Chapter 1: Introduction  
Introduction to your Router  
Welcome to the Billion BiPAC 8500/8501/8520 SHDSL Router. Your Billion 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 a minimum of fuss and configuration, catering for first-time users to the  
guru requiring advanced features and control over 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. 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 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 can enter the  
information easily which they get from their ISP, then surf the Internet immediately.  
Universal Plug and Play (UPnP) and UPnP NAT Traversal  
This protocol is used to enable simple and robust connectivity among stand-alone devices  
PCs from many different vendors. It makes network simple and affordable for users. UPnP  
and  
architecture leverages TCP/IP and the Web to enable seamless proximity networking in addition to  
control and data transfer among networked 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 gateway (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  
through the firewall to the private LAN.

SHDSL VPN Firewall Bridge/Router  
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’s IP  
address, every DNS conversion request packet from the PC to this router will be forwarded to the  
real DNS in the 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 types 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 ay lightning speed, even under  
heavy load. The QoS features are configurable by source IP address, destination IP address,  
protocol, and port. You can throttle the speed at which different types of outgoing data pass through  
the router, to ensure P2P users don’t saturate upload bandwidth, or office browsing doesn’t bring  
client web serving to a halt. In addition, or alternatively, you can simply change the priority of  
different types of upload data and let the router sort out the actual speeds.  
Virtual Private Network (VPN)  
It allows user to make a tunnel with a remote site directly to secure the data transmission among  
the connection. User can use embedded PPTP and L2TP client/server, IKE and IPSec which are  
supported by this router to make a VPN connection or users can run the PPTP client in PC and the  
router already 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 the specific local computer to  
handle it. 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, and 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 and  
distribute them including IP address, subnet mask as well as DNS IP address 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.

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 with 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 device. 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 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 2nd octet of 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 2nd octet of each IP packet. If the value in the TOS field matches the checked values  
in the table (0 to 63), this packet will be treated as high priority.

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 outside network automatically and forward it back to the  
requesting PC in the LAN (your Local Area Network).  
If you check DHCP Relay Agent and click Next, then you will have to enter the IP address of the DHCP  
server which will assign an IP address back to the DHCP client in the LAN. Use this function only if  
advised to do so by your network administrator or ISP.  
Click Apply to enable this function.

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,  
it may provide you with an IP address for their DNS server. You must enter the DNS IP address if you set

System  
Here are items within the System section: Time Zone, Remote Access, Firmware Upgrade,  
Backup/Restore, Restart and User Management.  
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 successful connection to the Internet, the router will retrieve  
the correct local time from the SNTP server you have specified. If you prefer to specify an SNTP server  
other than those in the list, simply enter its IP address as shown above. Your ISP may provide an SNTP  
server for you to use.  
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 unnecessarily increasing 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  
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.

Backup / Restore  
These functions allow you to save and backup your router’s current settings to a file on your PC, or to  
restore a previously saved backup. This is useful if you wish to experiment with different settings,  
knowing that you have a backup handy in the case of any mistakes. It is 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 to save the settings 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 have  
been generated by the Backup function, and that were created when using the current version of the  
router’s firmware. Settings files saved to your PC should not be manually edited in any way.  
After selecting the settings file you wish to use, pressing Restore will load those settings into the router.

User Management  
In order to prevent unauthorized access to your router’s configuration interface, it requires all users to  
login with a password. You can set up multiple user accounts, each with their own password.  
You are able to Edit existing users and Create new users who are able to access the device’s  
configuration interface. Once you have clicked on Edit, you are shown the following options:  
You can change the user’s password, whether their account is active and Valid, as well as add a  
comment to each user account. These options are the same when creating a user account, with the  
exception that once created you cannot change the username. You cannot delete the default admin  
account; however, you can delete any other created accounts by clicking Delete when editing the user.  
You are strongly advised to change the password on the default “admin” account when you receive your  
router, and any time you reset your configuration to Factory Defaults.

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 to the degree  
specified in your Virtual Server settings provided the ports specified are  
opened in your firewall packet filter settings.  
Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules to prevent  
unauthorized computers or applications accessing your local network from the Internet.  
Intrusion Detection: Enable Intrusion Detection to detect, prevent and log malicious attacks.  
Access Control: Prevents access from PCs on your local network:  
Firewall Security and Policy (General Settings): Outbound direction of Packet Filter rules to prevent  
unauthorized computers or applications accessing the Internet.  
URL Filter: To block PCs on your local network from unwanted websites.  
Here are items under the Firewall section: General Settings, Packet Filter, Intrusion Detection, URL

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 when you enable the Firewall, they 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 Packet Filter.  
Select either High, Medium or Low security level to enable the 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 not relate to whether security enable or disable.  
Mostly it is for preventing any scan tools from WAN site by hacker.  
Any remote user who is attempting to perform this action may result in  
blocking all the accesses to configure and manage of the device from the  
Internet.

The predefined port filter rule for HTTP (TCP port 80) is the same no matter 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.

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:  
Victim Protection Block Duration: This is the duration for blocking Smurf attacks. Default  
value is 600 seconds.  
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.  
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 (PING).  
For SYN Flood, ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event Log. It cannot  
protect against such attacks.

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: Allows 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 as the keyword “abcde”  
occurs in the URL.  
Domains Filtering: This function checks the whole URL not the IP address, in URLs accessed against  
your list of domains to block or 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. Here 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  
dropped.

If the packet does not match either of the above two items, it is sent to the remote web  
server.  
Please be note that the completed URL, “www” + domain name, shall be specified. For  
example to block traffic to www.google.com.au, enter “www.google” or  
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 ones listed in the trusted domain, which  
would prevent Bobby from accessing other web sites. Andy selects both functions in the Domain  
Filtering and thinks that it will stop Bobby. But Bobby knows this function, Domain Filtering, ONLY  
disables all WEB traffic except for 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. Now, Andy can prevent Bobby  
from accessing other sites.  
Restrict URL Features: This function enhances the restriction to your URL rules.  
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.  
Block surfing by IP address: Preventing someone who uses the IP address as URL for skipping  
Domains Filtering function. Activates only and if Domain Filtering 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 group of computer users who share file to 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 users to restrict LAN PCs to access to the commonly used IM, Yahoo and MSN, and P2P,  
BitTorrent and eDonkey, applications over the Internet.

VPN - Virtual Private Networks  
Virtual Private Networks is ways to establish secured communication tunnels to an organization’s network  
via the Internet. Your router supports three main types of VPN (Virtual Private Network), PPTP, IPSec  
and L2TP.  
PPTP (Point-to-Point Tunneling Protocol)  
There are two types of PPTP VPN supported; Remote Access and LAN-to-LAN (please refer below for  
more information.). Click Create to configure a new VPN connection.  
After you have created PPTP connection, account status will be displayed. (See example above).  
Enable / Disable: This function activates or deactivates the PPTP connection. To wish interrupting  
the tunnel, check Disable radio button and click Apply button to deactivate the connection.  
Name: User-defined name of the connection.  
Type: This refers to your router operates as a client or a server, Dialout or Dialin in respectively.  
Status: It informs your PPTP tunnel connection condition.

SHDSL VPN Firewall Bridge/Router  
PPTP Connection - Remote Access  
Connection Name: User-defined name for the connection (e.g. “connection to office”).  
Type: Check Dial Out if you want your router to operate as a client (connecting to a remote VPN server,  
e.g. your office server), check Dial In operates as a VPN server.  
When configuring your router as a Client, enter the remote Server IP Address (or Domain  
Name) you wish to connection to.  
When configuring your router as a server, enter the Private IP Address Assigned to Dial in  
User address.  
Username: If you are a Dial-Out user (client), enter the username provided by your Host. If you are a  
Dial-In user (server), enter your own username.  
Password: If you are a Dial-Out user (client), enter the password provided by your Host. If you are a  
Dial-In user (server), enter your own password.  
PPP Authentication Type: Default is Auto if you want the router to determine the authentication type to  
use, or else manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP (Password  
Authentication Protocol) if you know which type the server is using (when acting as a client), or else the  
authentication type you want clients connecting to you to use (when acting as a server). When using PAP,  
the password is sent unencrypted, whilst CHAP encrypts the password before sending, and also allows  
for challenges at different periods to ensure that an intruder has not replaced the client.  
Data Encryption: Data sent over the VPN connection can be encrypted by an MPPE algorithm. Default  
is Auto, so that this setting is negotiated when establishing a connection, or else you can manually  
Enable or Disable encryption.  
Key Length: The data can be encrypted by MPPE algorithm with 40 bits or 128 bits. Default is Auto, it is  
negotiated when establishing a connection. 128 bit keys provide stronger encryption than 40 bit keys.  
Mode: You may select Stateful or Stateless mode. The key will be changed every 256 packets when you  
select Stateful mode. If you select Stateless mode, the key will be changed in each packet.  
Idle Time: Auto-disconnect the VPN connection when there is no activity on the connection for a  
predetermined period of time. 0 means this connection is always on.  
Active as default route: Commonly used by the Dial-out connection which all packets will route through  
the VPN tunnel to the Internet; therefore, active the function may degrade the Internet performance.

IPSec VPN Connection  
Connection Name: User-defined name for the connection (e.g. “connection to office”).  
Local Network: Set the IP address, subnet or address range of the local network.  
Single Address: The IP address of the local host.  
Subnet: The subnet of the local network. For example, IP: 192.168.1.0 with netmask  
255.255.255.0 specifies one class C subnet starting from 192.168.1.1 (i.e. 192.168.1.1 through to  
192.168.1.254).  
IP Range: The IP address range of the local network. For example, IP: 192.168.1.1, end IP:  
192.168.1.10.  
Remote Secure Gateway Address (or Domain Name): The IP address or hostname of the remote VPN  
device that is connected and establishes a VPN tunnel.  
Remote Network: Set the IP address, subnet or address range of the remote network.  
Proposal: Select the IPSec security method. There are two methods of checking the authentication  
information, AH (authentication header) and ESP (Encapsulating Security Payload). Use ESP for greater  
security so that data will be encrypted and authenticated. Using AH data will be authenticated but not  
encrypted.  
Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered  
with in transmit. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm (SHA1) or  
NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower.  
MD5: A one-way hashing algorithm that produces a 128bit hash.  
SHA1: A one-way hashing algorithm that produces a 160bit hash.  
Encryption: Select the encryption method from the pull-down menu. There are several options, DES,  
3DES, AES (128, 192 and 256) and NULL. NULL means it is a tunnel only with no encryption. 3DES and  
AES are more powerful but increase latency.  
DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method.

AES: Stands for Advanced Encryption Standards, you can use 128, 192 or 256 bits as  
encryption method.  
Perfect Forward Secrecy: Choose whether to enable PFS using Diffie-Hellman public-key cryptography  
to change encryption keys during the second phase of VPN negotiation. This function will provide better  
security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that  
allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the  
Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for  
Modular Exponentiation Groups.  
Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters.  
Both sides should use the same key. IKE is used to establish a shared security policy and authenticated  
keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router  
must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key  
into both sides (router or hosts).

SA Lifetime: Specify the number of minutes that a Security Association (SA) will stay active before new  
encryption and authentication key will be exchanged. There are two kinds of SAs, IKE and IPSec. IKE  
negotiates and establishes SA on behalf of IPSec, an IKE SA is used by IKE.  
Phase 1 (IKE): To issue an initial connection request for a new VPN tunnel. The range can be  
from 5 to 15,000 minutes, and the default is 480 minutes.  
Phase 2 (IPSec): To negotiate and establish secure authentication. The range can be from 5 to  
15,000 minutes, and the default is 60 minutes.  
A short SA time increases security by forcing the two parties to update the keys. However, every  
time the VPN tunnel re-negotiates, access through the tunnel will be temporarily disconnected.  
Ping to Keep Alive:  
PING to the IP: It is able to IP Ping the remote PC with the specified IP address and alert when the  
connection fails. Once alter message is received, Router will drop this tunnel connection. Re-establish  
of this connection is required. Default setting is 0.0.0.0 which disables the function.  
Interval: This sets the time interval between Pings to the IP function to monitor the connection status.  
Default interval setting is 10 seconds. Time interval can be set from 0 to 3600 second, 0 second  
disables the function.

SHDSL VPN Firewall Bridge/Router  
L2TP (Layer Two Tunneling Protocol)  
Two types of L2TP VPN are supported Remote Access and LAN-to-LAN (please refer below for more  
information.). Click Create to create a new VPN connection account.  
After you have created L2TP connection, account status will be displayed. (See example above).  
Enable / Disable: This function activates or deactivates the L2TP connection. To wish interrupting  
the tunnel, check Disable radio button and click Apply button to deactivate the connection.  
Name: This is the user-defined name of the connection.  
Type: This refers to your router operates as a client or a server, Dialout or Dialin in respectively.  
Status: It informs your L2TP tunnel connection condition.

L2TP Connection - Remote Access  
L2TP VPN Connection  
Connection Name: User-defined name for the connection (e.g. “connection to office”).  
Type: Check Dial Out if you want your router to operate as a client (connecting to a remote VPN server,  
e.g. your office server), check Dial In operates as a VPN server.  
When configuring your router as a Client, enter the remote Server IP Address (or  
Hostname)  
you wish to connection to.  
When configuring your router as a server, enter the Private IP Address Assigned to Dial in  
User address.  
Username: If you are a Dial-Out user (client), enter the username provided by your Host. If you are a  
Dial-In user (server), enter your own username.  
Password: If you are a Dial-Out user (client), enter the password provided by your Host. If you are a  
Dial-In user (server), enter your own password.  
PPP Authentication Type: Default is Auto if you want the router to determine the authentication type to  
use, or else manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP (Password  
Authentication Protocol) if you know which type the server is using (when acting as a client), or else the  
authentication type you want clients connecting to you to use (when acting as a server). When using PAP,  
the password is sent unencrypted, whilst CHAP encrypts the password before sending, and also allows  
for challenges at different periods to ensure that the client has not been replaced by an intruder.  
Idle Time: Auto-disconnect the VPN connection when there is no activity on the connection for a  
pre-determined period of time. 0 means this connection is always on.  
Active as default route: Commonly used by the Dial-out connection which all packets will route through  
the VPN tunnel to the Internet; therefore, active the function may degrade the Internet performance.

L2TP over IPSec (L2TP/IPSec) VPN Connection  
IPSec: Enable for enhancing your L2TP VPN security.  
Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered  
with in transmit. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm (SHA1) or  
NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower.  
MD5: A one-way hashing algorithm that produces a 128bit hash.  
SHA1: A one-way hashing algorithm that produces a 160bit hash.  
Encryption: Select the encryption method from the pull-down menu. There are four options, DES, 3DES,  
AES and NONE. NONE means it is a tunnel only with no encryption. 3DES and AES are more powerful  
but increase latency.  
DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method.  
3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption  
method.  
AES: Stands for Advanced Encryption Standards, it uses 128 bits as an encryption method.  
Perfect Forward Secrecy: Choose whether to enable PFS using Diffie-Hellman public-key cryptography  
to change encryption keys during the second phase of VPN negotiation. This function will provide better  
security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that  
allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the  
Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for  
Modular Exponentiation Groups.  
Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters.  
Both sides should use the same key. IKE is used to establish a shared security policy and authenticated  
keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router  
must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key  
into both sides (router or hosts).  
Remote Host Name (Optional): Enter hostname of remote VPN device. It is a tunnel identifier from the  
Remote VPN device matches with the Remote hostname provided. If remote hostname matches, tunnel  
will be connected; otherwise, it will be dropped.  
Cautious: This is only when the router performs as a VPN server. This option should be used by  
advanced users only.  
Local Host Name (Optional): Enter hostname of Local VPN device that is connected / establishes a  
VPN tunnel. As default, Router’s default Hostname is home.gateway.  
Tunnel Authentication: This enables router to authenticate both the L2TP remote and L2TP host. This  
is only valid when L2TP remote supports this feature.  
Secret: The secure password length should be 16 characters which may include numbers and  
characters.

Mission-critical application  
Mostly the VPN connection is mission-critical application for doing data exchange between head and  
branch office.  
The mission-critical application must be sent out smoothly without any dropping. Set priority as high level  
for preventing any other applications to saturate the bandwidth.  
Voice application  
Voice is latency-sensitive application. Most VoIP devices are use SIP protocol and the port number will be  
assigned by SIP module automatically. Better to use fixed IP address for catching VoIP packets as high  
priority.  
Above settings will help to improve quality of your VoIP service when traffic is full loading.  
Restricted Application  
Some of companies will setup FTP server for customer downloading or home user sharing their files by  
using FTP.  
With above settings that help to limit utilization of upstream of FTP. Time schedule also help you to only  
limit utilization at daytime.

Virtual Server (“Port Forwarding”)  
In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program (usually  
a server) incoming connections should be delivered to. Some ports have numbers that are pre-assigned  
to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known  
ports”. Servers follow the well-known port assignments so clients can locate them.  
If you wish to run a server on your network that can be accessed from the WAN (i.e. from other machines  
on the Internet that are outside your local network), or any application that can accept incoming  
connections (e.g. Peer-to-peer/P2P software such as instant messaging applications and P2P file-sharing  
applications) and are using NAT (Network Address Translation), then you will usually need to configure  
your router to forward these incoming connection attempts using specific ports to the PC on your network  
running the application. You will also need to use port forwarding if you want to host an online game  
server.  
The reason for this is that when using NAT, your publicly accessible IP address will be used by and point  
to your router, which then needs to deliver all traffic to the private IP addresses used by your PCs. Please  
see the WAN configuration section of this manual for more information on NAT.  
The device can be configured as a virtual server so that remote users accessing services such as Web or  
FTP services via the public (WAN) IP address can be automatically redirected to local servers in the LAN  
network. Depending on the requested service (TCP/UDP port number), the device redirects the external  
service request to the appropriate server within the LAN network

Add Virtual Server  
Because NAT can act as a “natural” Internet firewall, your router protects your network from being  
accessed by outside users when using NAT, as all incoming connection attempts will point to your router  
unless you specifically create Virtual Server entries to forward those ports to a PC on your network.  
When your router needs to allow outside users to access internal servers, e.g. a web server, FTP server,  
Email server or game server, the router can act as a “virtual server”. You can set up a local server with a  
specific port number for the service to use, e.g. web/HTTP (port 80), FTP (port 21), Telnet (port 23),  
SMTP (port 25), or POP3 (port 110), When an incoming access request to the router for a specified port is  
received, it will be forwarded to the corresponding internal server.  
Time Schedule: A self-defined time period to enable your virtual server. You may specify a time  
schedule or Always on for the usage of this Virtual Server Entry. For setup and detail, refer to Time  
Schedule section

Protocol: It is the supported protocol for the virtual server. In addition to specifying the port number to be  
used, you will also need to specify the protocol used. The protocol used is determined by the particular  
application. Most applications will use TCP or UDP.  
External Port: The Port number on the Remote/WAN side used when accessing the virtual server.  
Redirect Port: The Port number used by the Local server in the LAN network.

Example:  
If you like to remote accessing your Router through the Web/HTTP at all time, you would need to enable  
port number 80 (Web/HTTP) and map to Router’s IP Address. Then all incoming HTTP requests from  
you (Remote side) will be forwarded to the Router with IP address of 192.168.1.254. Since port number  
80 has already been predefined, next to the Application click Helper. A list of predefined rules window  
will pop and select HTTP_Sever.  
Application: HTTP_Sever  
Time Schedule: Always On  
Protocol: tcp  
External Port: 80-80  
Redirect Port: 80-80  
IP Address: 192.168.1.254  
Edit: Click it to edit this virtual server application.  
Delete: Click it to delete this virtual server application.  
Using port forwarding does have security implications, as outside users will be  
able to connect to PCs on your network. For this reason you are advised to use  
specific Virtual Server entries just for the ports your application requires,  
instead of using DMZ. As doing so will result in all connections from the WAN  
attempt to access to your public IP of the DMZ PC specified.  
If you have disabled the NAT option in the WAN-ISP section, the Virtual Server  
function will hence be invalid.  
If the DHCP server option is enabled, you have to be very careful in assigning  
the IP addresses of the virtual servers in order to avoid conflicts. The easiest  
way of configuring Virtual Servers is to manually assign static IP address to  
Attention  
each virtual server PC, with an address that does not fall into the range of IP  
addresses that are to be issued by the DHCP server. You can configure the  
virtual server IP address manually, but it must still be in the same subnet as the  
router.

Dynamic DNS  
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users  
whose ISP does not assign them a static IP address to use a domain name. This is especially useful for  
hosting servers via your SHDSL connection, so that anyone wishing to connect to you may use your  
domain name, rather than having to use your dynamic IP address, which changes from time to time. This  
dynamic IP address is the WAN IP address of the router, which is assigned to you by your ISP.  
You will first need to register and establish an account with the Dynamic DNS provider using their website,  
for example http://www.dyndns.org/  
There are more than 5 DDNS services supported.  
Disable: Check to disable the Dynamic DNS function.  
Enable: Check to enable the Dynamic DNS function. The following fields will be activated and  
required:  
Dynamic DNS Server: Select the DDNS service you have established an account with.  
Domain Name, Username and Password: Enter your registered domain name and your username and  
password for this service.  
Period: Set the time period between updates, for the Router to exchange information with the DDNS  
server. In addition to updating periodically as per your settings, the router will perform an update when  
your dynamic IP address changes.

Device Management  
The Device Management advanced configuration settings allow you to control your router’s security  
options and device monitoring features.  
Embedded Web Server ( 2 Management IP accounts)  
HTTP Port: This is the port number the router’s embedded web server (for web-based configuration) will  
use. The default value is the standard HTTP port, 80. Users may specify an alternative if, for example,  
they are running a web server on a PC within their LAN.  
Management IP Address: You may specify an IP address allowed to logon and access the router’s web  
server. Setting the IP address to 0.0.0.0 will disable IP address restrictions, allowing users to login from  
any IP address.  
Expire to auto-logout: Specify a time frame for the system to auto-logout the user’s configuration  
session.  
For Example: User A changes HTTP port number to 100, specifies their own IP address of 192.168.1.55,  
and sets the logout time to be 100 seconds. The router will only allow User A access from the IP  
address 192.168.1.55 to logon to the Web GUI by typing: http://192.168.1.254:100 in their web browser.

After 100 seconds, the device will automatically logout User A.  
Universal Plug and Play (UPnP)  
UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and  
data transfer between devices. UPnP offers many advantages for users running NAT routers through  
UPnP NAT Traversal, and on supported systems makes tasks such as port forwarding much easier by  
letting the application control the required settings, removing the need for the user to control advanced  
configuration of their device.  
Both the user’s Operating System and the relevant application must support UPnP in addition to the  
router. Windows XP and Windows Me natively support UPnP (when the component is installed), and  
Windows 98 users may install the Internet Connection Sharing client from Windows XP in order to  
support UPnP. Windows 2000 does not support UPnP.  
Disable: Check to disable the router’s UPnP functionality.  
Enable: Check to enable the router’s UPnP functionality.  
UPnP Port: Its default setting is 2800. It is highly recommended for users to use this port value. If this  
value conflicts with other ports already being used you may wish to change the port.  
SNMP Access Control (Software on a PC within the LAN is required in order to utilize this function) –  
Simple Network Management Protocol.  
SNMP V1 and V2:  
Read Community: Specify a name to be identified as the Read Community, and an IP address. This  
community string will be checked against the string entered in the configuration file. Once the string name  
is matched, user obtains this IP address will be able to view the data.  
Write Community: Specify a name to be identified as the Write Community, and an IP address. This  
community string will be checked against the string entered in the configuration file. Once the string name  
is matched, users from this IP address will be able to view and modify the data.  
Trap Community: Specify a name to be identified as the Trap Community, and an IP address. This  
community string will be checked against the string entered in the configuration file. Once the string name  
is matched, users from this IP address will be sent SNMP Traps.  
SNMP V3:  
Specify a name and password for authentication. And define the access right from identified IP address.  
Once the authentication has succeeded, users from this IP address will be able to view and modify the  
data.  
SNMP Version: SNMPv2c and SNMPv3  
SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the SNMPv2 security.  
The "c" comes from the fact that SNMPv2c uses the SNMPv1 community string paradigm for "security",  
but is widely accepted as the SNMPv2 standard.  
SNMPv3 is a strong authentication mechanism, authorization with fine granularity for remote monitoring.  
Traps supported: Cold Start, Authentication Failure.
