BEFORE YOU USE
Thank you for purchasing a NetComm ADSL2+ Modem Router. NetComm brings you the Next Generation of
ADSL technology with ADSL2+*, which boosts ADSL’s performance, improves interoperability, and supports
new applications, services and deployment conditions.
NetComm’s implementation of ADSL2+* ensures that your Modem Router operates with existing ADSL
services while delivering optimal performance in all modes of operation. Powered by the latest Broadcom
ADSL+2* chipset, NetComm’s Modem Router provides downstream data rates of up to 24Mbps in ADSL2+*
mode ensuring that you can surf the net or download your files quicker than ever before.
Security is a key issue with Broadband users and NetComm’s Modem Routers do not leave you exposed.
Your new Modem Router has a built-in firewall to ensure your defences are rock-solid against hackers,
unauthorised entries, probes and even Denial of Service attacks. What’s more, your Modem Router is
equipped with a VPN pass-through feature allowing you to use a standard VPN client for Point-to-Point
communication even while your Firewall is active.
NetComm’s NB6 Series Modem Routers deliver the connection versatility needed to cater for today’s ADSL
users. Simply attach to a single PC using the Ethernet port (recommended) or USB port. Alternatively, should
you wish to share your Internet connection, the Modem Router is equipped with an in-built Router and one or
four Ethernet ports for connection to a network. If you have the NB6W or NB6Plus4W modem, you can also
share your Internet connection wirelessly.
The Modem Router’s Port Forwarding and UPnP functions have made it easier for today’s Internet users
to configure and setup the myriad of Network Port Rules needed by Internet applications such as On-Line
Gaming, Peer-To-Peer file sharing and Messenger services to operate. The Modem Router has a number of
pre-configured rules for several games, just click on the game you wish to play on-line and the rest is done
for you.
Added to this, the Modem Router introduces a QoS (Quality of Service) feature that gives you control over
which types of data are given priority by the Modem Router.
* Your ISP must support and provide you with an ADSL-2 or ADSL-2+ service for these features to be available. This product will operate
as a standard ADSL Modem Router when an ADSL-2 service is not available.
This reference manual assumes that the reader has an installed Ethernet card in the computer to be connected and has basic to
intermediate computer and Internet skills. However, basic Computer Networking, Internet, and Firewall technology information is
available from the NetComm Web site. See www.netcomm.com.au.

Dynamic IP: If you apply for an on-demand connection, you will be given an Internet account
with username and password. You will get a dynamic IP issued by your ISP, such
as under PPPoA, PPPoE, or MER mode.
Static IP address: If you apply for full-time connectivity, you may get either one static IP address
or a range of IP addresses from your ISP. The IP address varies according to
different ADSL service provider, such as using IPoA or MER mode.

CHAPTER 2: SYSTEM REQUIREMENT AND
INSTALLATION
System Requirements
Before continuing with the installation of your Modem Router please confirm that you comply with the
minimum system requirements.
• Pentium® MMX 233MHz
• A CD-ROM Drive
• Ethernet card installed with TCP/IP Protocol
(required when connecting to the ETHERNET port of your ADSL Router)
• OS independent for Ethernet
• USB Port (required only if you are connecting to the USB Port of your ADSL Router)
• Host Operating Systems support for USB:
• Windows® 98 Second Edition
• Windows® 2000
• Windows® Me
• Windows® XP (recommended)
• Web Browser support:
• Microsoft Internet Explorer 5.0 (or later versions)
• Netscape® Navigator 4.0 (or later versions)
• Most popular browsers
To access the ADSL Router via Ethernet (Recommended), the host computer must meet the following
requirements:
• Equipped with an Ethernet network interface.
• Have TCP/IP installed.
• Allow the client PC to obtain an IP address automatically or set a fixed IP address.
• With a web browser installed: Internet Explorer 5.x or later.
The ADSL Router is configured with the default IP address of 192.168.1.1 and subnet mask of
255.255.255.0. Considering that the DHCP server is Enable by default, the DHCP clients should be able to
access the ADSL Router, or the host PC should be assigned an IP address first for initial configuration.
You also can manage the ADSL Router through a web browser-based manager: ADSL ROUTER CONTROL
PANEL. The ADSL Router manager uses the HTTP protocol via a web browser to allow you to set up and
manage the device.
To configure the device via web browser, at least one properly-configured PC must be connected to the network (either connected
directly or through an external hub/switch to the LAN port of the device).

Do I need a Micro filter?
An ADSL Microfilter filters out ADSL signals to allow ADSL and regular Voice Calls to share a single telephone line.
Any equipment sharing your ADSL telephone line, other than an ADSL modem must be connected to a
telephone jackpoint via a microfilter. Examples of such non-ADSL equipment that MUST connect through a
microfilter are :
• Telephone Handset
• Fax Machine
• Foxtel digital set
• Back to base alarm
• Modem (non adsl)
• Caller display unit
• Other devices that have an integral modem
Failure to connect ALL non-ADSL equipment via a microfilter may result in loss of the data link whenever a call
is made or answered. In many cases the link will also be lost when a call is received even if it is not answered.
