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 Modem 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 unsure.
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.

DHCP Configuration
DHCP stands for Dynamic Host Configuration Protocol. Your NB4 has it's DHCP Server enabled by default this means it will assign valid IP addresses to each computer connected to it and will direct those computers to use the NB4 as the gateway to the internet. Having the
DHCP server enabled is the recommended choice.
If you disable the DHCP server in the NB4 you will need to either manually (statically) assign
IP address information to each computer or use another device/computer as DHCP server.
Note: It is not recommended that you have more than one DHCP server enabled on your network.
Server On:
Start IP:
End IP:
Lease time:

Management IP
The Management IP is the IP address of your NB4 on your local network. This IP address is specified on all computers on your network as the Gateway IP address. The Management IP address is also the IP address you type into your browser location bar to configure your NB4.
The Management IP address is usually 192.168.1.1 but you can change it to another suitable number (e.g. 192.168.0.1 or 10.0.0.1 or 172.16.1.1) to suit any existing network devices you already have installed. The NetMask describes how big your network is, the default
255.255.255.0 will allow for 253 computers and generally does not need to be changed unless to suit existing network requirements.
Note: If you change your Management IP address the DHCP server in your NB4 will automatically change the IP address range (DHCP pool) it hands out accordingly.

Most other choices on this screen are personal preference and not critical to getting your connection working.
Note: The Username & Password you need to type in here is for your ISP's account and it will be supplied to you by your ISP.
NAT
Network Address Translation (NAT) is a method of mapping one or more IP addresses and/or
IP service ports into different specified values. Firewall is available in addition to the built-in
NAT mechanism. When working with wide area connections, the first thing you must do is to have the handle of the connection. Once you have the handle for a Connection you must define the PVC and protocol settings for it.

MacFilters
MAC filtering enables rules to be defined which allow or deny data to pass through the Router based on the source and destination MAC address and data type of each data frame.
To access MAC Filters Control, click on Advanced>Advanced Features>MAC Filters .
Usage examples of MAC Filter Rules are: to specify which computers on a network are allowed Internet access; or to determine which particular computers are allowed to access services provided by the Router (the last point is particularly relevant for routers serving
Wireless Networks as it can be used to prevent unauthorised people from attaching themselves to a wireless LAN).
Enable/Disable MAC Filtering
To enable MAC filtering, navigate to the MAC Filter Control Screen and select the Enable
MAC Filters check box.
If the check box is selected, MAC filtering is enabled according to the list of MAC Filter Rules that has been created.
If the box is de-selected, MAC Filtering will not be enabled, even if MAC Filter Rules have been created.
Create MAC Filter Rules
Enter the Source MAC and Destination MAC details. Entering zeros or blanks into the Source or Destination fields enters a null value.
'Protocol' provides the choice of protocol type for the rule.
'Mode' provides the choice of Allow or Deny for the rule.
When all selections are made, click on Add to add the rule to the list of rules. A maximum of
20 MAC Filter Rules can be defined and saved.
To save changes, click on Save Settings on the left-hand menu.

Edit or Delete MAC Filter Rules
To edit an existing MAC Filter Rule, click the radio button adjacent to the Filter Rule name.
The Rule will then appear in the top half of the MAC Filter control screen where it can be edited. When editing is complete, click 'Add' to return the Rule to the list of existing rules.
To delete MAC Filter Rules, click on the 'Delete' tick box; multiple deletions can be made by shift-clicking Delete tick boxes; Select All will select every rule. When the desired selections are made, effect deletion by clicking on Apply.
To save changes, click on Save Settings on the left-hand menu.
Hidden MAC Filter Rules
The MAC filter table contains three hidden rules. These rules are built into the Router to ensure the user does not become locked out by entering a rule which prevents further access to the router.
The first rule allows any and all ARP frames through the system.
The second rule allows all IPv4 frames with the destination MAC address of the bridge to go through.

Multicast
IGMP [=Internet Group Management Protocol] Multicast enables communication between a single sender and multiple receivers on a network. It is used when data needs to be sent from one to many devices. Typical uses might include the updating of mobile personnel from a home office or the periodic publishing of an online newsletter. Multicasting provides efficiencies which enable it to use less network bandwidth than the sending of the same data by other means [e.g. SMTP].
To access Multicasting, click on Advanced>Advanced Features>Multicast.
To enable Multicast, open the multicast screen and select the Enable IGMP Multicast.

Static Routing
If the Router is required to serve more than one network, you will need to set up a Static Route between the networks. Static routing can be used to allow users from one IP domain to access the Internet through the Router in another domain. A Static Route provides the defined pathway that network information must travel to reach the specific host or network which is providing Internet access .
To access the Static Routing controls, click on Advanced>Advanced Features> Static Routing.
Configuring Static Routing:
Choose a Connection: presents list of Saved Connections. Select appropriate connection from list.
The New Destination IP is the address of the remote LAN network or host to which you want to assign a static route. Enter the IP address of the host for which you wish to create a static route here. For a standard Class C IP domain, the network address is the first three fields of the
New Destination IP, while the last field should be 0. The Subnet Mask identifies which portion of an IP address is the network portion, and which portion is the host portion. For a full Class
C Subnet, the Subnet Mask is 255.255.255.0. The Gateway IP address should be the IP address of the gateway device that allows for contact between the Gateway and the remote network or host.
Gateway: IP address refers to the IP address of the near device that is to connect with the remote network or host. If the NB4 is fulfilling this function then its IP address will be entered in this field.

Dynamic Routing
Dynamic Routing makes use of the RIP Protocol to allow the ADSL Router to automatically adjust to physical changes in the network. The NB4, using the RIP protocol, will determine the network packet route based on the fewest number of hops between the Source and the
Destination. The RIP protocol regularly broadcasts routing information to other Routers on the network and is part of the IP Suite.
To access Dynamic Routing click Advanced>Advanced Features>Dynamic Routing.
Enable RIP: if this box is checked, Dynamic Routing is enabled.
Protocol:
Direction: choice is dependent upon the network environment. Most networks support Rip v1. If RIP v1 is selected, routing data will be sent in RIP v1 format. If Rip V2 is selected, routing data will be sent in RIP v2 format using Subnet Broadcasting. If Rip V1 Compatible is selected, routing data will be sent in RIP v2 format using Multicasting.

Port Forwarding
Port Forwarding is necessary because NAT [=Network Address Translation] only forwards traffic from the Internet to the LAN if a specific port mapping exists in the NAT translation table. Because of this, the NAT provides a level of protection for computers that are connected to your LAN. However, this also creates a connectivity problem when you want to make LAN resources available to Internet clients, which you may want to do to play network games or host network applications.
Thus Port Forwarding is necessary to run certain games, chat clients, video-conferencing and other kinds of application. You might also need to configure port-forwarding if you intend to host a web server or mail server that is to be visible outside your LAN.
TIP: In situations where you are hosting a Web Site or, for example, setting up a regular NetMeeting link, it is advisable to consider implementing a Fixed IP address, otherwise the dynamic IP address allocated by DHCP will need to be communicated prior to every user session.

Easy Port Forwarding: Applying Pre-Defined Rules
WAN Connection: refers to the active Connection Profile.
LAN IP: refers to the local Router IP address; the NB4 Default IP is shown in this example.
New IP: If you wish to manually add a LAN client so that you can apply rules to it, click on the New IP Button and enter Host Name and IP Address.
Available pre-defined rules are categorised according to the application type. Click the Radio
Button adjacent to the appropriate Category, and then select the required application name.
Click on the Add button to move the application into the Applied Rules box. In the example shown on the previous page, 'Delta Force' has been selected from the list of Available Rules and is about to be copied to Applied Rules. In the example, this will configure the NB4 ports to use with 'Delta Force' .
To remove a rule from the Applied Rules box, select the Rule and click on the Remove Button.
To save changes, click on Apply, then click on Save Settings.
Advanced Port Forwarding: Creating Custom Rules
If there is no pre-defined Port Forwarding Rule for a particular application, a User Rule can be created which defines the required Port(s), Protocol(s) and Internal Port forwarding rules.
Note than in this section, 'inside port' is indicated by the port map field and corresponds to the port number on the LAN Client. 'Outside ports' refer to the WAN port numbers and are designated by the 'port start' and 'port end' fields.
To create a custom rule you will need to know the specific port number(s) and port type [UDP or TCP] that the application requires. These will be the outside port numbers. Some applications specify a range of ports in which case you will need to know both the starting and ending port numbers in the range, which are mapped by the start port and end port fields.
The Port Map field specifies the internal port that the data will be directed to on the LAN
Client. When dealing with port ranges, the Internal Port (designated by the Port Map field) will be the same as the first port in the range. When you simply want to forward a single port from outside (i.e. WAN side) to inside (i.e. LAN side), then all three fields (Port Start, Port End and
Port Map) will have the same port number.
YML733 Rev1 www.netcomm.com.au
NB4 User Guide
39
To create a New Port Forward Rule:
On the Port Forwarding page shown in the figure above, click on the User radio button, then on the New Button.
Rule Name: enter a name that identifies the rule; for the sake of clarity this will usually be the name of the application. The name must be unique, must not contain spaces and cannot begin with a number.
Protocol: can be either TCP or UDP, or both.
Port start…port end: These will be the same if you are forwarding only a single port. If there is a range, then port start is the first number in the range, and port end will be the last number.
Port Map: this is the port number that the data should be forwarded to on the specified LAN IP
(i.e. the inside port). This is usually the same as the port start figure.
TIP: It is possible to map outside port numbers, or ranges [i.e. port start…port end] to a different inside port numbers [port map] for reasons of security or convenience.
Click 'Apply'
The Port Rule settings defined by this process will then be displayed in a table at the bottom of the Rule Management panel.
If you wish to add more ports to this rule, leave the text name in the Rule Name field and enter the new port settings. Click 'Apply' and the new settings will be added to the list.
Adding Custom Rules to Applied Rules List
When you have assigned all necessary ports to the Rule and they appear in the table, click on the Port Forwarding menu item to return to the main Port Forwarding screen.
User-created rules will be shown in the Available Rules list when the User Category radio button is selected. You can now apply the rule(s) by selecting it and clicking Add. This will add the rule to list of applied rules.

A group of computers that are connected together, allowing 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.
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

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).
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.
A physical access point to a device such as a computer or router, through which data flows into and out of the device.
Plain Old Telephone Service Traditional analog telephone service using copper telephone lines. Pronounced pots. See also PSTN.
See splitter.
Point-to-Point Protocol A protocol for serial data transmission 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.

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.
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.
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.
In a physically separate location. For example, an employee away on travel who logs in to the company’s intranet is a remote user.
Routing Information Protocol The original TCP/IP routing protocol. There are two versions of RIP: version and version II.
Registered Jack Standard-11 The standard plug used to connect telephones, fax machines, modems, etc. to a telephone jack. It is a 6-pin connector usually containing four wires.
Registered Jack Standard-45 The 8-pin plug used in transmitting data over phone lines. Ethernet cabling usually uses this type of connector.
Forwarding data between your network and the Internet on the most efficient route, based on the data’s destination IP address and current network conditions. A device that performs routing is called a router.
See filtering rule, NAT rule.
Secondary Domain Name System (server) A DNS server that can be used if the primary DSN server is not available. See DNS.
Simple Network Management Protocol The TCP/IP protocol used for network management.
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.

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.
A subnet is a portion of a network. The subnet is distinguished 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.
A mask that defines a subnet. See also network mask.
See 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.
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.
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.
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.
The ordinary copper telephone wiring long used by telephone 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
10BASE-T networks, and an even higher grade called Category 5
(CAT 5) is used for 100BASE-T networks. See also 10BASE-T,
100BASE-T, Ethernet.
The direction of data transmission from the user to the Internet.
