Overview

Thank you for purchasing the NetComm NB9/NB9W ADSL2+ VoIP Router. NetComm is proud to introduce this entirely new class of all-in-one device incorporating ADSL2+, VoIP and Wireless in a single compact unit. The NB9/NB9W is truly a ‘broadband communications gateway’ that, when attached to the appropriate ISP services, will enable multiple broadband communications streams to run concurrently into your home or ofﬁce. Data and voice services can be delivered and distributed to multiple PCs at the same time, while the gateway can be managed via ‘Quality of Service’ (QoS) controls to ensure that priority is given to voice trafﬁc, or to the trafﬁc of your choice.

The VoIP ‘terminal adaptor’ capability enables you to connect existing telephones to the device to make inexpensive or free VoIP phone calls to any destination, while simultaneously providing internet connectivity for multiple computers.

Let’s look at some of the capabilities offered by the NB9/NB9W in brief:

ADSL Broadband The NB9/NB9W offers the next generation of

broadband ADSL technology with ADSL2/2+, which boosts ADSL’s performance signiﬁcantly, improves interoperability, and supports new applications, services and deployment conditions.

VoIP The NB9/NB9W connects one or two analogue

telephones to a VoIP service as well as providing a through connection for your existing landline. The two Phone (FXS) ports even allow two separate VoIP numbers with a VoIP Service Provider (VSP). The PSTN Line (FXO) port provides telephone back-up should your VSP or ADSL services or power to the NB9/NB9W fail.

Wireless (NBW only) In addition to fast, standard 802.11g-based wireless,

the NB9W incorporates Broadcom’s state-of-theart XPress and Afterburner technology to radically improve the performance of wirelessly-connected devices.

QoS With the addition of bandwidth-hungry applications

to the SOHO/Home network the NB9/NB9W has not overlooked one of the most important features for a home Internet gateway – Quality of Service (QoS) The QoS implementation in the NB9/NB9W is extremely sophisticated allowing you to prioritise data on your network according to rules you make.

Minimum System Requirements:

Different aspects of the NB9/NB9W have different requirements, so let’s look at them in turn. We’ll start with your computer, which ought to match the following requirements if you are to enjoy the beneﬁts of a high-speed ADSL connection and use of VoIP and Wireless Networking.

PC Requirements:

• Any computer running Windows 98/2000/Me/XP or Macintosh OSX

• Ethernet or Wireless Network card

• CD-ROM drive

• Web browser e.g.

• Internet Explorer 5.1 (or better)

• Netscape Navigator

• Mozilla FireFox 1.0.4

ADSL Requirement:

• ADSL broadband connection to an ISP (Internet Service Provider)

• ADSL Splitter/Filter (see below for details)

Note: Connection at ADSL2 or 2+ rate depends on the service offered by your

ISP; the device will operate at standard ADSL rates in the absence of the 2 or 2+ service. Consult your ISP for details.

VoIP Requirements:

• One or two telephone handsets for VoIP service

Note: The NB9/NB9W serves as an Analogue Terminal Adaptor so any touch-

tone phone may be used for VoIP services

• Account with a VoIP Service Provider (VSP) including relevant account details

Wireless Requirements (for NB9W only):

• Wireless Network Interface Card (NIC) for each intended computer

Do I need a micro filter?

Micro ﬁlters are used to prevent interference between phones and fax machines, and your ADSL service. If your ADSL-enabled phone line is being used with any equipment other than your ADSL Modem then you will need to use one Micro ﬁlter for each phone device in use. Telephones and/or facsimiles in other rooms that are using the same line will also require Microﬁlters. The following diagram gives an example of connecting your ADSL Modem/ Router using a Microﬁlter. A suitable Microﬁlter can be purchased from NetComm or your Service Provider, if required.

A central splitter may be installed with your ADSL service 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 on each device.- Check with your ADSL or phone service provider if you are unsure as to whether a splitter is installed at your premises.

Filters and Multi-purpose Gateways

The multi-purpose ADSL/VoIP gateway uses a different ﬁlter conﬁguration to an ADSL modem/ router. With the NB9/NB9W, an in-line splitter is placed between a non-ﬁltered telephone outlet and the NB9/NB9W. One RJ11 cable is then connected from the splitter’s ‘Line’ port TO the NB9/ NB9W LINE port. Another is connected from the splitters ‘ADSL’ port to the NB9/NB9W ADSL port. This is to allow the ‘pass-through’ line to connect via the POTS if necessary.

If the premises into which the NB9/NB9W is to be used already has a central line-splitter installed, then one line should be connected from the LINE port of the NB9/NB9W to an unﬁltered, POTS telephone point, and another line should be connected from the ADSL port to and ADSL-ready telephone point.

About SIP & VoIP

Voice Settings

The NB9/NB9W has the ability to connect two regular telephones via the Phone1 and Phone2 ports on the rear of the unit and provides a number of sophisticated call-management functions such as call forward, call waiting, call transfer and so on. The following section provides further details of how to set up VoIP services, and then how to use the advanced telephony functions offered by the NB9/NB9W.

Note: You can use separate VoIP accounts from your VoIP Service Provider

but not separate accounts with different VSPs. This means that you can conﬁgure your NB9/NB9W to provide two telephone extensions.

VoIP services are usually provided through a standard technology called SIP, brieﬂy described as follows.

About SIP

SIP, the Session Initiation Protocol, is a signalling protocol for Internet conferencing, telephony, presence, events notiﬁcation and instant messaging. SIP is the Internet Engineering Task Force standard for multimedia conferencing over the Internet. SIP is designed to address the functions of signalling and session management within a packet-switched network. Signalling allows call information to be carried across network boundaries while session management provides the ability to control the qualities and attributes of an end-to-end call.

The Session Initiation Protocol is a peer-to-peer protocol. There are four components in the SIP standard:

• User Agent (UA)

• Proxy Server

• Registrar Server

• Redirect Server

In effect, this means that when you sign up for a VoIP account based on a SIP server, your ‘VoIP’ number and account details are managed by the SIP server at the VoIP Service Provider premises; by entering your SIP details (e.g. ‘sip.serviceprovider.com’) along with your VoIP/SIP account number and your account password, you are ‘registered’ with the service and able to make VoIP calls in practically the same way as with a traditional phone service (but for a much smaller cost.)

Wireless (NB9W only)

Wireless Setup

The NB9W serves as an 802.11g Wireless Access Point, with enhanced capabilities provided by Broadcom’s XPressTM technology. The ﬁrst screen in the Wireless menus is as follows:

Field Enter

Enable Wireless Check Enable Wireless to turn on wireless

transmission

Hide Access Point If this is checked, wireless clients will need to know

the SSID (=wireless network name) if they wish to join the network. If Hide Access point is unchecked, the SSID will be broadcast to any wireless client in range

SSID ‘Station Set Identiﬁer’, or network name; replace

with name of your choice. All stations must be conﬁgured with the correct SSID to access the WLAN. If the SSID does not match, the wireless client will not be able to join the network. Min one character, max 32.

BSSID The BSSID is a 48-bit identity used to identify a

particular BSS (Basic Service Set) within an area. In Infrastructure BSS networks, the BSSID is the MAC (Media Access Control) address of the AP (Access Point) and in Independent BSS or ad-hoc networks, the BSSID is generated randomly.

Wireless Security Quick Setup

Security settings are used to prevent unauthorised connection to your network. This can be as basic as a neighbouring user who detects and is able to connect through your wireless network, right through to actual malicious interference or ‘hacking’. Whatever the case, it is a good practise to be aware of and to use wireless network security to safeguard your data and your network

Prior to considering the details of wireless security – provided later – the Quick Security Setup explains how to implement basic security on your NB9W wireless network.

Quick Security Setup 1: WEP Security

Your NB9W has WEP (Wired Equivalent Privacy) encryption enabled by default. Your network will not be available to passer-by or non-authorised users, and any workstation wishing to connect to your NB9W must know the SSID (wireless network name) and WEP key values.

Turn on wireless, and set the SSID or wireless network name in the Wireless Setup Screen:

Default SSID: wireless. This can continue to be used or changed to the name of your choice.

Next, click on Wireless>Security. You should see that WEP encryption is enabled by default.

Click on Set Encryption Key button to either check, or change, the WEP encryption key:

Default WEP Key: A1B2C3D4E5

Page 32

32 NB9/NB9W ADSL2+ VoIP Router YML790 Rev1

You are able to change these values however it is strongly recommended that security is not turned off. It is also recommended that your SSID or network name not advertise your actual name but be kept ‘generic’ or anonymous.

Note: WEP Security is the appropriate choice if the network clients that wish to

connect include 802.11b standard NICs.

Page 33

NB9/NB9W ADSL2+ VoIP Router 33 YML790 Rev1

Quick Security Setup 2 – WPA-PSK

If an stronger network security setting is required, go to Wireless>Security and select WPAPSK from the drop-down menu. Enter a Network Key of your own choice; this can be from 8 to 63 characters and contain special characters and spaces.

Select TKIP from WPA encryption

Leave WEP as disabled.

Users wishing to connect to your network will need to know the SSID name and the WPA Pre-Shared Key.

Note: Wireless client network cards must be WPA-compliant to connect

to your network; if in doubt check the wireless client network card documentation, or use WEP security (above).

Wireless Security in Detail

The following provides a detailed summary of wireless terms and acronyms and more in-depth explanations of the topic. It assumes little prior knowledge of wireless networking and is aimed at providing background for the terminology used in the NB9W Wireless Security screens.

Warning: Wireless Networking is a technically challenging subject!

Authentication and Encryption

The two major aims of wireless network security are:

(1) to prevent unauthorised persons from joining the network and

(2) to prevent interception of network data or ‘eavesdropping’. These aims are

accomplished by:

• Authentication: establishes the identity of those seeking to join the network

• Encryption: ensures that data is protected in such a way that those outside the network cannot access it.

Network Keys

The term ‘network key’ is often used in the context of wireless networking. The Network Key can be a text string, although in some systems network keys are generated from a ‘pass-phrase’ which is entered in one ﬁeld from which up to four keys are derived in ﬁelds underneath the entry ﬁeld.

In all cases, the Wireless Router/Access Point and the workstations wishing to connect must use the same Network Key which needs to be communicated to clients prior to connection.

‘Re-keying’ refers to the frequency with which network keys are changed; for security purposes, they need to be changed frequently in case they re-occur frequently enough to identify them.

In some wireless systems, network keys are entered by a variety of means including:

• ASCII – any letter, number, or punctuation mark but no special characters

• Hex – Letters A-F, Numbers 0-9 only

• Pass phrase – enter a phrase in the top ﬁeld of a set of ﬁelds, an algorithm then generates a series of keys based on the entered values.

These methods have been standardised in the later implementations of Wireless Security and are easier to use in WPA.

WEP and WPA

‘WEP’ stands for Wireless Equivalent Privacy and was the original wireless security method. Over time it was found to be vulnerable to attacks based on de-coding the ‘keys’ used to encrypt the data. While no longer recommended for enterprise-level security, WEP is certainly secure from casual interception and will repel any non-specialised attempt to join the network or intercept data; it can be penetrated with various kinds of software tools and techniques but these are beyond the capability of the average computer user.

‘WPA’ stands for Wi-Fi Protected Access and is an improvement on WEP. WPA2 offers further reﬁnements to WPA.

Page 35

NB9/NB9W ADSL2+ VoIP Router 35 YML790 Rev1

WPA and WPA2 both comprise a number of different wireless security elements and methods that can be adapted to a variety of situations depending on the requirements. A lot of what is provided is applicable to enterprise-level wireless networking, in other words, suitable for businesses who wish to deploy strict security methods and policies for their employees. Accordingly, these technologies will exceed the requirements of home users.

An important element of WPA security is a RADIUS server (stands for Remote Access Dial-in User Service). The RADIUS server typically sits in the server room of a business or department and authenticates and manages user requests for connection. Home users will generally never have to bother about RADIUS server details.

In nearly all cases, the default security method, which is WEP, or WPA-PSK will provide adequate security for home wireless networks.

Other wireless security elements shall be explained in context below.

Network Authentication

Network Authentication speciﬁes the type of network authentication. The default value is ‘Open’.

Open: Under Open System authentication, any wireless

station can request authentication.

Shared: Under Shared Key authentication, each wireless

station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel (i.e. verbally). To use Shared Key authentication, you must have a network key assigned to the clients trying to connect to your NB9W.

802.1X

802.1X security requires the presence of a RADIUS server, and speciﬁcation of the IP address of a RADIUS server, the port on which to connect to it, and the Shared Key used to authenticate with it.

Disregard this security setting unless you are setting up or connecting to a RADIUS server.

Page 36

36 NB9/NB9W ADSL2+ VoIP Router YML790 Rev1

WPA

WPA also requires a RADIUS server to provide client authentication. 802.1X also requires speciﬁcation of the ‘WPA Group Rekey Interval’ which is the rate that the RADIUS server sends a new Group Key out to all clients. The Re-Keying process is part of WPA’s enhanced security. This method also requires speciﬁcation of the IP address of a RADIUS server, the port on which to connect to the RADIUS server, and the shared key used to authenticate with the RADIUS server.

WPA-PSK

WPA-PSK is a special mode of WPA providing strong encryption without access to a RADIUS server.

In this mode encryption keys are automatically changed (rekeyed) and authentication re-established between devices after a speciﬁed period referred to as the ‘WPA Group Rekey Interval’.

WPA-PSK is far superior to WEP and provides stronger protection for the home/SOHO user for two reasons: ﬁrst, the process used to generate the encryption key is very rigorous and second, the rekeying (or key changing) is done very quickly. This stops even the most determined hacker from gathering enough data to identify the key and so break the encryption.

WEP is confusing because of the various types of ‘network keys’ vendors use (HEX, ASCII, or passphrase) and because home users mix and match equipment from multiple vendors, all using different types of keys. But WPA-PSK employs a consistent, easy to use method to secure your network. This method uses a passphrase (also called a shared secret) that must be entered in both the NB9W and the wireless clients. This shared secret can be between 8 and 63 characters and can include special characters and spaces. The ‘WPA Pre-Shared Key’ should be a random sequence of either keyboard characters (upper and lowercase letters, numbers, and punctuation) at least 20 characters long, or hexadecimal digits (numbers 0-9 and letters A-F) at least 24 hexadecimal digits long.

Note: The less obvious, longer and more ‘random’ your ‘WPA Pre-Shared Key’,

the more secure your network.

Note the following ‘WPA Encryption’ options:

TKIP: The Temporal Key Integrity Protocol (TKIP) takes

over after the initial shared secret is entered in your wireless devices and handles the encryption and automatic rekeying.

AES: WPA deﬁnes the use of Advanced Encryption

Standard (AES) as an additional replacement for WEP encryption. Because you may not be able to add AES support through a ﬁrmware update to your existing wireless clients / equipment, support for AES is optional and is dependent on vendor driver support.

TKIP+AES: This will allow either TKIP or AES wireless clients

to connect to your NB9W.

Page 37

NB9/NB9W ADSL2+ VoIP Router 37 YML790 Rev1

WPA2

‘WPA Pre-authentication’ support in WPA2 allows a client to pre-authenticate with the NB9W toward which it is moving, while maintaining a connection to the access point it’s moving away from. This new capability allows the roaming to occur in less than 1/10th of a second while a traditional roam without PMK caching and pre-authentication would take more than one second. Time-sensitive applications like Citrix, video, or VoIP will all break without fast roaming.

‘Network Re-Auth Interval’ is the interval speciﬁed (seconds) that the wireless client needs to reauthenticate with the NB9W.

For the remainder of the ﬁelds required, see above.

WPA2-PSK: Same as WPA-PSK, but you can only use AES with

WPA2 and not WPA.

Mixed WPA2/WPA: Enables WPA2 or WPA wireless clients to connect

to the NB9W. Requires a RADIUS server to authenticate the wireless clients.

Mixed WPA2/WPA-PSK: Enables WPA2 and WPA clients to authenticate using

a PSK (Pre-Shared Key) instead of a RADIUS server.

Wireless Configuration

To enter advanced settings for the wireless network hosted by the NB9W, click on Wireless > Conﬁguration:

Many of these ﬁelds may not need to be altered and may require interpretation by a network engineer.

Field Name About

AP Isolation ‘On’: ’wireless clients associated with the access

point will only be able to communicate with the Access Point

‘Off’: wireless clients associated with the Access

Point will be able to connect to each other ‘peer-topeer

Band [Not alterable by end-user]

Channel The default channel is 11. The 802.11b/g network is

divided into 14 channels in Australia. Each channel broadcasts on a slightly different frequency; if you are getting interference from adjacent wireless networks, make a note of the channels that these are operating on and change your channel accordingly.

Rate Default rate is ‘Auto’ and operates at the 54 Mbps

data rate when possible but drops to lower rates when necessary, dependent on signal strength and the capacity of the client stations.

Multicast Rate Leave at default setting ‘Auto’ unless there is a

speciﬁc requirement for multicast.

Page 39

NB9/NB9W ADSL2+ VoIP Router 39 YML790 Rev1

Basic Rate Leave as default

Fragmentation Threshold Enter a value between 256 (min) and 2346 (max).

A threshold, speciﬁed in bytes, that determines

whether packets will be fragmented and at what size. On an 802.11 WLAN, packets that exceed the fragmentation threshold are fragmented, i.e., split into smaller units suitable for the circuit size. Packets smaller than the speciﬁed fragmentation threshold value are not fragmented.

If you experience a high packet error rate, try to

slightly increase your ‘Fragmentation Threshold’. The value should remain at its default setting of 2346 unless you are troubleshooting wireless network issues. Setting the ‘Fragmentation Threshold’ too low may result in poor performance.

RTS Threshold Request To Send, set in bytes, speciﬁes the packet

size beyond which the WLAN Card invokes its RTS/CTS (Clear To Send) mechanism. Packets that exceed the speciﬁed RTS threshold trigger the RTS/ CTS mechanism. The NIC (Network Interface Card) transmits smaller packet without using RTS/CTS.

The default setting of 2347 (maximum length)

disables RTS Threshold.

DTIM Interval Delivery Trafﬁc Indication Message (DTIM), also

known as Beacon Rate. The entry range is a value between 1 and 65535. A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the NB9W has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP Clients hear the beacons and awaken to receive the broadcast and multicast messages. The default is 1.

Beacon Interval The amount of time between beacon transmissions.

Each beacon transmission identiﬁes the presence of an wireless client (or access point). By default, WLAN passively scan all RF channels and listen for beacons coming from access points to ﬁnd a suitable access point.

Before a station (wireless client) enters power save

mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point).

Page 40

802.11b equipment.

54g Protection In ‘Auto’ mode the NB9W will use RTS/CTS to

improve 802.11g performance in mixed 802.11g/

802.11b networks. Turn protection ‘Off’ to maximize

802.11g throughput under most conditions.

WMM (Wi-Fi Multimedia) WMM stands for Wi-Fi Multimedia, that provides

Management > SNMP

The Simple Network Management Protocol (SNMP) allows a network administrator to monitor a network by retrieving settings on remote network devices. To do this, the administrator typically runs an SNMP management station program such as MIB browser on a local host to obtain information from the SNMP agent, in this case the NB9/NB9W (if SNMP enabled). An SNMP ‘community’ performs the function of authenticating SNMP trafﬁc. A ‘community name’ acts as a password that is typically shared among SNMP agents and managers.

The ‘System Log’ option under the Status menu allows you to view the system event log, or to conﬁgure the ‘System Log’ options.

Field Means

Read Community Read device settings.

Set Community Read and change device settings.

System Name Default = NB9/NB9W.

Management > SNTP

The SNTP option under Management menu conﬁgures the NB9/NB9W’s time automatically by synchronizing with Internet time servers.

Note: The NB9/NB9W is conﬁgured to Australian EST by default.

Tick the corresponding box displayed on the screen. Then click Save/Apply.

Access Control > Services

The Services Option limits or enables selective access via the LAN or WAN via the following services:

Enable the service by checking the corresponding box and clicking SAVE/APPLY. You will note that all services are enabled for LAN clients and disabled for WAN clients by default.

CAUTION: If you disable HTTP access from the LAN then you may not be able to

open the NB9/NB9W in your Web Browser!

EXAMPLE 1: You need to access your NB9/NB9W via the Internet from a remote

location through a Web browser. Method: enable WAN access for HTTP and click Save and Apply. Then enter the address http://[WAN_IP_NB9/ NB9W] in the browser address bar of the remote machine.

EXAMPLE 2: Assume that you already have a web server on your LAN behind the

NB9W that people connect to from the Internet. You have entered a ‘Port Forwarding’ entry that forwards incoming trafﬁc on the WAN on port 80 to the LAN IP of the web server on port 80 (default for HTTP trafﬁc). If you enable HTTP WAN access to the NB9/NB9W you will be notiﬁed that the default port to access the NB9/NB9W has been updated to port

8080. Therefore, your web server will not need to be reconﬁgured, and you can access your NB9/NB9W on the WAN side using address http:// WAN_IP_OF_NB9/NB9W:8080. The same applies for other services that use conﬂicting ports setup in your NB9/NB9W.

Advanced > LAN

Conﬁgure the NB9/NB9W’s LAN IP address and subnet mask. Save button only saves the LAN conﬁguration data. Save/Reboot button saves the LAN conﬁguration data and reboots the NB9/ NB9W to make the new conﬁguration effective.

Field Means

LAN IP Address Default: 192.168.1.1. The LAN IP address of your

NB9/NB9W.

LAN Subnet Mask Default: 255.255.255.0. The subnet mask of your

NB9/NB9W. A subnet mask is used to determine what subnet an IP address belongs to. For more information on subnetting see http://www.ralphb. net/IPSubnet/.

Loopback IP Address The Loopback address is a special IP number

(127.0.0.1) that is designated for the software loopback interface of a machine. The loopback interface has no hardware associated with it, and it is not physically connected to a network. It is purely there for test purposes.

Loopback Subnet Mask Default: 255.0.0.0. The subnet mask for the loopback

address.

Field Means

Enable UPnP Universal plug and play (UPnP) allows trafﬁc to pass

through the NB9/NB9W for applications using the UPnP protocol. This feature requires one active WAN connection. In addition, the client connecting to the NB9/NB9W should support this feature.

UPnP also supports NAT Traversal which

can automatically solve many NAT-related communications problems. UPnP enables applications to assign dynamic port mappings to the NB9/NB9W and delete them when connections are complete.

A typical example is the MSN Messenger application

that runs on Windows. Instead of manually setting up the port mappings UPnP enables MSN Messenger to make the request to the NB9/NB9W which will setup these ports dynamically. When MSN Messenger is closed the port openings will be removed from the NB9/NB9W’s conﬁguration.

Conﬁgure the second IP address and subnet mask for

LAN interface. It is possible to conﬁgure a second IP address to access the NB9/NB9W on. Once this box is checked you are able to enter the IP address and subnet mask.

Disable DHCP Server Disables the DHCP server. Only to be done if Static

IP address is set up.

Enable DHCP Server Default: Enabled.

Start IP Address Default: 192.168.1.2. The ﬁrst IP address that will

be issued to the ﬁrst DHCP client connecting to the NB9/NB9W using Ethernet cable or wirelessly.

End IP Address Default: 192.168.1.254. The last IP address in the

DHCP pool to be issued to DHCP clients connecting to the NB9/NB9W.

Lease Time Default: 24 hours. The time an IP address is assigned

to a client before behind renewed.

Enable IGMP Snooping IGMP speciﬁes how a host can register a router in

order to receive speciﬁc multicast trafﬁc. IGMP Snooping allows the NB9/NB9W to capture IGMP frames. When your NB9/NB9W hears an IGMP report from a host for a given multicast group it adds the host’s port number for that group. When the NB9/ NB9W hears an IGMP Leave, it removes the host’s port from the table entry.

Page 53

NB9/NB9W ADSL2+ VoIP Router 53 YML790 Rev1

Field Means

Without IGMP snooping, multicast trafﬁc is treated

in the same manner as broadcast trafﬁc - that is, it is forwarded to all ports. With IGMP snooping, multicast trafﬁc of a group is only forwarded to ports that have members of that group. IGMP Snooping generates no additional network trafﬁc, allowing you to signiﬁcantly reduce multicast trafﬁc passing through your NB9/NB9W.

Advanced > NAT > Explanation

NAT stands for Network Address Translation, a process which converts private IP addresses of a computer on the internal private network to one or more public IP addresses for the Internet. NAT changes the packet headers to the new address and keeps track of each session; when packets come back from the Internet, it performs the reverse conversion to the IP address of the client machine.

Web applications operate through ‘open ports’ on devices attached to the Internet by initiating a query which opens a ‘communication session’ with the host through the open port. The presence of the NAT device prevents this process from occurring, as the NAT only admits incoming packets that have been elicited by an outgoing request; other packets are discarded.

However this causes connectivity problems, as any requests originating from applications on the other side of the NAT device - such as requests generated by network gaming and conferencing applications - will not be able to locate a port, and therefore a host, with which to communicate, as their requests are discarded by the NAT. Hence the terms ‘opening’, ‘forwarding’ and ‘mapping’ ports: these processes add information to the NAT table which allows the NAT router to direct incoming requests from selected applications to the appropriate port.

So Port Mapping tells the NAT router: ‘when a request arrives which is intended for TCP port 1357, don’t discard it, but direct it to such-and-such a port’. The port-mapping process invokes advanced routing functionality to ‘bind’ the Port Mapping request to the LAN client from which it originated.

A basic NAT operation is depicted in this illustration:

Page 55

NB9/NB9W ADSL2+ VoIP Router 55 YML790 Rev1

Advanced > NAT > Port Forwarding

Note: This option is not available if your NB9/NB9W is in Bridge mode.

To display the NAT function, you need to have enabled the NAT feature in the WAN Setup. By default, NAT is enabled on your NB9/NB9W

Clicking on Advanced > NAT displays the following:

The Port Forwarding feature allows you to direct incoming trafﬁc from WAN side (identiﬁed by Protocol and External port) to the Internal server with private IP address on the LAN side. The Internal port is required only if the external port needs to be converted to a different port number used by the server on the LAN side. A maximum of 32 entries can be conﬁgured.

For example, you may want to setup an FTP server with IP address 192.168.1.110 on your LAN for people to connect to. The default port that an FTP server listens on is port 21. So, to this set this up you would do the following:

Click on ‘Add’ .

If you are setting up a common server (e.g FTP) you can select the type of server from the dropdown list. Selecting the server will automatically conﬁgure the necessary ports:

Enter the Server’s IP address (e.g. 192.168.1.110)

Click ‘Save / Apply’

Let’s take a look at the ﬁelds on this page.

Field Means

Select a Service Select a type of service you wish to host on your

LAN.

Custom Server Input the name for the custom server.

Server IP address The IP address of the server on your LAN. You

will notice that the ﬁrst 3 octets of the address are automatically input. (e.g. 192.168.1)

you were hosting a video service you would select UDP).

Internal Port Start The internal port refers to the port on the server that

clients try to connect to. (e.g. port 80 on the WAN side for clients trying to connect to a web server).

Internal Port End The internal port end on the server that clients try

to connect to. (e.g. if you are running a service that requires a range of ports to be open you would enter the last port in the range here).

Advanced > NAT > Port Triggering

Port triggering is similar to Port Forwarding however where port forwarding is tied to a speciﬁc IP address, Port triggering is dynamic and is tied to a particular application event request. The ‘Custom Application’ settings, or the pre-sets that are provided by the application names in the drop-down menu, allows speciﬁc ports to be opened by the named applications. The ‘trigger’ is the outgoing request, which then ‘opens’ the ports speciﬁed in the Open Port Start-End range to enable the application to reply.

For this to work, you need to know the Outgoing Port(s) which the application uses to Send requests, and then specify the Open Port range for the reply. Some typical port ranges are as follows; for other applications, check the vendor websites.

networks with a data rate of 10 Mbps. Also known as Category 3 (CAT 3) wiring. See also data rate, Ethernet.

100BASE-T A designation for the type of wiring used by Ethernet

networks with a data rate of 100 Mbps. Also known as Category 5 (CAT 5) wiring. See also data rate, Ethernet.

ADSL Asymmetric Digital Subscriber Line. The most commonly

deployed type of DSL for home users. The term asymmetrical refers to its unequal data rates for downloading and uploading (the download rate is higher than the upload rate). The asymmetrical rates beneﬁt home users because they typically download much more data from the Internet than they upload.

analog Of data, having a form is analogous to the data’s origi-

nal waveform. The voice component in DSL is an analog signal. See also digital.

ATM Asynchronous Transfer Mode A standard for high-speed

transmission of data, text, voice, and video, widely used within the Internet. ATM data rates range from 45 Mbps to 2.5 Gbps. See also data rate.

authenticate To verify a user’s identity, such as by prompting for a

password.

binary The “base two” system of numbers, that uses only two

digits, 0 and 1, to represent all numbers. In binary, the number 1 is written as 1, 2 as 10, 3 as 11, 4 as 100, etc. Although expressed as decimal numbers for convenience, IP addresses in actual use are binary numbers; e.g., the IP address 209.191.4.240 is 11010001.10111111.000001

00.11110000 in binary. See also bit, IP address, network mask.

bit Short for “binary digit,” a bit is a number that can have

two values, 0 or 1. See also binary.

bps bits per second

bridging Passing data from your network to your ISP and vice

versa using the hardware addresses of the devices at each location. Bridging contrasts with routing, which can add more intelligence to data transfers by using network addresses instead. The My ADSL Modem can perform both routing and bridging. Typically, when both functions are enabled, the device routes IP data and bridges all other types of data. See also routing.

broadband A telecommunications technology that can send different

types of data over the same medium. DSL is a broadband technology.

Broadcast To send data to all computers on a network.

server is a computer that is responsible for assigning IP addresses to the computers on a LAN. See DHCP.

digital Of data, having a form based on discrete values ex-

pressed as binary numbers (0’s and 1’s). The data component in DSL is a digital signal. See also analog.

DNS Domain Name System. The DNS maps domain names

into IP addresses. DNS information is distributed hierarchically throughout the Internet among computers called DNS servers. When you start to access a web site, a DNS server looks up the requested domain name to ﬁnd its corresponding IP address. If the DNS server cannot ﬁnd the IP address, it communicates with higher-level DNS servers to determine the IP address. See also domain name.

domain name A domain name is a user-friendly name used in place of

its associated IP address. For example, www.globespan. net is the domain name associated with IP address

209.191.4.240. Domain names must be unique; their assignment is controlled by the Internet Corporation for Assigned Names and Numbers (ICANN). Domain names are a key element of URLs, which identify a speciﬁc ﬁle at a web site, e.g., http://www.globespan.net/index.html. See also DNS.

GRE Generic Routing Encapsulation. TCP/IP protocol suite,

transport layer encapsulation protocol.

hop When you send data through the Internet, it is sent ﬁrst

from your computer to a router, and then from one router to another until it ﬁnally reaches a router that is directly connected to the recipient. Each individual “leg” of the data’s journey is called a hop.

hop count The number of hops that data has taken on its route to its

destination. Alternatively, the maximum number of hops that a packet is allowed to take before being discarded , See also TTL.

IP address Internet Protocol address The address of a host (com-

puter) on the Internet, consisting of four numbers, each from 0 to 255, separated by periods, e.g., 209.191.4.240. An IP address consists of a network ID that identiﬁes the particular network the host belongs to, and a host ID uniquely identifying the host itself on that network. A network mask is used to deﬁne the network ID and the host ID. Because IP addresses are difﬁcult to remember, they usually have an associated domain name that can be speciﬁed instead. See also domain name, network mask.

Microﬁlter In splitterless deployments, a microﬁlter is a device that

removes the data frequencies in the DSL signal, so that telephone users do not experience interference (noise) from the data signals. Microﬁlter types include in-line (installs between phone and jack) and wall-mount (telephone jack with built-in microﬁlter). See also splitterless.

NAT Network Address Translation A service performed by

many routers that translates your network’s publicly known IP address into a Private IP address for each computer on your LAN. Only your router and your LAN know these addresses; the outside world sees only the public IP address when talking to a computer on your LAN.

lowing them to communicate with each other and share resources, such as software, ﬁles, etc.A network can be small, such as a LAN, or very large, such as the Internet.

network mask A network mask is a sequence of bits applied to an IP

address to select the network ID while ignoring the host ID. Bits set to 1 mean “select this bit” while bits set to 0 mean “ignore this bit.” For example, if the network mask

255.255.255.0 is applied to the IP address 100.10.50.1, the network ID is 100.10.50, and the host ID is 1. See also binary, IP address, subnet

NIC Network Interface Card An adapter card that plugs into

your computer and provides the physical interface to your network cabling, which for Ethernet NICs is typically an RJ-45 connector. See Ethernet, RJ-45.

packet Data transmitted on a network consists of units called

packets. Each packet contains a payload (the data), plus overhead information such as where it came from (source address) and where it should go (destination address).

ping Packet Internet (or Inter-Network) Groper A program

used to verify whether the host associated with an IP address is online. It can also be used to reveal the IP address for a given domain name.

PPP Point-to-Point Protocol A protocol for serial data transmis-

sion that is used to carry IP (and other protocol) data between your ISP and your computer. The WAN interface on the My ADSL Modem uses two forms of PPP called PPPoA and PPPoE. See also PPPoA, PPPoE.

PPPoA Point-to-Point Protocol over ATM One of the two types of

PPP interfaces you can deﬁne for a Virtual Circuit (VC), the other type being PPPoE. You can deﬁne only one PPPoA interface per VC.

PPPoE Point-to-Point Protocol over Ethernet One of the two

types of PPP interfaces you can deﬁne for a Virtual Circuit (VC),the other type being PPPoA. You can deﬁne one or more PPPoE interfaces per VC.

protocol A set of rules governing the transmission of data. In order

for a data transmission to work, both ends of the connection have to follow the rules of the protocol.

SDNS Secondary Domain Name System (server) A DNS server

that can be used if the primary DSN server is not available. See DNS.

SNMP Simple Network Management Protocol The TCP/IP proto-

col used for network management.

splitter A device that splits off the voice component of the DSL

signal to a separate line, so that data and telephone service each have their own wiring and jacks. The splitter is installed by your telephone company where the DSL line enters your home. The CO also contains splitters that separate the voice and data signals, sending voice to the PSTN and data on high-speed lines to the Internet. See also CO, PSTN, splitterless, microﬁlter.

splitterless A type of DSL installation where no splitter is installed,

saving the cost of a service call by the telephone company. Instead, each jack in the home carries both voice and data, requiring a microﬁlter for each telephone to prevent interference from the data signal. ADSL is usually splitterless; if you are unsure if your installation has a splitter, ask your DSL provider. See also splitter, microﬁlter.

subnet A subnet is a portion of a network. The subnet is dis-

tinguished from the larger network by a subnet mask which selects some of the computers of the network and excludes all others. The subnet’s computers remain physically connected to the rest of the parent network, but they are treated as though they were on a separate network. See also network mask.

TCP/IP Transmission Control Protocol/Internet Protocol The basic

protocols used on the Internet. TCP is responsible for dividing data up into packets for delivery and reassembling them at the destination, while IP is responsible for delivering the packets from source to destination. When TCP and IP are bundled with higher-level applications such as HTTP, FTP, Telnet, etc., TCP/IP refers to this whole suite of protocols.

Telnet An interactive, character-based program used to access a

remote computer. While HTTP (the web protocol) and FTP only allow you to download ﬁles from a remote computer, Telnet allows you to log into and use a computer from a remote location.

TFTP Trivial File Transfer Protocol. A protocol for ﬁle transfers,

TFTP is easier to use than File Transfer Protocol (FTP) but not as capable or secure.

TTL Time To Live A ﬁeld in an IP packet that limits the life

span of that packet. Originally meant as a time duration, the TTL is usually represented instead as a maximum hop count; each router that receives a packet decrements this ﬁeld by one. When the TTL reaches zero, the packet is discarded.

twisted pair The ordinary copper telephone wiring long used by tel-

ephone companies. It contains one or more wire pairs twisted together to reduce inductance and noise. Each telephone line uses one pair. In homes, it is most often installed with two pairs. For Ethernet LANs, a higher grade called Category 3 (CAT 3) is used for 10BASET networks, and an even higher grade called Category 5 (CAT 5) is used for 100BASE-T networks. See also 10BASE-T, 100BASE-T, Ethernet.

upstream The direction of data transmission from the user to the

Internet.

USB Universal Serial Bus A serial interface that lets you con-

nect devices such as printers, scanners, etc. to your computer by simply plugging them in. The My ADSL Modem is equipped with a USB interface for connecting to a standalone PC.

VC Virtual Circuit A connection from your ADSL router to your

ISP.

VCI Virtual Circuit Identiﬁer Together with the Virtual Path

Identiﬁer (VPI), the VCI uniquely identiﬁes a VC. Your ISP will tell you the VCI for each VC they provide. See also VC.

VPI Virtual Path Identiﬁer Together with the Virtual Circuit

Identiﬁer (VCI), the VPI uniquely identiﬁes a VC. Your ISP will tell you the VPI for each VC they provide. See also VC.

WAN Wide Area Network Any network spread over a large geo-

graphical area, such as a country or continent. With respect to the My ADSL Modem, WAN refers to the Internet.

Web browser A software program that uses Hyper-Text Transfer Pro-

tocol (HTTP) to download information from (and upload to) web sites, and displays the information, which may consist of text, graphic images, audio, or video, to the user. Web browsers use Hyper-Text Transfer Protocol (HTTP). Popular web browsers include Netscape Navigator and Microsoft Internet Explorer. See also HTTP, web site, WWW.

Web page A web site ﬁle typically containing text, graphics and

hyperlinks (cross-references) to the other pages on that web site, as well as to pages on other web sites. When a user accesses a web site, the ﬁrst page that is displayed is called the Home page. See also hyperlink, web site.

Web site A computer on the Internet that distributes information

to (and gets information from) remote users through web browsers. A web site typically consists of web pages that contain text, graphics, and hyperlinks. See also hyperlink, web page.

WWW World Wide Web Also called (the) Web. Collective term for

all web sites anywhere in the world that can be accessed via the Internet.

Appendix B: Cable Information

This cable information is provided for your reference only. Please ensure you only connect the appropriate cable into the correct socket on either this product or your computer.

If you are unsure about which cable to use or which socket to connect it to, please refer to the hardware installation section in this manual. If you are still not sure about cable connections, please contact a professional computer technician or NetComm for further advice.

RJ-45 Network Ports

RJ-45 Network Ports can connect any networking devices that use a standard LAN interface, such as a Hub/Switch Hub or Router. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable to connect the networking device to the RJ-45 Ethernet port. Depending on the type of connection, 10Mbps or 100Mbps, use the following Ethernet cable, as prescribed.

10Mbps: Use EIA/TIA-568-100-Category 3, 4 or 5 cable.

100Mbps: Use EIA/TIA-568-100-Category 5 cable.

Note: To prevent loss of signal, make sure that the length of any twisted-pair

connection does not exceed 100 metres.

Straight and crossover cable configuration

There are two types of the wiring: Straight-Through Cables and Crossover Cables. Category 5 UTP/ STP cable has eight wires inside the sheath. The wires form four pairs. Straight-Through Cables has same pinouts at both ends while Crossover Cables has a different pin arrangement at each end.

In a straight-through cable, wires 1,2,3,4,5,6,7 and 8 at one end of the cable are still wires 1~8 at the other end. In a crossover cable, the wires of 1,2,3,6 are reversed so that wire 1 become 3 at the other end of the cable, 2 becomes 6, and so forth.

To determine which wire is wire 1, hold the RJ-45 cable tip with the spring clip facing towards the ground and the end pointing away from you. The copper wires exposed upwards to your view. The ﬁrst wire on the far left is wire 1. You can also refer to the illustrations and charts of the internal wiring on the following page.
