Introduction
Congratulations on your purchase of the NetComm NB2800 Router. The NetComm NB2800
Router has four built-in 10/100 auto-sensing switched Ethernet ports allowing users to share
files, printers, and other networking resources with each other at a blazing speed. And best of
all, with NAT technology, all users can share a single account for Internet access by connecting
the NetComm NB2800 Router to a DSL/Cable modem.
The router will share your internet connection with up to 253 users. Configured as a DHCP
server, the NetComm NB2800 Router assigns an IP Address to every computer connected on
the Ethernet automatically. Also, a DHCP client helps the WAN port to acquire an IP address
dynamically from your ISP.
Unlike other typical routers, which only share 10Mbps over all of their connections, the
NetComm NB2800 Router is equipped with a 4-port switch, dedicating a possible100Mbps
between each and every ethernet connected computer.
With a web-based UI (User Interface), this NetComm NB2800 Router is easy to setup and
maintain via web browsers such as Netscape Communicator and Internet Explorer.

Chapter 4: Advanced Applications
This chapter provides information on how to set up and use the advanced features of your
NetComm NB2800 Router.
4-1 DHCP Configuration
A DHCP (Dynamic Host Configuration Protocol) Server can automatically assign IP Addresses
to each computer in your network. Unless you already have a DHCP Service on your LAN, it is
highly recommended that you set your router to act as a DHCP server.
Note: The DHCP Server can support a maximum pool of 253 IP Addresses.
■ Dynamic IP Address Select “Enable” to set your Router to act as a DHCP server. If you
already have a DHCP server on your network, set the router’s DHCP option to “Disable”.
■ Starting IP Address Enter a numerical value, from 2 to 254, for the DHCP server to start at
when assigning IP Addresses.
■ Number of Users Enter the maximum number of computers that you want the DHCP
server to assign IP Addresses to, with the absolute maximum being 253.
■ DHCP Clients Table Click the DHCP Clients Table button to show current DHCP client
information.
4-2 Access Control
The Access Control feature allows administrators to block certain users from accessing the
Internet or specific applications. Before using this function, the network computers that you
wish to control should be assigned fixed IP Addresses.
IP Access Setting
Network administrators can restrict access of up to five groups of specified network users/
computers.

■ Protocol Select the protocol type as “TCP” or “UDP” from the drop down box. If you are
not sure which one to choose, select “Both”.
■ Filter Group/LAN IP Range Enter the range of IP addresses which you want to have the
same access limitation (a group).
■ Block Port Range Enter the range of port numbers which are used by the applications you
wish to be blocked. (For example 23 for Telnet)
Here is an example for IP Access Setting. Enter the range of 51~80 in the “Filter Group”
column and 20~80 in the “Block Port Range” column, then click the “Apply” button. As a
result, the user’s computers which have IP Addresses in the range of 192.168.1.51 to
192.168.1.80 will not be able to use the applications which use port numbers from 20 to 80,
such as FTP, Telnet and web browsing.
URL Access Settings
To change to URL Access Settings, select from the menu at the top of the page.
Rev.1 - YML648 www.netcomm.com.au

4-3 Port Forwarding Settings
The Port Forwarding Setting 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 NB2800 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 NB2800 Router supports only one forward to one IP Address for
each port (service).
■ Set up individual network computers to act as servers and configure each with a fixed IP
Address.
■ In the “One Page Setup” screen, ensure the “Private IP Address” is set to the NetComm
NB2800 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.
■ 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.
■ 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.
Rev.1 - YML648 www.netcomm.com.au
NB2800 Router Page 29

4-6 Static Routing
The Static Routing feature allows computers that are connected to the NetComm NB2800
Router directly or through a hub/switch (on the immediate LAN) to communicate with other
computers in the respective LAN segment which are connected to the NetComm NB2800
Router through another router (destination LAN). Up to 20 route entries may be entered into
the NetComm NB2800 Router. The diagram below gives an example of the physical connections
required to use Static Routing.
In the above diagram, PC2 in LAN#2 is connected to the NetComm NB2800 Router via another
router while PC1 in LAN#1 is connected to the NetComm NB2800 Router directly. Without
configuring the Static Routing function, the two computers would not be able to communicate
with each other.
■ Select Route entry Select the route entry number from 1 to 20 that you wish to configure.
■ Destination LAN IP and Subnet Mask Enter the IP Address and Subnet Mask of the
destination LAN that the immediate LAN is to communicate with. T aking the above diagram
as an example, enter 192.168.2.0 in the “Destination LAN IP” field and 255.255.255.0 in
the “Subnet Mask” field.
■ Default Gateway Enter the IP Address of the router that forwards data packets to the
destination LAN. For the above example, enter 192.168.1.2 in the “Default Gateway” field.
■ Hop Count Enter the number of hops required between the LANs to be connected. The
Hop Count represents the “cost” of the routing transmission. The default value is 1.
■ Interface Choose “LAN” if the Destination LAN is on your Router’s LAN side and choose
“WAN” if the Destination LAN is on the Router’s WAN side.
www.netcomm.com.au Rev.1 - YML648

4-11 DDNS Settings
Dynamic Domain Naming Service is a feature which allows your router to notify an Internet
DNS server of your assigned public IP address. The Internet DNS server can then assign a
choosen domain name with your router's public IP address this allocation will then propagate to
other DNS servers on the internet. This is a useful way of allowing people to know your
router's currently assigned Public IP address by referencing your fixed domain name. It is also
useful if you allow remote configuration and need to access your router remotely without
knowing its assigned WAN IP.
Steps to configure DDNS:
1. You must first visit www.dyndns.org and register a domain name from a list of choices.
2. Enable the DDNS service and enter the registered Username, Password and HostName.
3. Click on Apply to save your settings.
4. DDNS is now configured completely. Your choosen HostName will point to your ISP
assigned Public (WAN) IP address automatically.
4-12 VPN Passthrough
Virtual Private Networking (VPN) is a system which allows remote networks to privately
exchange data over an existing public network (usually the Internet). One VPN client can be
used to make one VPN connection (Tunnel) to a VPN Server on the Internet. The NetComm
NB2800 Router supports one single session VPN Passthrough (PPTP or L2TP/IPSec). There is
no configuration necessary for VPN Passthrough.

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.
■ Ensure that your computer and the NetComm NB2800 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.
■ 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 NB2800 Router’s default IP address
of 192.168.1.1
■ Finally, use the Ping command in MS-DOS mode to verify the network connection:
■ Ping 127.0.0.1 to check the TCP/IP stack of your computer.
■ Ping the Router’s IP address (Default: 192.168.1.1) to check for IP connectivity between
your computer and the Router.

Appendix A: Frequently Asked Questions
Q: What is the maximum number of IP Addresses the NetComm NB2800 Router can
support?
The NetComm NB2800 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 NB2800 Router be installed on the network?
In a typical environment, the NetComm NB2800 Router should be installed between the ADSL/
Cable modem and your LAN. Connect the NetComm NB2800 Router to the Ethernet port of
your ADSL/Cable modem, and connect your computers to the RJ45 jack on the LAN side.
Q: Does the NetComm NB2800 Router support IPX or AppleTalk?
No. The NetComm NB2800 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 NB2800 Router can support them.
Q: Does the NetComm NB2800 Router support 100Mb Ethernet?
Yes, the NetComm NB2800 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 NB2800 Router share single user account to multiple users?
The NetComm NB2800 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
www.yahoo.com, is easier to use than its IP address, 204.71.177.70.

The NetComm NB2800 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 NB2800 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 your ISP or you can
browse the Internet to apply for free E-mail accounts.
Q: Can Internet users access LAN computers?
The NetComm NB2800 Router uses NAT to route all in/out band packets. All external users can
only see the IP of the NetComm NB2800 Router but cannot access LAN computers. The LAN
computers are well protected with the NetComm NB2800 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 NB2800 Router support PPTP of VPN packets pass through?
Yes. The NetComm NB2800 Router supports single session PPTP pass through.
Q: Does the NetComm NB2800 Router series support IPsec?
Yes. The NetComm NB2800 Router supports single session IPsec pass through.

Appendix C: Glossary
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.
Adapter
A device that makes the connection to a
network segment, such as Ethernet and
modem cards.
ADSL
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.
Bandwidth
The amount of data that can be transmitted in
a fixed amount of time.
Browser
A software application used to locate and
display Web pages. Examples include
Netscape Navigator and Microsoft Internet
Explorer.
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.
DHCP
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.
Rev.1 - YML648 www.netcomm.com.au
NB2800 Router Page 45
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,
in the URL http://www.pcwebopedia.com/
index.html, the domain name is
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
Also known as Direct Sequence Spread
Spectrum, it is a radio transmission method
that continuously changes frequencies.
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.
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.
IEEE
Short for Institute of Electrical and Electronics
Engineers, an organization best known for
developing standards for the computer and
electronics industry.
Internet
A global network connecting millions of
computers for the exchange of data, news and
opinions.
Intranet
A network based on TCP/IP Protocol
belonging to an organization, and accessible
only by that organization’s members,
employees, or others with authorization.
IP Address
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.
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.
ISP
Short for Internet Service Provider, a
company that provides access to the Internet
for a fee.
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)
MAC Address
Short for Media Access Control Address, a
hardware address that uniquely identifies each
node of a network.
NA T
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.
Network Protocol
Network protocols encapsulate and forward
data packets from one interface to another.
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.
PPP
Short for Point-to-Point Protocol, a
communications protocol for transmitting
information over standard telephone lines
between devices from different manufacturers.
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.
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.
Protocol
An agreed format for transmitting, sending and
receiving data between two devices.

Page 46 NB2800 Router
Router
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.
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.
VPN
The acronym for Virtual Private Network. Via
access control and encryption, VPNs bring 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 provides a high
level of security while the packet is sent over
a large public network.
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.
