BEFORE YOU USE

Thank you for purchasing a NetComm ADSL2+ Modem Router. NetComm brings you the Next Generation of ADSL technology with ADSL2+*, which boosts ADSL’s performance, improves interoperability, and supports new applications, services and deployment conditions.

NetComm’s implementation of ADSL2+* ensures that your Modem Router operates with existing ADSL services while delivering optimal performance in all modes of operation. Powered by the latest Broadcom ADSL+2* chipset, NetComm’s Modem Router provides downstream data rates of up to 24Mbps in ADSL2+* mode ensuring that you can surf the net or download your ﬁles quicker than ever before.

Security is a key issue with Broadband users and NetComm’s Modem Routers do not leave you exposed. Your new Modem Router has a built-in ﬁrewall to ensure your defences are rock-solid against hackers, unauthorised entries, probes and even Denial of Service attacks. What’s more, your Modem Router is equipped with a VPN pass-through feature allowing you to use a standard VPN client for Point-to-Point communication even while your Firewall is active.

NetComm’s NB6 Series Modem Routers deliver the connection versatility needed to cater for today’s ADSL users. Simply attach to a single PC using the Ethernet port (recommended) or USB port. Alternatively, should you wish to share your Internet connection, the Modem Router is equipped with an in-built Router and one or four Ethernet ports for connection to a network. If you have the NB6W or NB6Plus4W modem, you can also share your Internet connection wirelessly.

The Modem Router’s Port Forwarding and UPnP functions have made it easier for today’s Internet users to conﬁgure and setup the myriad of Network Port Rules needed by Internet applications such as On-Line Gaming, Peer-To-Peer ﬁle sharing and Messenger services to operate. The Modem Router has a number of pre-conﬁgured rules for several games, just click on the game you wish to play on-line and the rest is done for you.

Added to this, the Modem Router introduces a QoS (Quality of Service) feature that gives you control over which types of data are given priority by the Modem Router.

* Your ISP must support and provide you with an ADSL-2 or ADSL-2+ service for these features to be available. This product will operate

as a standard ADSL Modem Router when an ADSL-2 service is not available.

This reference manual assumes that the reader has an installed Ethernet card in the computer to be connected and has basic to

intermediate computer and Internet skills. However, basic Computer Networking, Internet, and Firewall technology information is available from the NetComm Web site. See www.netcomm.com.au.

CHAPTER 2: SYSTEM REQUIREMENT AND

INSTALLATION

System Requirements

Before continuing with the installation of your Modem Router please conﬁrm that you comply with the minimum system requirements.

• Pentium® MMX 233MHz

• A CD-ROM Drive

• Ethernet card installed with TCP/IP Protocol

(required when connecting to the ETHERNET port of your ADSL Router)

• OS independent for Ethernet

• USB Port (required only if you are connecting to the USB Port of your ADSL Router)

• Host Operating Systems support for USB:

• Windows® 98 Second Edition

• Windows® 2000

• Windows® Me

• Windows® XP (recommended)

• Web Browser support:

• Microsoft Internet Explorer 5.0 (or later versions)

• Netscape® Navigator 4.0 (or later versions)

• Most popular browsers

To access the ADSL Router via Ethernet (Recommended), the host computer must meet the following requirements:

• Equipped with an Ethernet network interface.

• Have TCP/IP installed.

• Allow the client PC to obtain an IP address automatically or set a ﬁxed IP address.

• With a web browser installed: Internet Explorer 5.x or later.

The ADSL Router is conﬁgured with the default IP address of 192.168.1.1 and subnet mask of

255.255.255.0. Considering that the DHCP server is Enable by default, the DHCP clients should be able to access the ADSL Router, or the host PC should be assigned an IP address ﬁrst for initial conﬁguration.

You also can manage the ADSL Router through a web browser-based manager: ADSL ROUTER CONTROL PANEL. The ADSL Router manager uses the HTTP protocol via a web browser to allow you to set up and manage the device.

To conﬁgure the device via web browser, at least one properly-conﬁgured PC must be connected to the network (either connected directly or through an external hub/switch to the LAN port of the device).

An ADSL Microﬁlter ﬁlters out ADSL signals to allow ADSL and regular Voice Calls to share a single telephone line.

Any equipment sharing your ADSL telephone line, other than an ADSL modem must be connected to a telephone jackpoint via a microﬁlter. Examples of such non-ADSL equipment that MUST connect through a microﬁlter are :

• Telephone Handset

• Fax Machine

• Foxtel digital set

• Back to base alarm

• Modem (non adsl)

• Caller display unit

• Other devices that have an integral modem

Failure to connect ALL non-ADSL equipment via a microﬁlter may result in loss of the data link whenever a call is made or answered. In many cases the link will also be lost when a call is received even if it is not answered.

Bridge Mode

Description:

In this example, the ADSL Router acts as a bridge which bridging the PC IP addresses from LAN to WAN. The PC IP address can be a static public address that is pre-assigned by the ISP or a dynamic public address that is assigned by the ISP DHCP server, or an IP address received from PPPoE software.

Therefore, it does not require a public IP address. It only has a default private IP address (192.168.1.1) for management purpose.

Conﬁguration:

1. Choose a client PC and set the IP as 192.168.1.x (x is between 2 and 254) and the gateway as

192.168.1.1.

2. Start your browser and type 192.168.1.1 in the URL box to access ADSL web-based manager.

Local Network – IGMP Snooping

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or Broadcast (1 sender to everyone on the network). Multicast delivers IP packets to just a group of hosts on the network.

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 switch.

The ﬁgure below shows a simple network connected via this ADSL router. There are four Ethernet clients, one using USB, and two wireless clients.

Now suppose the video server is the multicast transmitter and host A and D are multicast receivers. If we do not turn on the IGMP snooping function, the router will forward the multicast trafﬁc to all hosts on all interfaces and consequently block and interrupt the trafﬁc of USB and wireless users, shown as the following ﬁgure.

YML854 Rev1 NB6, NB6W, NB6Plus4WNB6, NB6W, NB6Plus4W User Guide www.netcomm.com.au 67

When IGMP snooping is invoked, it makes the system aware to establish the best path for multicast service to save LAN bandwidth. Refer the ﬁgure below, just as desired, only host A and D will actually receive multicast trafﬁc when IGMP snooping is enabled.

While IGMP snooping is enabled, the IGMP packets will be monitored, the membership information will be recorded and processed, and the multicast trafﬁc will only be forwarded to those LAN interfaces, such as Ethernet, Wireless, and USB, which are bonded to the subscribed multicast groups. Thus it helps to save the bandwidth and helps the devices to perform more effectively.

Check Enable IGMP Snooping and click Apply to invoke this function.

If the PVC you’re using is NAT enabled, remember to turn on the IGMP Proxy at the same time. Please refer to Internet – IGMP Proxy for more information.

Note that the IGMP proxy must be enabled ﬁrst. If the IGMP Snooping function is not available as shown in the following ﬁgure, you have to enable the IGMP Proxy ﬁrst.

You can check Enable QoS to improve performance for selected applications. More detailed information for QoS will be introduced in later instruction.

If you choose PPPoE (or Bridging), you will see the option for 802.1Q VLAN Tagging.

802.1Q VLAN Tagging:

802.1Q-compliant switch ports can be conﬁgured to transmit tagged or untagged frames. A tag ﬁeld containing VLAN (and/or 802.1p priority) information can be inserted into an Ethernet frame. If a port has an 802.1Q-compliant device attached (such as another switch), these tagged frames can carry VLAN membership information between switches, thus letting a VLAN span multiple switches. However, it is important for network administrators to ensure ports with non-802.1Q-compliant devices attached are conﬁgured to transmit untagged frames. Many NICs for PCs and printers are not 802.1Q-compliant. If they receive a tagged frame, they will not understand the VLAN tag and will drop the frame. Also, the maximum legal Ethernet frame size for tagged frames was increased in

802.1Q (and its companion, 802.3ac) from 1,518 to 1,522 bytes.

Internet – IGMP Proxy

The Internet Group Management Protocol (IGMP) is an Internet protocol that provides a way for an Internet computer to report its multicast group membership to adjacent routers.

The hosts interact with the system through the exchange of IGMP messages. When you want to conﬁgure IGMP proxy, the system will interact with other routers through the exchange of IGMP messages. However, when acting as the proxy, the system performs the host portion of the IGMP task as follows:

• When being queried, the system will send membership reports to the group.

• When one of the hosts joins a multicast address group which none of other hosts belongs to, the system

will send unsolicited membership reports to that group.

• When the last host in a particular multicast group leaves the group, the system will send a leave group

membership report to the router’s group.

Internet Connection:

This ﬁeld displays the internet connection(s) that set in this router.

The Router implements NAT to make your entire local network appear as a single machine to the Internet. The typical situation is that you have local servers for different services and you want to make them publicly accessible. With NAT applied, it will translate the internal IP addresses of these servers to a single IP address that is unique on the Internet. NAT function not only eliminates the need for multiple public IP addresses but also provides a measure of security for your LAN.

When the router receives an incoming IP packet requesting for accessing your local server, the router will recognize the service type according to the port number in this packet (e.g., port 80 indicates HTTP service and port 21 indicates FTP service). By specifying the port number, the router knows which service should be forwarded to the local IP address that you speciﬁed.

After setting the virtual server, you should modify the ﬁlter rule about the port and service information which you set on the virtual server. Because the ﬁrewall protects the router by ﬁlter rule, you should update the ﬁlter rule after you set up the virtual server.

Virtual Server function allows you to make servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because:

• Your server does not have a valid external IP Address.

• Attempts to connect to devices on your LAN are blocked by the ﬁrewall in this device.

The Virtual Server feature solves these problems and allows Internet users to connect to your servers, as illustrated below:

NB6, NB6W, NB6Plus4W User Guide YML854Rev1 80 www.netcomm.com.au

IP Address seen by Internet Users

Once conﬁgured, anyone on the Internet can connect to your Virtual Servers.

Please note that, in the above picture, both Internet users are connecting to the same IP address, but using different protocols, such as Http://203.70.212.52 and Ftp://203.70.212.52.

To Internet users, all virtual servers on your LAN have the same IP Address. This IP Address is allocated by your ISP. This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use Dynamic DNS feature to allow users to connect to your virtual servers by using a URL, instead of an IP address.

IP addresses can be automatically redirected to local servers conﬁgured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the router redirects the external service request to the appropriate server (located at another internal IP address).

Add New Port Forwarding

To set a virtual server, please open the Virtual Server item from the Advanced setup menu.

To add a new Port Forwarding, please click Add from the Port Forwarding web page.

Virtual Server – DMZ Host

In computer networks, a DMZ (demilitarized zone) is a computer host or small network inserted as a “neutral zone” between a company’s private network and the outside public network. It prevents outside users from getting direct access to a server that has company data. A DMZ is an optional and more secure approach to a ﬁrewall and effectively acts as a proxy server as well.

To close the function of DMZ Host, please click Discarded.

To activate a DMZ host, please click Forwarded to the DMZ host radio button, and enter the IP Address of DMZ host.

Firewall

Internet

Router

with Firewall Protection

PC 1

PC 2

The ﬁrewall is a kind of software that interrupts the data between the Internet and your computer. It is the TCP/IP equivalent of a security gate at the entrance to your company. All data must pass through it, and the ﬁrewall (functions as a security guard) will allow only authorized data to be passed into the LAN.

What the ﬁrewall can do? It can:

• deny or permit any packet from passing through explicitly

• distinguish between various interfaces and match on the following ﬁelds:

• source and destination IP address

• port

To keep track of the performance of IP Filter, a logging device is used. The device supports logging of the TCP/UDP and IP packet headers and the ﬁrst 129 bytes of the packet (including headers) whenever a packet is successfully passed through or blocked, and whenever a packet matches a rule being setup for suspicious packets.

An example for ﬁrewall setup:

This picture shows the most common and easiest way to employ the ﬁrewall. Basically, you can install a packet-ﬁltering router at the Internet gateway and then conﬁgures the ﬁlter rule in the router to block or ﬁlter protocols and addresses. The systems behind the router usually have a direct access to the Internet; however some dangerous services such as NIS and NFS are usually blocked.

For the security of your router, setting the ﬁrewall is an important issue.

Quality of Service

QoS (Quality of Service) is an industry-wide initiative to provide preferential treatment to certain subsets of data, enabling that data to traverse the Internet or intranet with higher quality transmission service.

Quality of Service – Bridge QoS

To classify the upstream trafﬁc by assigning the transmission priority for different users’ data, please use Bridge QoS to prioritize the data transmission.

The Bridge QoS allows you to set the settings based on layer two bridge packets.

Trafﬁc Class Name:

Key in a name as the trafﬁc class for identiﬁcation.

802.1p Priority:

Each incoming packet will be mapped to a speciﬁc priority level, so that these levels may be acted on individually to deliver trafﬁc differentiation. Please choose the number (from 0 to 7, low to high priority) for the 802.1p Priority.

Trafﬁc Priority:

There are three options – Low, Medium, and High that you can choose.

NB6, NB6W, NB6Plus4W User Guide YML854Rev1 92 www.netcomm.com.au

IP Precedence:

The number you choose here decides the type of the IP address processed. No change is the default setting.

IP type of Service:

The system provides some types of service for you to choose. The meaning of each type is the same as the denotation. The default one is No change.

If you set the LAN 802.1p Priority 0 as the trafﬁc condition, choose Low trafﬁc priority for this rule, and set IP Precedence, IP type of service, and WAN 802.1p as no change, after clicking Apply, you will get the result as the ﬁgure in the right column.

Thus when the users’ data matches the trafﬁc condition, the transmission will get a low trafﬁc priority.

The frequency in which the radio links are about to be established. Select one channel that you want from the drop down list.

As an administrator of network, one must search which channels are available and then assign one available channel as the communication channel. All the other clients that match the SSID and pass security authentication can access this device and will use the same channel that you set here.
