Introduction  
Congratulations on your purchase of the NetComm ADSL Modem Router. The ADSL Modem  
Router is the perfect solution for connecting a small group of computers to a high-speed  
Broadband Internet connection or to a remote LAN via an ADSL line. The ADSL Modem  
Router supports a maximum downstream data transmission rate of 8Mbps and an upstream rate  
of 640Kbps. Configured as a DHCP server, the ADSL Switch Router assigns an IP Address to  
every connected computer and acts as the only externally recognized Internet device on your  
Local Area Network (LAN). With built-in NAT, the ADSL Modem Router serves as an Internet  
firewall, protecting your network from access by outside users and can also be configured to  
block internal users’ access to the Internet.  
Unlike other routers, which often only share 10Mbps over all of their connections, the  
NetComm ADSL Modem Router is equipped with a 4-port 10M/100Mbps auto-sensing  
switch, dedicating a possible100Mbps to each and every ethernet connected computer. Not only  
will all of your computers be able to enjoy lightning-fast Broadband Internet connections, but  
they will also be able to share internal network data at high speed.  
With a web-based UI (User Interface), this NetComm ADSL Modem Router is easy to setup  
and maintain via web browsers such as Netscape Communicator and Internet Explorer.

Chapter 1: Getting to know your NetComm ADSL Modem  
Router  
This chapter describes the package contents and provides a list of features of the NetComm  
ADSL Modem Router.  
1-1 What is xDSL  
DSL (Digital Subscriber Line) refers to a technology used to increase the data capacity of  
standard twisted-pair wires that are generally used to connect most households to the phone  
network. In addition, this technology allows simultaneous voice and high-speed data  
transmission over a single pair of telephone wires.  
There are seven kinds of DSL service, each with its own compromises between speed, distance,  
cost, and reliability. These services are either symmetrical (data flows at the same speed in both  
directions), or asymmetrical (the downstream capacity is higher than the upstream capacity).  
What is ADSL?  
Asymmetric Digital Subscriber Line (ADSL), as it’s name indicates, is an asymmetrical data  
trasmission technology with higher traffic rates downstream and lower traffic rates upstream. It  
is suitable for Internet users because information is usually downloaded more often than  
uploaded, such as when surfing the web or downloading files.

2-3 What is a Micro filter for?  
Micro filters are used to prevent common telephone equipment, such as phones, answering  
machines and fax machines, from interfering with your ADSL service. If your ADSL enabled  
phone line is being used with any other equipment other than your ADSL Router then you will  
need to use one micro filter for each phone device.  
Splitters may be installed when your ADSL line is installed or when your current phone line is  
upgraded to ADSL. If your telephone line is already split you will not need to use a microfilter  
- check with your ADSL service provider if you are not sure.  
Each micro filter is connected in-line with your telephone or fax machine so that all signals pass  
through it. Telephones and/or facsimiles in other rooms that are using the same extension will  
also require microfilters. The following diagram gives an example of connecting your ADSL  
Modem/Router using a Microfilter.

Gateway, Router and Modem are different working modes that the ADSL Switch Router can use.  
It is highly recommend that you use the Gateway mode, which is NAT enabled. It not only  
allows LAN users to share a single IP Address, but also protects your LAN network from  
outside intruders. If the ADSL Switch Router is set to the Router mode or the Modem mode, all  
the PCs in the LAN will have to be assigned fixed IP Addresses. The Router mode allows users  
to specify which routing path data packets should take. If setting to the Modem mode, the  
Public IP Address setting is not necessary.  
LLC Encaps, Classical IP, PPPoE, and PPPoA are different connection modes that are different  
protocols of making the initial session between your ADSL Switch Router and ISP’s equipment.  
Your ISP may provide the information that which connection mode you should set. If you don’t  
know which one to choose, you have to call your ISP to get this information.  
Gateway using LLC Encaps. (Dynamic IP)  
This connection type is the default setting of this ADSL Switch Router. Choose this setting if:  
1. You want to employ NAT to share Internet access for all of your computers, as well as  
protect them for outside intruders.  
2. Your ISP uses LLC Encapsulation and DHCP to assign IP addresses when you connect. (LLC  
encapsulation allows multiplexing of multiple protocols over a single ATM virtual connection  
(VC). You can find more information in the RFC 2684 standard.)  
Gateway using LLC Encaps. (Static IP)  
Choose this setting according if :  
1. You want to employ NAT to share Internet access for all of your computers, as well as  
protect them for outside intruders.  
2. Your ISP uses LLC Encapsulation and provides you with one or more IP addresses when  
you apply for the service. You can find more information in the RFC 2684 standard.  
I Specify WAN IP Address Enter one IP address provided by your ISP.  
I Subnet Mask Enter the subnet mask values provided by your ISP.  
I Default Gateway IP Address Your ISP will provide you with the Default Gateway IP  
Address.  
I Domain Name Server (DNS) Your ISP will provide you with at least one DNS IP  
Address. Multiple DNS IP settings are common. The first available DNS entry is used in  
most cases.

I Connect-on-demand Is a utility to trigger the PPPoE session to connect if in a disconnected  
status when Internet access is being attempted. Choose “Enable” to make this function  
active, and enter the number of minutes you wish to wait after network idle time in the  
Max Idle Time” location. This function is for PPPoE only.  
I Keep Alive This function keeps your PPPoE connection always on even during a period of  
no WAN activity. In some situations the PPPoE session can not be restored immediately  
after disconnection because the ISP’s system may need time to restore. Check with your ISP  
to ascertain how much time is required before the router starts to re-build the PPPoE session  
and enter this into the “Redial Period” field.  
Gateway using PPPOA  
Choose this setting if:  
1. You want to employ NAT to share Internet access for all of your computers, as well as  
protect them for outside intruders.  
2. Your ISP uses PPPoA as its connection mode. You can find more information in the RFC  
2684 standard.  
I User Name Enter the user name your ISP provide to you.  
I Password Enter the password your ISP provide to you.  
I Connect-on-demand Is a utility to trigger the PPPoA session to connect if in a  
disconnected status when Internet access is being attempted. Choose “Enable” to make this  
function active, and enter the number of minutes you wish to wait after network idle time in  
the “Max Idle Time” location.  
I Keep Alive This function keeps your PPPoA connection always on even it sites idle.  
However, in some situation, PPPoA session can not be built immediately after disconnection  
because the system on ISP site may need a little time to restore. You may need to check your  
ISP to get the information that how much time it need to wait before the router start to re-  
build the PPPoE session and fill it in the “Redial Period”.

4-3 Port Forwarding Settings  
The Port Forwarding Settings application allows you to set up to ten public ports, such as a  
HTTP (web), SMTP (email), FTP, etc. that can be accessed by external users of the Internet.  
Each service is forwarded to a dedicated network computer (server) configured with a fixed LAN  
IP Address. Although the internal service addresses are not directly accessible to the external  
user, the NetComm ADSL Modem Router is able to redirect requests to the appropriate internal  
IP Address/server. To use this application, it is recommended you use a fixed Public IP Address  
from your ISP.  
Note: Your NetComm ADSL Modem Router supports only one forward to one IP  
Address for each port (service).  
I Set up individual network computers to act as servers and configure each with a fixed IP  
Address.  
I In the “One Page Setup” screen, ensure the “Private IP Address” is set to the NetComm  
ADSL Modem Router’s default setting of 192.168.1.1. If a fixed Public IP Address is to be  
used, select “Specify an IP address” and enter the IP Address and other necessary  
information provided by your ISP.  
I Incoming Ports - Enter the desired service port numbers in the “Ports” fields. You can  
specify the protocol type as “TCP” or “UDP” from the drop-down list. If you are not sure  
which one to select, choose “Both”. A selection of commonly used port numbers is  
provided on the right of this screen.  
I Redirect IP Address - Enter the appropriate IP Addresses of the service computers in the  
“Redirect IP Address” locations.  
Example: If the service port number 80~80 (representing an HTTP web address) is entered in  
“Ports” and 192.168.1.100 is entered in “Redirect IP Address”, then all HTTP requests from  
external Internet users will be directed to port 80 of the computer/server with the 192.168.1.100  
fixed IP Address.

Chapter 6: Trouble Shooting  
This chapter provides solutions to problems you may encounter during installation and  
operation of your NetComm ADSL Modem Router.  
Hardware  
T: The Power LED is off.  
Check the power cable is properly connected to the NetComm ADSL Modem Router, the  
power adapter and the socket.  
T: The LAN Link LED is off.  
Check the computer, hub or switch is properly connected to the NetComm ADSL Modem  
Router.  
Check the computer’s Ethernet card is properly installed.  
Check the UTP cable connecting the computer to the Router is connected. This cable should  
not be a crossover cable.  
T: The DIAG LED stays lit.  
The DIAG LED should light up when the device is first powered up to indicate it is checking for  
proper operation. After a few seconds, the LED should go off. If it stays on, the device is  
experiencing a problem. Please contact your dealer.  
T: Why can’t I configure the NetComm ADSL Modem Router?  
First, check whether the NetComm ADSL Modem Router is properly installed or not, including  
the LAN and WAN connections, and all devices’ power.  
Next, check the IP configuration of your computer :  
I For Windows 95/98 users: run Winipcfg.exe or Winipcfg from “Run” on the “Start”  
menu. If there are no IP addresses, click “Release All” and then click “Renew All” to get  
an IP address.  
For Windows NT 4.0/2000/XP users: Open a command prompt and run IpConfig.  
I Ensure that your computer and the NetComm ADSL Modem Router are on the same  
network segment. If you are not sure, initiate the DHCP function and let the computer get an  
IP address automatically from the router.  
I Ensure that your computer is using an IP Address within the range 192.168.1.2 to  
192.168.1.253 and thus compatible with the NetComm ADSL Modem Router’s default IP  
address of 192.168.1.1  
I Finally, use Ping command in MS-DOS mode to verify the network connection:  
I Ping 127.0.0.1 to check the TCP/IP stack of your computer.  
Page 38  
Rev.1 - YML632  
ADSL Modem Router  
Download from Www.Somanuals.com. All Manuals Search And Download.  
I Ping the Router’s IP address (Default: 192.168.1.1) to check for IP connectivity between  
your computer and the Router.  
Note: If you are not able to get to the web configuration screen for the NetComm  
ADSL Modem Router, make sure that you disable the proxy setting within your  
Internet browser and set your browser to access the Internet via the LAN.  
T: What can I do if I have forgotten the password for NetComm ADSL Modem Router?  
You have to reset the Router back to its factory default setting by pushing the Reset button for  
over 3 seconds.  
Note: You will lose all previous settings.  
T: I cannot access my ISP’s home page, why?  
Some ISPs (such as Telstra BigPond) require their host name be specifically configured into your  
computer before you can surf their local web pages. If you are unable to access your ISP’s home  
page, enter your ISP’s Domain Name into the OnePage Setup (3-3) to enable all computers in  
your LAN to access it. If you only want to allow computers to access these home pages, open  
the TCP/IP Properties window (2-4) on these computers, click open the “DNS  
Configuration” tab and enter your ISP’s Domain Name in the “Domain Name Search  
Suffix” location.  
Client Side (Computers)  
T: I can’t browse the Internet via the NetComm ADSL Modem Router  
Ensure your computer can ping or access the Router. See the previous section entitled “Why  
can’t I configure the NetComm ADSL Modem Router” for more information.  
Check the status page of the Router to ensure connection to your ISP has been established.  
T: I get a time out error when I enter a URL or IP address.  
Check if other computers on the LAN are experiencing the same problem. If not, ensure the  
computer’s IP settings are correct (IP Address, Subnet Mask, Gateway IP Address and DNS).  
Check the NetComm ADSL Modem Router’s settings are correct (3-3).

Appendix A: Frequently Asked Questions  
Q: What is the maximum number of IP Addresses the NetComm ADSL Modem Router  
can support?  
The NetComm ADSL Modem Router can support up to 253 IP Addresses in the range of  
192.168.1.2~192.168.1.254.  
Q: Where should the NetComm ADSL Modem Router be installed on the network?  
In a typical environment, the NetComm ADSL Modem Router should be installed between the  
ISP and your LAN. Connect the NetComm ADSL Modem Router to the phone jack which  
supplies the ADSL signal, and connect your computers to the RJ45 jack on the LAN side.  
Q: Does the NetComm ADSL Modem Router support IPX or AppleTalk?  
No. The NetComm ADSL Modem Router was designed to provide a multiple user LAN with  
shared Internet access and supports only the TCP/IP Protocol. If your Novell or Apple system  
is configured with TCP/IP, the NetComm ADSL Modem Router can support them.  
Q: Does the NetComm ADSL Modem Router support 100Mb Ethernet?  
Yes, the NetComm ADSL Modem Router supports both 10Mb & 100Mb Ethernet on the LAN  
side, but only 10Mb on the WAN side.  
Q: What is “NAT” and what is it used for?  
The Network Address Translation (NAT) Protocol translates multiple IP Addresses on a  
private LAN into a single public IP Address that is accessible to the Internet. NAT not only  
provides the basis for multiple IP Address sharing but also provides security, since the multiple  
IP Addresses of LAN computers are never transmitted directly to the Internet.  
Q: How can NetComm ADSL Modem Router share single user account to multiple  
users?  
The NetComm ADSL Modem Router combines the following technologies to enable this  
function.  
NAT (Network address translation): NAT is a technology which can create a private network  
domain behind a public IP. It is usually used as a firewall. It can also be used when there are not  
enough IP Addresses.  
DHCP (Dynamic host configuration protocol): DHCP is a protocol to assign IP Addresses to  
internal computers automatically. It can save a lot of IP Address configuration. This protocol is  
supported by Windows 95/NT, Mac OS, and many other popular OS.  
DNS (Domain name service): DNS is a protocol which translates Domain Names to IP  
addresses that an Internet host can handle. Addressing system using Domain names, like

The NetComm ADSL Modem Router uses standard TCP/IP protocol. It can be operated as  
long as you have TCP/IP protocol installed on your operating system (For example: Windows  
9x, Windows NT, Windows 2000, Windows XP, etc.)  
Q: Can I use multiple E-mail accounts if I use NetComm ADSL Modem Router?  
Yes, you can. Some people think having one Internet account means that they can have only one  
E-mail account. However, E-mail is set by mailbox accounts and different to the account you use  
to connect to your ISP. If you want more E-mail accounts, you can contact with your ISP or  
you can browse the Internet to apply for free E-mail account.  
Q: Can Internet users access LAN computers?  
The NetComm ADSL Modem Router uses NAT to route all in/out band packets. All external  
users can only see the IP of the NetComm ADSL Modem Router but cannot access LAN  
computers. The LAN computers are well protected with the NetComm ADSL Modem Router’s  
natural firewall (NAT). You can allow Internet users access to specific computers by using the  
Port Forwarding, DMZ Host and Special Application options.  
Q: When should I use DMZ host?  
Enable DMZ host when you want to have unrestricted communication between your computer  
and the Internet, for example, playing Internet game (i.e. Ages of Empire) or having multimedia  
conference (i.e. NetMeeting).  
Q: Does the NetComm ADSL Modem Router support PPTP of VPN packets pass  
through?  
Yes. The NetComm ADSL Modem Router supports single session PPTP pass through.  
Q: Does the NetComm ADSL Modem Router series support IPsec?

Bandwidth  
Appendix C: Glossary  
The amount of data that can be transmitted in  
a fixed amount of time.  
10Base-T / 100Base-T  
The adaptation of the Ethernet standard for  
Local Area Networks (LANs). 10Base-T uses  
a twisted pair cable with maximum lengths of  
100 meters and transmits data at 10Mbps  
maximum. 100Base-T is similar, but uses two  
different twisted pair configurations and  
transmits at 100Mbps maximum.  
Browser  
A software application used to locate and  
display Web pages. Examples include  
Netscape Navigator and Microsoft Internet  
Explorer.  
BSS  
Ad-hoc Network  
BSS is the acronym of Basic Service Set that  
is consisted a wireless access point and a  
group of wireless client computers.  
Also known as the peer-to-peer network, an  
ad-hoc network allows all computers  
participating in a wireless network to  
communicate each other without an  
AccessPoint.  
Communications Protocols  
Communication between devices requires they  
agree on the format in which the data is to be  
transmitted, sent and received. The  
communications protocols are a set of rules  
that define the data format.  
Adapter  
A device that makes the connection to a  
network segment, such as Ethernet and  
modem cards.  
DHCP  
ADSL  
DHCP, short for Dynamic Host Configuration  
Protocol, is a protocol for assigning dynamic  
IP Addresses to devices on a network.  
Dynamic Addressing means that a device can  
have a different IP Address each time it  
connects to the network.  
Asymmetric Digital Subscriber Line (ADSL),  
as its name indicates, is an asymmetrical data  
transmission technology with higher traffic  
rate downstream and lower traffic rate  
upstream. ADSL technology satisfies the  
bandwidth requirements of applications which  
demand “asymmetric” traffic, such as web  
surfing, file downloads, and telecommuting.  
Domain Name  
A name that identifies one or more IP  
Addresses. For example, the domain name  
microsoft.com represents about a dozen IP  
Addresses. Domain names are used in URLs  
to identify particular Web pages. For example,  
index.html, the domain name is  
ATM  
Asynchronous Transfer Mode is a network  
technology supports real time voice, video,  
and data transmission. The topology uses  
switches that establish a logical circuit from  
end to end, which guarantees quality of  
service (QoS). ATM works by transmitting all  
traffic as fixed-length, 53-byte cells. This fixed  
unit allows very fast switches to be built  
ATM is widely used as a backbone  
technology in carrier networks and large  
enterprises. ATM is highly scalable and  
supports transmission speeds of 1.5, 25, 100,  
155, 622, 2488 and 9953 Mbps. ATM is also  
running as slow as 9.6 Kbps between ships at  
sea.  
pcwebopedia.com.  
DNS  
Short for Domain Name Server, translates  
domain names into IP Addresses. To help us  
recognize and remember domain names they  
are alphabetic in form, however, the Internet  
actually runs on numbered IP Addresses.  
DNS servers translate domain names into their  
respective IP Addresses.

DSSS  
IP Address  
Also known as Direct Sequence Spread  
Spectrum, it is a radio transmission method  
that continuously changes frequencies.  
An identifier for a computer or device on a  
TCP/IP network. Networks using the TCP/IP  
Protocol route messages based on the IP  
Address of the destination. The format of an  
IP address is a 32-bit numeric address written  
as four numbers separated by periods. Each  
number can be from zero to 255.  
Ethernet  
One of the most common Local Area Network  
(LAN) standards. Ethernet uses a bus  
topology which supports a data transfer rate  
of 10 or 100 Mbps.  
IPSec  
Internet Protocol Security is a security  
standard for network transmission, which is  
often used for VPN connections. It provides  
authentication and packet encryption over the  
Internet.  
ESS  
ESS is the acronym of Extend Service Set that  
consists of several BSS.  
Firewall  
A security system used to enforce an access  
control policy between an organisation’s  
networks and the Internet.  
ISP  
Short for Internet Service Provider, a  
company that provides access to the Internet  
for a fee.  
IEEE  
Short for Institute of Electrical and Electronics  
Engineers, an organization best known for  
developing standards for the computer and  
electronics industry.  
Local Area Network (LAN)  
A computer network that spans a relatively  
small area. Most LANs are confined to a  
single building or group of buildings.  
However, one LAN can be connected to other  
LANs over any distance. A system of LANs  
connected in this way is called a wide area  
network (WAN)  
Internet  
A global network connecting millions of  
computers for the exchange of data, news and  
opinions.  
MAC Address  
Intranet  
Short for Media Access Control Address, a  
hardware address that uniquely identifies each  
node of a network.  
A network based on TCP/IP Protocol  
belonging to an organization, and accessible  
only by that organization’s members,  
employees, or others with authorization.  
NAT  
Infrastructure Network  
Short for Network Address Translation, a  
routing protocol that allows global IP  
Addresses to be translated into multiple  
private IP Addresses for use on internal LAN  
networks. The explosion in the use of the  
Internet has created a critical problem for the  
Internet Assigned Numbers Authority  
(IANA) which is in charge of assigning IP  
Addresses to Internet users, ISPs etc. NAT is  
a technology that has been introduced to help  
maximize the utilization of assigned IANA  
and global IP Addresses.  
Unlike an ad-hoc network (where users on a  
wireless LAN send data to each other  
directly), users on an infrastructure network  
send data through a dedicated access point.  
Additionally, the access point enables users  
on a wireless LAN to access an existing wired  
network to take advantage of sharing the  
wired networks resources, such as files,  
printers, and Internet access.

Network Protocol  
Router  
Network protocols encapsulate and forward  
data packets from one interface to another.  
An Internet device that routes requests for  
information to other routers until the  
information’s location is found and the data  
can be transmitted back to the origin of the  
request.  
PAP/CHAP  
Short for Password Authentication Protocol  
and Challenge Handshake Authentication  
Protocol. Most ISPs use either one for user  
identification. If your ISP doesn’t support  
these two protocols, contact them for an  
authentication script.  
TCP/IP  
Short for Transmission Control Protocol and  
Internet Protocol, the suite of communications  
protocols that enable hosts on the Internet to  
connect and exchange streams of data.  
PPP  
VPN  
Short for Point-to-Point Protocol, a  
communications protocol for transmitting  
information over standard telephone lines  
between devices from different manufacturers.  
The acronym for Virtual Private Network. Via  
access control and encryption, VPN brings the  
security to the data transmission through the  
Internet as it is transmitted through a private  
network. It not only takes advantage of  
economies of scale but also secures a high  
level of security while the packet is sent over  
the large public network.  
PPPoE  
Short for PPP over Ethernet, relying on two  
widely accepted standards, Ethernet and the  
Point-to-Point Protocol. PPPoE is a  
communications protocol for transmitting  
information over the Ethernet between  
devices from different manufacturers.  
Wide Area Network (WAN)  
A system of LANs being connected by  
telephone lines and radio waves. Although  
some WANs may be privately owned, they  
are usually considered a means of public  
access.  
PPTP  
The acronym of Point to Point Tunnelling  
Protocol, PPTP encapsulates the packet for  
transmission over the Internet. It creates a  
private “tunnel” through the large public  
network to have similar security of private  
network without actually leasing a private  
line. PPTP is normally used for VPN  
connections.  
WEP  
The acronym for Wired Equivalent Privacy. It  
is an encryption mechanism used to protect  
your wireless data communications. WEP  
uses a combination of 64-bit/128-bit keys to  
encrypt data that is transmitted between all  
points in a wireless network to ensure data  
security. It is described in the IEEE 802.11  
standard.  
Protocol  
An agreed format for transmitting, sending and  
receiving data between two devices.  
Roaming  
The ability for a wireless device moves from  
one access point’s range to another without  
losing the connection.
