Chapter 1: Introduction
Introduction to your Router
Welcome to the Billion BiPAC 8500/ 8501/ 8520/ 8521 SHDSL Router. Your SHDSL router is an
“all-in-one” unit, combining an SHDSL modem, SHDSL router and Ethernet network switch,
providing everything you need to get the machines on your network connected to the Internet
over your SHDSL broadband connection. With features such as an SHDSL Quick-Start wizard
and DHCP Server, you can be online in no time at all and with minimum fuss and configuration,
catering for both first-time users and professionals who require advanced features to control
their Internet connection and network.
Features
SHDSL Multi-Mode Standard
BiPAC 8500 / 8520 SHDSL supports downstream and upstream transmission rates of up
to 2.3 / 4.6 Mbps, respectively, and BiPAC 8501 SHDSL.bis can support up to 5.7 Mbps
on 2-wire and 8521 SHDSL.bis can support up to 11.4 Mbps on 4-wire. BiPAC 85xx
series also supports rate management that allows SHDSL subscribers to select an
Internet access speed suiting their needs and budgets. BiPAC 8500/ 8520 and 8501/
8521 follows ITU standard PAM16 Line Code complies with G.991.2 and G.994.1
standards, and BiPAC 8501 follows PAM 32 Line code with G.991.2 and G.991.2.bis
standards. These three models can support Annex A and B operating mode.
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between
MDI and MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or crossover
cable can be used directly for auto detection.
Multi-Protocol to establish a connection
It supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516), and IPoA
(RFC1577) to establish a connection with the ISP. The product also supports VC-based
and LLC-based multiplexing.
Quick Installation Wizard
It supports a WEB GUI page to install this device quickly. With this wizard, end users not
only can enter the information they get from their ISP easily, it also enables immediate
internet suffing.
Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone
devices and PCs from many different vendors. It makes networking simple and
affordable for users. UPnP architecture leverages TCP/IP and the Web to enable
seamless proximity networking in addition to controling data transfer among networked
Chapter 1: Introduction
1
Billion BiPAC 8500/8501/8520/8521 SHDSL (VPN) Firewall Bridge/ Router
devices. With this feature enabled, users can now connect to Net meeting or MSN
Messenger seamlessly.
Network Address Translation (NAT)
Allows multi-users to access outside resources such as the Internet simultaneously with
one IP address/one Internet access account. Many application layer gateways (ALG) are
supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping,
NetMeeting, IP phone and others.
SOHO Firewall Security with DoS and SPI
Along with the built-in NAT natural firewall feature, the router also provides advanced
hacker pattern-filtering protection. It can automatically detect and block Denial of Service
(DoS) attacks. The router is built with Stateful Packet Inspection (SPI) to determine if a
data packet is allowed access to the private LAN through the firewall.
Domain Name System (DNS) relay
It provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) and IP address. When a local machine sets its DNS server with this
router IP address, every DNS conversion request packet from the PC to this router will
be forwarded to the real DNS of an outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. For example, to use the service, you
must first apply for an account from a DDNS service like http://www.dyndns.org/. More
than 5 DDNS servers are supported.
Quality of Service (QoS)
QoS gives you full control over which type of outgoing data traffic should be given priority
by the router, ensuring important data like gaming packets, customer information, or
management information move through the router speed fast, even under heavy load.
The QoS features are configurable by source IP address, destination IP address,
protocol, and port. You can throttle the speed of different types of outgoing data passing
through the router to ensure P2P users don’t saturate the upload bandwidth, or office
browsing doesn’t bring client web serving to a halt. Alternatively, you can simply change
the priority of different types of upload data and let the router sort out the actual speeds
of each data transmission.
Virtual Private Network (VPN) (BiPAC 8500/ 8501/ 8520 Only)
It allows user to establish a virtual network with a remote computer. In this way data can
be transmitted securedly through the virtual tunnel formed within the network. User can
use embedded PPTP and L2TP client/server, IKE and IPSec which are supported by this
router to make a VPN connection or run the PPTP client in PC and the router which
provides IPSec and PPTP pass through function to establish a VPN connection if the
user likes to run the PPTP client in his local computer.
Virtual Server (“port forwarding”)
Users can specify some services to be visible from outside users. The router can detect
incoming service requests and forward either a single port or a range of ports to specific
local computer for handling. For example, a user can assign a PC in the LAN acting as a
WEB server inside and expose it to the outside network. Outside users can browse
inside web servers directly while it is protected by NAT. A DMZ host setting is also
provided to a local computer exposed to the outside network, Internet.

Rich Packet Filtering
Not only filters the packet based on IP address, but also based on Port numbers. It will
filter packets from and to the Internet. It also provides a higher level of security control.
Dynamic Host Configuration Protocol (DHCP) client and server
In the WAN site, the DHCP client can get an IP address from the Internet Service
Provider (ISP) automatically. In the LAN site, the DHCP server can allocate a range of
client IP addresses including IP address, subnet mask as well as DNS IP address and
distribute them to local computers. It provides an easy way to manage the local IP
network.
Static and RIP1/2 Routing
It has routing capability and supports easy static routing table or RIP1/2 routing protocol.
Simple Network Management Protocol (SNMP)
It is an easy way to remotely manage the router via SNMP.
Web based GUI
It supports web based GUI for configuration and management. It is user-friendly and
comes with on-line help. It also supports remote management capability for remote users
to configure and manage this product.
Firmware Upgradeable
Device can be upgraded to the latest firmware through the WEB based GUI.
Rich Management Interfaces
It supports flexible management interfaces with local console port, LAN port, and WAN
port. Users can use terminal applications through the console port to configure and
manage the device, or Telnet, WEB GUI, and SNMP through LAN or WAN ports to
configure and manage the device.

Chapter 3: Basic Installation
The router can be configured with your web browser. A web browser is included as a standard
application in the following operating systems: Linux, Mac OS, Windows 98/NT/2000/XP/Me,
etc. The product provides an easy and user-friendly interface for configuration.
Please check your PC’s network components. The TCP/IP protocol stack and Ethernet network
adapter must be installed. If not, please refer to your Windows-related or other operating
system manuals.
There are ways to connect to the router, either through an external repeater hub to the router or
directly connecting with PCs. However, to be sure PCs have an Ethernet interface installed
properly prior to connecting to the router. You ought to configure your PCs to obtain an IP
address through a DHCP server or a fixed IP address that must be in the same subnet as the
router. The default IP address of the router is 192.168.1.254 and the subnet mask is
255.255.255.0 (i.e. any attached PC must be in the same subnet, and have an IP address in the
range of 192.168.1.1 to 192.168.1.253). The best and easiest way is to configure the PC to get
an IP address automatically from the router using DHCP. If you encounter any problem
accessing the router’s web interface it may also be advisable to uninstall any kind of software
firewall on your PCs, as they can cause problems accessing the 192.168.1.254 IP address of
the router. Users should make their own decisions on how to best protect their network.
Please follow the steps below for your PC’s network environment installation.
Any TCP/IP capable workstation can be used to communicate with or
through the SHDSL Router. To configure other types of workstations, please
consult the manufacturer’s documentation.
Connecting your router
1. Connect the Router to a LAN (Local Area Network) and the SHDSL LINE.

Port Setting
This section allows you to configure the settings for the router’s Ethernet ports to solve some of
the compatibility problems that may be encountered while connecting to the Internet, as well
allowing users to tweak the performance of their network.
• Port # Connection Type: Six options to choose from: Auto, 10M half-duplex, 10M full-
duplex, 100M half-duplex, 100M full-duplex and Disable. Sometimes, there are Ethernet
compatibility problems with legacy Ethernet devices, and you can configure different
types to solve compatibility issues. The default is Auto, which users should keep unless
there are specific problems with PCs not being able to access your LAN.

• IPv4 TOS priority Control (Advanced users): TOS, Type of Services, is the 2
an IP packet. Bits 6-7 of this octet are reserved and bit 0-5 are used to specify the priority
of the packet.
This feature uses bits 0-5 to classify the packet’s priority. If the packet is high priority, it
will flow first and will not be constrained by the Rate Limit. Therefore, when this feature is
enabled, the router’s Ethernet switch will check the 2

DHCP Server
You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or enable
the router’s DHCP relay functions. The DHCP protocol allows your router to dynamically assign
IP addresses to PCs on your network if they are configured to obtain IP addresses automatically.
To disable the router’s DHCP Server, check Disabled and click Next, then click Apply. When
the DHCP Server is disabled you will need to manually assign a fixed IP address to each PCs
on your network, and set the default gateway for each PCs to the IP address of the router (by
default this is 192.168.1.254).
To configure the router’s DHCP Server, check DHCP Server and click Next. You can then
configure parameters of the DHCP Server including the IP pool (starting IP address and ending
IP address to be allocated to PCs on your network), lease time for each assigned IP address
(the period of time the IP address assigned will be valid), DNS IP address and the gateway IP
address. These details are sent to the DHCP client (i.e. your PC) when it requests an IP
address from the DHCP server. Click Apply to enable this function. If you check “Use Router
as a DNS Server”, the Router will perform the domain name lookup, find the IP address from
the network outside your network automatically and forward it back to the requesting PC in the
LAN (your Local Area Network).

DNS
A Domain Name System (DNS) contains a mapping table for domain name and IP addresses.
On the Internet, every host has a unique and user-friendly name (domain name) such as
www.helloworld.com and an IP address. An IP address is a 32-bit number in the form of
xxx.xxx.xxx.xxx, for example 192.168.1.254. You can think of an IP address as a telephone
number for devices on the Internet, and the DNS will allow you to find the telephone number for
any particular domain name. As an IP Address is hard to remember, the DNS converts the
friendly name into its equivalent IP Address.
You can obtain a Domain Name System (DNS) IP address automatically if your ISP has
provided it when you logon, check the Enable box. Usually when you choose PPPoE or PPPoA
as your WAN - ISP protocol, the ISP will provide the DNS IP address automatically. You may
leave the configuration field blank.
Alternatively, your ISP may provide you with an IP address of their DNS. If this is the case, you
must enter the DNS IP address manually.
If you choose one of the other three protocols ─ RFC1483 Routed/Bridged and IPoA, check
with your ISP as it may provide you with an IP address for their DNS server. You must enter the
DNS IP address if you set the DNS of your PC to the LAN IP address of this router.

Time Zone
The router does not have a real time clock on board; instead, it uses the Simple Network Time
Protocol (SNTP) to get the current time from an SNTP server outside your network. Choose
your local time zone, click Enable and click the Apply button. After a successful connection to

• Daylight Saving is also known as Summer Time Period. Many places in the world
adapt it during summer time to move one hour of daylight from morning to the evening in
local standard time. Check Automatic box to auto set your local time.
• Resync Period (in minutes) is the periodic interval the router will wait before it re-
synchronizes the router’s time with that of the specified SNTP server. In order to avoid
unnecessary increase of the load on your specified SNTP server you should keep the
poll interval as high as possible – at the absolute minimum every few hours or even days.

Firmware Upgrade
Your router’s “firmware” is the software that allows it to operate and provides all its functionality.
Think of your router as a dedicated computer, and the firmware as the software it runs. Over
time this software may be improved and modified, and your router allows you to upgrade the
software it runs to take on advantage of these changes.
Clicking on Browse will allow you to select the new firmware image file you have downloaded
to your PC. Once the correct file is selected, click Upgrade to update the firmware in your router.
DO NOT power down the router or interrupt the firmware upgrading
while it is still in process. Improper operation could damage the router.

advisable to backup your router’s settings before making any significant changes to your
router’s configuration.
Press Backup to select where on your local PC you want to save the setting file. You may also
change the name of the file when saving if you wish to keep multiple backups.
Press Browse to select a file from your PC to restore. You should only restore settings files that

Firewall and Access Control
Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet access
from your LAN, as well as helping to prevent attacks from hackers. In addition to this, when
using NAT, the router acts as a “natural” Internet firewall, as all PCs on your LAN will use private
IP addresses that cannot be directly accessed from the Internet.
• Firewall: Prevents access from outside your network. The router provides three levels of
security support:
• NAT natural firewall: This masks LAN users’ IP addresses which is invisible to outside
users on the Internet, making it much more difficult for a hacker to target a machine on
your network. This natural firewall is on when NAT function is enabled.
When using Virtual Servers, your PCs will be exposed at a certain degree
specified in your Virtual Server settings when the ports specified are
opened in your firewall packet filter settings.

General Settings
You can choose not to enable Firewall, you will not able to add filter rules by yourself in the
Packet Filter, or enable the Firewall using preset filter rules and modify the packet filter rules as
required. The Packet Filter is used to filter packets based-on Applications (Port) or IP addresses.
There are four options to choose when you enable Firewall, these are:
• All blocked/User-defined: no pre-defined port or address filter rules by default, meaning
that all inbound (Internet to LAN) and outbound (LAN to Internet) packets will be blocked.
Users have to add their own filter rules for further access to the Internet.
• High/Medium/Low security level: the predefined port filter rules for High, Medium and
Low security are displayed in Port Filters of the Packet Filter.
Select either High, Medium or Low security level to enable Firewall. The only difference
between these three security levels is the preset port filter rules in the Packet Filter. Firewall
functionality is the same for all levels; it is only the list of preset port filters that changes
between each setting. For more detailed on level of preset port filter information, refer to Table
1: Predefined Port Filter.
Note: The changes or added custom filters on a previous security level will be remembered
whenever newer security level is selected. There is no need to reconfigure all settings again if
switching back to the previous level.
The “Block WAN Request” is a stand-alone function and is not affected by whether security is
enabled or disabled. Mostly this is for preventing any scan tools from the hacker from WAN site.
Any remote user who is attempting to perform this action may result in
blocking all the access to configure and management of the device from
the Internet.

Example: Configuring your firewall to allow for a publicly accessible web server on your
LAN
The predefined port filter rule for HTTP (TCP port 80) is the same whether the firewall is set to a
high, medium or low security level. To setup a web server located on the local network when the
firewall is enabled, you have to configure the Port Filters setting for HTTP.
As you can see from the diagram below, when the firewall is enabled with one of the three
presets (Low/Medium/High), inbound HTTP access is not allowed which means remote access
through HTTP to your router is not allowed.
Note: Inbound indicates accessing from Internet to LAN and Outbound is from LAN to the
Internet

Intrusion Detection
The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and intrusion
attempts from the Internet. If the IDS function of the firewall is enabled, inbound packets are
filtered and blocked depending on whether they are detected as possible hacker attacks,
intrusion attempts or other connections that the router determines to be suspicious.
Blacklist: If the router detects a possible attack, the source IP or destination IP address will be
added to the Blacklist. Any further attempts using this IP address will be blocked for the time
period specified as the Block Duration. The default setting for this function is false (disabled).
Some attack types are denied immediately without using the Blacklist function, such as Land
attack and Echo/CharGen scan.
• Intrusion Detection: If enabled, IDS will block Smurf attack attempts. Default is false.
• Block Duration:
o Victim Protection Block Duration: This is the duration for blocking Smurf attacks.
Default value is 600 seconds.
o Scan Attack Block Duration: This is the duration for blocking hosts that attempt
a possible Scan attack. Scan attack types include X’mas scan, IMAP SYN/FIN
scan and similar attempts. Default value is 86400 seconds.
o DOS Attack Block Duration: This is the duration for blocking hosts that attempt a
possible Denial of Service (DoS) attack. Possible DoS attacks this attempts to
block include Ascend Kill and WinNuke. Default value is 1800 seconds.
• Max TCP Open Handshaking Count: This is a threshold value to decide whether a
SYN Flood attempt is occurring or not. Default value is 100 TCP SYN per seconds.
• Max PING Count: This is a threshold value to decide whether an ICMP Echo Storm is
occurring or not. Default value is 15 ICMP Echo Requests (PING) per second.
• Max ICMP Count: This is a threshold to decide whether an ICMP flood is occurring or
not. Default value is 100 ICMP packets per seconds except ICMP Echo Requests

URL Filtering
URL (Uniform Resource Locator – e.g. an address in the form of http://www.abcde.com or
http://www.example.com) filter rules allow you to prevent users on your network from accessing
particular websites by their URL. There are no pre-defined URL filter rules; you can add filter
rules to meet your requirements.
• Enable/Disable: To enable or disable URL Filter feature.
• Block Mode: A list of modes that you can choose from to check the URL filter rules.
o Disabled: No action will be performed by the Block Mode.
o Always On: Action is enabled. URL filter rules will be monitoring and checking at
all hours of the day.
o TimeSlot1 ~ TimeSlot16: It is self-defined time period. You may specify the time
period to check the URL filter rules, i.e. during working hours. For setup and detail,
refer to Time Schedule section.
• Keywords Filtering: Allow blocking by specific keywords within a particular URL rather
than having to specify a complete URL (e.g. to block any image called
“advertisement.gif”). When enabled, your specified keywords list will be checked to see if
any keywords are present in URLs accessed to determine if the connection attempt
should be blocked. Please note that the URL filter blocks web browser (HTTP)
connection attempts using port 80 only.
For example, if the URL is http://www.abc.com/abcde.html, it will be dropped if the keyword
“abcde” occurs in the URL.
• Domains Filtering: This function checks the whole URL accessed and not just the IP
address in URLs against your list of domains to block or to allow. If it is matched, the
URL request will be sent (Trusted) or dropped (Forbidden). For this function to be
activated, both check-boxes must be checked. Below is the checking procedure:
1. Check the domain in the URL to determine if it is in the trusted list. If yes, the connection
attempt is sent to the remote web server.
2. If not, check if it is listed in the forbidden list. If yes, then the connection attempt will be
93
Chapter 4: Configuration
Billion BiPAC 8500/8501/8520/8521 SHDSL (VPN) Firewall Bridge/ Router
dropped.
3. If the packet does not match either of the above two items, it is sent to the remote web server.
4. Please be noted that the completed URL, “www” + domain name, shall be specified. For
example to block traffic to www.google.com.au, enter “www.google” or “www.google.com”
In the example below, the URL request for www.abc.com will be sent to the remote web server
because it is listed in the trusted list, whilst the URL request for www.google or www.google.com
will be dropped, because www.google is in the forbidden list.
Example: Andy wishes to disable all WEB traffic except for the ones listed in the trusted
domain list, which would prevent Bobby from accessing other web sites. Andy selects both
functions in the Domain Filtering and thinks that it will stop Bobby. Nevertheless, Bobby knows
that Domain Filtering will ONLY disable all WEB traffic except for the one in the Trusted
Domain, BUT not its IP address. If this is the situation, Block surfing by IP address function
can be handy and helpful to Andy. With this feature, Andy can prevent Bobby from accessing
unwanted websites.
• Restrict URL Features: This function enhances the restriction to your URL rules.
o Block Java Applet: This function can block Web content that includes the Java
Applet. It is to prevent someone who wants to damage your system via standard
HTTP protocol.
o Block surfing by IP address: Preventing someone who uses the IP address as
URL for skipping Domains Filtering function. Activate only and if Domain Filtering
is enabled.

IM / P2P Blocking
IM, short for Instant Message, is required to use client program software that allows users to
communicate, in exchanging text message, with other IM users in real time over the Internet. A
P2P application, known as Peer-to-peer, is a group of computer users who share files with
specific groups of people across the Internet. Both Instant Message and Peer-to-peer
applications make communication faster and easier but your network can become increasingly
insecure at the same time. Billion’s IM and P2P blocking helps to restrict LAN PCs from
accessing the commonly used IM such as Yahoo and MSN, and P2P, BitTorrent and eDonkey
applications over the Internet.
• Instant Message Blocking: The default is set to Disabled.
o Disabled: Instant Message blocking is not triggered. No action will be performed.
o Always On: Action is enabled.
o TimeSlot1 ~ TimeSlot16: This is the self-defined time period. You may specify
the time period to trigger the blocking, i.e. during working hours. For setup and
detail, refer to Time Schedule section.
• Yahoo/MSN Messenger: Check the box to block either or both Yahoo or/and MSN
Messenger. Be sure you enabled the Instant Message Blocking first.
• Peer to Peer Blocking: The default is set to Disabled.
o Disabled: Instant Message blocking is not triggered. No action will be performed.
o Always On: Action is enabled.
o TimeSlot1 ~ TimeSlot16: This is the self-defined time period. You may specify
the time period to trigger the blocking, i.e. during working hours. For setup and
detail, refer to Time Schedule section.
• BitTorrent / eDonkey: Check the box to block either or both Bit Torrent or/and eDonkey.
Be sure you enabled the Peer to Peer Blocking first.
