no longer
need to run the login program from your PC.
3.6.2 Configuration Information
If your ISP does not dynamically assign configuration information but instead uses
fixed configurations, you will need the following basic information from your ISP:
- An IP address and subnet mask
- A gateway IP address
- One or more domain name server (DNS) IP addresses
Depending on your ISP, a host name and domain suffix may also be provided. If any
of these items are dynamically supplied by the ISP, your BiGuard 30 will
automatically acquire them.
60
If an ISP technician configured your computer or if you configured it using
instructions provided by your ISP, you need to copy the configuration information
from your PC’s Network TCP/IP Properties window before reconfiguring your
computer for use with BiGuard 30. The following sections describe how you can
