Overview
Thank you for purchasing the NetComm NB1 ADSL/ADSL2 Modem Router. Net-
Comm brings you the Next Generation of ADSL technology with ADSL-2*, which
boosts ADSL’s performance, improves interoperability, and supports new applica-
tions, services and deployment conditions.
NetComm’s implementation of ADSL-2* and ADSL-2+* ensures that the NB1 oper-
ates with existing ADSL services while delivering optimal performance in all modes
of operation. Powered by the latest ADSL-2* TI chipset, NetComm’s NB1 increases
downstream data rates by up to 50% (12Mbps) and 100% (25Mbps) for ADSL2
Plus* mode ensuring that you can surf the net or down load your files quicker than
ever before.
Security is a key issue with Broadband users and NetComm’s NB1 does not leave
you exposed. Employing the latest Active Firewall technology, the NB1 checks every
packet of data that comes in ensuring your defences are rock-solid against hackers,
unauthorised entries, probes and even Denial of Service attacks. What’s more, the
NB1 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.
The NB1 delivers the connection versatility needed to cater for today’s ADSL users.
You can simply attach the NB1 to a single PC via the Ethernet port. Alternatively,
should you wish to share your Internet connection, the NB1 is equipped with an
in-built Router which will support multiple PCs with the addition of device such as a
NetComm 5- or 8-port Network Switch.
The NB1’s Port Forwarding and UPnP functions have made it easier for today’s Inter-
net users to configure and setup the myriad of Network Port Rules needed by Inter-
net applications such as On-Line Gaming, Peer-To-Peer file sharing and Messenger
services to operate. NB1 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 NB1 introduces a QoS (Quality of Service) feature that gives you
control over which types of outgoing data are given priority by the router. With QoS
you can tailor your router settings to ensure that you can keep gaming or browsing
even though your upstream bandwidth may be saturated by applications such as
Peer-To-Peer file sharing.
* 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.
Note that due to the fact that the NB1 is an adaption of the NB5 multi-port router, several functions belonging to
the NB5 including LAN Groups are still represented by screens in the NB1 firmware. These screens to not have a
corresponding function in this model which will be noted in the manual where applicable.
