Chapter 1
Introduction
This Chapter provides an overview of the ADSL VoIP Router's features and
capabilities.
Congratulations on the purchase of your new ADSL VoIP Router. The ADSL VoIP Router is a
multi-function device providing the following services:
•ADSL Modem.
•Shared Broadband Internet Access for all LAN users.
•Wireless Access Point for 802.11b and 802.11gWireless Stations.
•1 Ethernet port for 10BaseT or 100BaseT connections.
•1 FXS for telephone
•1 FXO for PSTN
•Optional USB port for USB connection
Figure 1: ADSL VoIP Router
ADSL VoIP Router Features
The ADSL VoIP Router incorporates many advanced features, carefully designed to provide
sophisticated functions while being easy to use.
Internet Access Features
•Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the ADSL VoIP Router, using only a single external IP Address. The local (invalid)
IP Addresses are hidden from external sources. This process is called NAT (Network Ad-
dress Translation).

•Built-in ADSL Modem. The ADSL VoIP Router has a built-in ADSL modem, support-
ing all common ADSL connections.
•IPoA, PPPoE, PPPoA, Direct Connection Support. The ADSL VoIP Router sup-
ports all common connection methods.
•Auto-detection of Internet Connection Method. In most situations, the ADSL VoIP
Router can test your ADSL and Internet connection to determine the connection method
used by your ISP.
•Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the ADSL
VoIP Router supports both Dynamic IP Address (IP Address is allocated on connection)
and Fixed IP Address.
Advanced Internet Functions
•Application Level Gateways (ALGs). Applications which use non-standard connec-
tions or port numbers are normally blocked by the Firewall. The ability to define and allow
such applications is provided, to enable such applications to be used normally.
•Special Applications. This feature, also called Port Triggering, allows you to use
Internet applications which normally do not function when used behind a firewall.
•Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
•Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows
users to connect to Servers on your LAN using a Domain Name, even if you have a dy-
namic IP address which changes every time you connect.
•URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
•Firewall. As well as the built-in firewall to protect your LAN, you can define Firewall
Rules to determine which incoming and outgoing traffic should be permitted.
•Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate only at
certain times. This provides great flexibility in controlling Internet-bound traffic.
•Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog
Server. Log data can also be E-mailed to you.
•VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using
PPTP, L2TP and IPSec are transparently supported -no configuration is required.
Wireless Features
•Standards Compliant. The ADSL VoIP Router complies with the IEEE802.11g(DSSS)
specifications for Wireless LANs.
•Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard
provides for backward compatibility with the 802.11b standard, so both 802.11b and 802.11g
Wireless stations can be used simultaneously.
•Speeds to 54Mbps. All speeds up to the 802.11gmaximum of 54Mbps are supported.
•WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64
Bit and 128 Bit are supported. WEP encrypts any data before transmission, providing pro-
tection against snoopers.
•WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission,
providing protection against snoopers. The WPA-PSK is a later standard than WEP, and
provides both easier configuration and greater security than WEP.

Introduction

•Wireless MAC Access Control. The Wireless Access Control feature can check the
MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless
Stations can access your LAN.
•Simple Configuration. If the default settings are unsuitable, they can be changed
quickly and easily.
LAN Features
•1Ethernet port.The ADSLVoIP Router incorporates a 1-port 10/100BaseT, making it
easy to create or extend your LAN.
•1 Optional USB port.
•DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The ADSL VoIP Router can act as a DHCP
Server for devices on your local LAN and WLAN.
Configuration & Management
•Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configura-
tion.
•Configuration File Upload/Download. Save (download) the configuration data from
the ADSL VoIP Router to your PC, and restore (upload) a previously-saved configuration
file to the ADSL VoIP Router.
•Remote Management. The ADSL VoIP Router can be managed from any PC on your
LAN or Wireless LAN. And, if the Internet connection exists, it can also (optionally) be
configured via the Internet.
•Network Diagnostics. You can use the ADSL VoIP Router to perform a Ping or DNS
lookup.
Security Features
•Password -protected Configuration. Password protection is provided to prevent
unauthorized users from modifying the configuration data and settings.
•Wireless LAN Security. WPA-PSK, WEP and Wireless access control by MAC ad-
dress are all supported. The MAC-level access control feature can be used to prevent
unknown wireless stations from accessing your LAN.
•NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-
nology is that by allowing all LAN users to share a single IP address, the location and even
the existence of each PC is hidden. From the external viewpoint, there is no network, only a
single device -the ADSL VoIP Router.
•Firewall. All incoming data packets are monitored and all incoming server requests are
filtered, thus protecting your network from malicious attacks from external sources.
•Protection against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much band-
width and so many resources that Internet access becomes unavailable. The ADSL VoIP
Router incorporates protection against DoS attacks.

If you can't connect
If the ADSL VoIP Router does not respond, check the following:
•The ADSL VoIP Router is properly installed, LAN connection is OK, and it is
powered ON. You can test the connection by using the "Ping" command:
•Open the MS-DOS window or command prompt window.
•Enter the command:
ping 192.168.0.1
If no response is received, either the connection is not working, or your
PC's IP address is not compatible with the ADSL VoIP Router'sIP Address.
(See next item.)
•If your PC is using a fixed IP Address, its IP Address must be within the range
192.168.0.2 to 192.168.0.254 to be compatible with the ADSL VoIP Router's de-
fault IP Address of 192.168.0.1. Also, the Network Mask must be set to
255.255.255.0. See Chapter 4 -PC Configuration for details on checking your
PC's TCP/IP settings.
•Ensure that your PC and the ADSL VoIP Router are on the same network
segment. (If you don't have a router, this must be the case.)

Data -LAN Screen
TCP/IP
IP Address IP address for the ADSL VoIP Router, as seen from the local LAN. Use
the default value unless the address is already in use or your LAN is
using a different IP address range. In the latter case, enter an unusedIP
Address from within the range used by your LAN.
Subnet Mask The default value 255.255.255.0 is standard for small (class "C") net-
works. For other networks, use the Subnet Mask for the LAN segment
to which the ADSL VoIP Router is attached (the same value as the PCs
on that LAN segment).
DHCP Server •If Enabled, the ADSL VoIP Router will allocate IP Addresses to PCs
(DHCP clients) on your LAN when they start up. The default (and
recommended) value is Enabled.
•If you are already using a DHCP Server, this setting must be
Disabled, and the existing DHCP server must be re-configured to
treat the ADSL VoIP Router as the default Gateway. See the follow-
ing section for further details.
•The Start IP Address and Finish IP Address fields set the values
used by the DHCP server when allocating IP Addresses to DHCP
clients. This range also determines the number of DHCP clients
supported.
See the following section for further details on using DHCP.
DHCP
What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP
Client (PC or device) upon request.
•The client request is made when the client device starts up (boots).
•The DHCP Server provides the Gateway and DNS addresses to the client, as well as
allocating an IP Address.

ADSL VoIP Router User Guide
16
•The ADSL VoIP Router can act as a DHCP server.
•Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client.
This is the default Windows setting for the TCP/IP network protocol. However, Windows
uses the term Obtain an IP Address automatically instead of "DHCP Client".
•You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your
LAN does not have other Routers, this means there must only be one (1) DHCP Server on
your LAN.)
Using the ADSL VoIP Router's DHCP Server
This is the default setting. The DHCP Server settings are on the LANscreen. On this screen,
you can:
•Enable or Disable the ADSL VoIP Router'sDHCP Server function.
•Set the range of IP Addresses allocated to PCs by the DHCP Server function.
You can assign Fixed IP Addresses to some devices
while using DHCP, provided that the Fixed IP Addresses
are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP
Server, rather than the ADSL VoIP Router's, the following procedure is required.
•Disable the DHCP Server feature in the ADSL VoIP Router. This setting is on the LAN
screen.
•Configure the DHCP Server to provide the ADSL VoIP Router's IP Address as the Default
Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP for all non-Server versions of Windows.
See Chapter 4 -Client Configuration for the procedure to check these settings.
