Chapter 1: Introduction
Introduction to your Router
Welcome to the VoIP/(802.11g) ADSL2+ (VPN) Firewall Router. The router is an “all-in-one” VoIP ADSL
router, combining an ADSL modem, ADSL router, Ethernet network switch and 2 ports for Voice over IP
functionalities, providing everything you need to get the machines on your network connected to the
Internet over your ADSL broadband connection. With features such as an ADSL 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
Voice over IP Compliance with SIP Standard
The router supports cost-effective, toll-quality voice calls over the Internet. It complies with the most
popular industrial standard, SIP protocol, to ensure the interoperability with SIP devices and major
VoIP Gateways. The VoIP ADSL router supports call waiting, silence suppression, voice activity
detection (VAD), comfort noise generation (CNG), line echo cancellation, caller ID (Bell 202, V3)
and so on.
Fixed-Line Support (Router with LINE port only)
The router integrates RJ-11 FXO port for inbound and outbound calls transmitted through PSTN.
Users can receive phone calls from PSTN while enjoying VoIP call service at the same time. In
addition, the device automatically fallbacks to lifeline POTS to enable making normal phone calls
when there is power outage, or when the Internet connection is down.
Express Internet Access
The router complies with ADSL worldwide standards. It supports downstream rate up to 12/24 Mbps
with ADSL2/2+, 8Mbps with ADSL. Users enjoy not only high-speed ADSL services but also
broadband multimedia applications such as interactive gaming, video streaming and real-time
audio much easier and faster than ever. It is compliant with Multi-Mode standard (ANSI T1.413,
Issue 2; G.dmt (ITU G.992.1); G.lite (ITU G.992.2); G.hs (ITU G994.1); G.dmt.bis (ITU G.992.3);
G.dmt.bis.plus (ITU G.992.5)).
Virtual Private Network (VPN) (BiPAC 7404VGO Only)
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.
802.11g Wireless AP with WPA Support (Wireless Router only)
With integrated 802.11g Wireless Access Point in the router, the device offers a quick and easy
access among wired network, wireless network and broadband connection (ADSL) with single
device simplicity, and as a result, mobility to the users. In addition to 54 Mbps 802.11g data rate, it
also interoperates backward with existing 802.11b equipment. The Wireless Protected Access
(WPA1 and WPA2) and Wireless Encryption Protocol (WEP) supported features enhance the
security level of data protection and access control via Wireless LAN.
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
Chapter 1: Introduction

VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
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
and
PCs from many different vendors. It makes network simple and affordable for users. UPnP
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.
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 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.
Chapter 1: Introduction

VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
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.
Firmware Upgradeable

Cabling
One of the most common causes of problems is bad cabling or ADSL line(s). Make sure that all
connected devices are turned on. On the front of the product is a bank of LEDs. Verify that the LAN Link
and ADSL line LEDs are lit. If they are not, verify that you are using the proper cables.
Ensure that all other devices connected to the same telephone line as your router (e.g. telephones, fax
machines, analogue modems) have a line filter connected between them and the wall socket (unless you
are using a Central Splitter or Central Filter installed by a qualified and licensed electrician), and ensure
that all line filters are correctly installed and the right way around. Missing line filters or line filters installed
the wrong way around can cause problems with your ADSL connection, including causing frequent
disconnections.

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.

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: There are Six options to choose from: Auto, disable, 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 ADSL 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.

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
the DNS of your PC to the LAN IP address of this router.

System
Here are the 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 a 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.

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

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.

General Settings
You can choose not to enable Firewall and still able to access to URL Filter and IM/P2P Blocking or
enable the Firewall using preset filter rules and modify the port 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.
If you choose of the preset security levels and add custom filters, this level of filter rules will be saved
even and do not need to re-configure the rules again if you disable or switch to other firewall 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.

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.

URL Filter
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 the modes that you can choose to check the URL filter rules. The default is set to

Disabled: No action will be performed by the Block Mode.
Always On: Action is enabled.

URL filter rules will be monitoring and checking at all hours of
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.
Chapter 4: Configuration
If yes, then the connection attempt will be
72
VoIP/(802.11g) ADSL2+ (VPN) Firewall 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 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
“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 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 (BiPAC 7404VGO Only)
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.

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.
Dial-In user (server), enter your own username.
If you are a
Password: If you are a Dial-Out user (client), enter the password provided by your Host.
Dial-In user (server), enter your own password.
If you are a
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.

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 128−bit hash.
SHA1: A one-way hashing algorithm that produces a 160−bit 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.

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).

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

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 128−bit hash.
SHA1: A one-way hashing algorithm that produces a 160−bit 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.

Advanced – Parameters
VoIP through IP Interface: IP Interface decides where to send/receive the voip traffic; it includes: ipwan
and iplan. Easy way to select the interface is to check the location of the SIP server. If it locates some
where in the Internet then select ipwan. If the VoIP SIP server is on the local Network then select iplan.
Voice Frame Size: Frame size is available from 10ms to 60ms. Frame size meaning how many
milliseconds the Voice packets will be queued and sent out. It is ideal to have the same frame size in
both of Caller and Receiver.

PSTN Auto-fallback: Whenever VoIP SIP responses error and error code matching with the codes in the
Edit section, the VoiP calls will automatically fallback to PSTN. In the other word, the call will be called
via the PSTN when VoIP SIP returns an error code.
Click the Edit to add or remove the responses code.
To be sure the code is separated by a comma(,).
For more information about SIP responses codes, please check
to link to
http://voip-info.org/wiki/view/sip+response+codes where you can get to know the meaning of each error
code.
Advanced – PSTN Environment Adjustment
PSTN Environment Adjustment options will help you to adjust the onhook and offhook voltage detection
values for your environment. You should use these if the default values are incorrect and result in PSTN
calls not being detected properly, e.g. calls being terminated within 5 seconds of being answered. The
actual levels are determined by your environment including the number and type of telephones used.
Note: ONHOOK means hung up.
To take your phone OFFHOOK, lift the receiver then press Hook/Flash until you hear your normal PSTN
dialtone, not your VoIP dialtone. Wait several seconds and then press Check Level.
You should check the OFFHOOK value for each telephone you have connected to this device. Set the
OFFHOOK voltage to the lowest setting registered for all your telephones, e.g. if your telephones return
values of 4, 5 and 7 then you should set your OFFHOOK voltage to 4.
Note: The detected values will not automatically be set by the Check Level function; you must enter the lowest level
detected after testing all your telephones.

Speed Dial
Speed Dial comes handy to store frequently used telephone numbers which you can press number from
0 to 9 and the pound sign (#) on the phone keypad to activate the function. For example, speed dial to
phone number lists on 9, just press keypad 9 then #. Your router will automatically call out to number
listed on entry 9.
For examples:
If your friend Tim gives you a SIP URL as sip: 89755@192.246.69.223 then you can fill in as
89755@192.246.69.223.
If your friend Felix gives you a SIP URL as sip: felix@iptel.org then you can fill in as felix@iptel.org.
If your friend Greg gives you an IP address "192.246.56.56" only, then you can fill in as “192.246.56.56”.
In case, some of users may use DDNS, you can fill in with domain name as well.
Volume Control
Volume control helps you to adjust the voice quality of telephone to the best comfortable listening level.
Press “-“, the minus sign, to reduce either microphone or/both speaker’s level of your telephone.
Press “+“, the plus sign, to increase either microphone or/both speaker’s level of your telephone.

PSTN Dial Plan (Router with LINE port only)
This section enables you to configure “VoIP with PSTN switching” on your system. You can define a
range of dial plans to make regular call from VoIP switching to PSTN line. Prefix numbers is essential key
to make a distinguishing between VoIP and Regular phone call. If actual numbers dialed matches with
prefix number defined in this dial plan, the dialed number will be routed to the PSTN to make a regular
call. Otherwise, the number will be routed to the VoIP networks.
Reminder! In order to utilize this feature, you must have registered and connected to your SIP Server
first.
Prefix:
Specify number(s) for switching to a PSTN call.
Number of Digits: Specify the total number of digits wish to dial out. Maximum digit number is 15.
Action: Specify a dialing method you wish to make PSTN call(s).
Dial with Prefix: The dialed number with prefix will be sent call through the PSTN.
Note: The actual dialed number of valid digits length requires matching in the Number of Digits filed.
Dial without Prefix: The dialed number will be sent call through the PSTN without prefix.
Note: The actual dialed number of valid digits length requires matching in the Number of Digits filed.
Dial at Timeout: The dialed number will be sent call through the PSTN with the prefix when
timeout starts. This timeout activates when no more digits are dialed in a specific duration.
Note: The actual dialed number of valid digits length MUST NOT exceed in the Number of Digits filed.
Dial at Timeout no Prefix: The dialed number will be sent call through the PSTN without prefix
when timeout starts. This timeout activates when no more digits are dialed in a specific duration.
Note: The actual dialed number of valid digits length MUST NOT exceed in the Number of Digits filed.
Attention
Phone port 1 and 2 will automatically rely to PSTN line when:
- Power Down
- Internet Service Fail, i.e., lost of WAN IP Address
- SIP option is disabled. See VoIP General Setting section.
- Calls match with rule(s) defined in the PSTN Digit Plan.

Virtual Server (known as 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
Chapter 4: Configuration
132
VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
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: User-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

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

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.
Attention
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
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.

Edit DMZ Host
The DMZ Host is a local computer exposed to the Internet. When setting a particular internal IP address
as the DMZ Host, all incoming packets will be checked by the Firewall and NAT algorithms then passed to
the DMZ host, when a packet received does not use a port number used by any other Virtual Server

Time Schedule
The Time Schedule supports up to 16 time slots which helps you to manage your Internet connection. In
each time profile, you may schedule specific day(s) i.e. Monday through Sunday to restrict or allowing the
usage of the Internet by users or applications.
This Time Schedule correlates closely with router’s time, since router does not have a real time clock on
board; it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server
from the Internet. Refer to Time Zone for details. You router time should correspond with your local time.
If the time is not set correctly, your Time Schedule will not function properly.

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 ADSL 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.

Check Email
This function allows you to have the router check your POP3 mailbox for new Email messages. The Mail
LED on your router will light when it detects new messages waiting for download. You may also view the
status of this function using the Status – Email Checking section of the web interface, which also provides
details on the number of new messages waiting. See the Status section of this manual for more
information.
Check Email:
Disable: Check to disable the router’s Email checking function.
Enable: Check to enable the routers email checking function. The following fields will be
activated and required:
Account Name: Enter the name (login) of the POP3 account you wish to check. Normally, it is the text in
your email address before the "@" symbol. If you have trouble with it, please contact your ISP.
Password: Enter the account’s password.
POP3 Mail Server: Enter your (POP) mail server name. You Internet Service Provider (ISP) or network
administrator will be able to supply you with this.
Period: Enter the value in minutes between periodic mail checks.
Automatically dial-out for checking emails: When the function is enabled, your ADSL router will
connect to your ISP automatically to check emails if your Internet connection dropped. Please be careful
when using this feature if your ADSL service is charged by time online.

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.
Chapter 4: Configuration
144
VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
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.
