Congratulations on becoming the owner of the NB4 ADSL 4-port Modem Router. Your LAN

Do I need a Micro filter?
Do I need a Micro filter?Do I need a Micro filter?
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.

Step 1 - Hardware Installation
To connect your modem, follow the step by step instructions below:
1. Connecting the ADSL cable.
Connect one end of the provided phone cable to the port labeled DSL on the Rear Panel of
the device. Connect the other end to your wall phone jack.
2. Connecting the Ethernet cable.
Connect one end of the ethernet cable to the network port on your PC and the other end of
the cable to the ethernet port of the NB4 ADSL Modem Router.

LAN Setup
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: Enables the DHCP server.
Start IP: Sets the start IP address of the IP address pool.
End IP: Sets the end IP address of the IP address pool.
Lease time: The lease time is the amount of time of a network user will be allowed to
connect with DHCP server. If all fields are 0, the allocated IP address will
be effective forever.
Relay On: Allow PCs on LAN to request IP from other DHCP server.
Relay IP: Sets the other DHCP server IP address.
YML733 Rev1 NB4 User Guide
www.netcomm.com.au 23
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.
IP Address: Private IP address for connecting to a local private network (Default:
192.168.1.1).
Netmask: Netmask for the local private network (Default: 255.255.255.0).
Default Gateway: This field is optional. Enter in the IP address of the router on your
network.
Host Name: Required by some ISPs. If the ISP does not provide the Host name,
please leave it blank.
Domain Name: www.dynsns.org will provide you with a Domain Name. Enter this name
in the "Domain Name" field.
Physical Port: There are five kinds of mode for data transfer (Auto)(10/Half Du-
plex)(10/Full Duplex)(100/Half Duplex)(100/Full Duplex).
Apply: Click Apply to save the changes.
