Wireless LAN
Wireless communication occurs over radio waves rather than a wire. Like a cordless telephone, a WLAN uses
radio signals instead of wires to exchange data. A wireless network eliminates the need for expensive and
intrusive wiring to connect computers throughout the home or office. Mobile users can remain connected to the
network even when carrying their laptop to different locations in the home or office.
Each computer on a WLAN requires a wireless adapter shown in “Optional Accessories”:
Laptop PCs Use a Motorola Wireless Notebook Adapter or compatible product in the PCMCIA slot.
Desktop PCs Use a Motorola Wireless PCI Adapter, Wireless USB Adapter, or compatible product in the PCI slot or
USB port, respectively.

Setup Program
To set up the SBG940, on a computer wired to the SBG940 over Ethernet or USB, perform the procedures in
“Setting Up Your Wireless LAN”. Do not attempt to configure the SBG940 over a wireless connection.
Your maximum wireless operation distance depends on the type of materi als through which the signal must pass
and the location of your antennas and clients (stations). Motorola cannot guarantee wireless operation for all
supported distances in all environments.
An optional Motorola high gain antenna can improve wireless performance. For information abo ut available
optional antennas for your SBG940, contact your cable provider.

Security
The SBG940 provides:
• A firewall to protect the SBG940 LAN from undesired attacks over the Internet
• For wireless transmissions, data encryption and network access control
Network Address Translation (NAT) provides some security because the IP addresses of SBG940 LAN computers
are not visible on the Internet.

Firewall
The SBG940 firewall protects the SBG940 LAN from undesired attacks and other intrusions from the Internet. It
provides an advanced integrated stateful-inspection firewall supporting intrusion de tection, session tracking, and
denial-of-service attack prevention. The firewall:
• Maintains state data for every TCP/IP session on the OSI network and transport layers
• Monitors all incoming and outgoing packets, applies the firewall policy to each one, and screens for improper
packets and intrusion attempts
• Provides comprehensive logging for all:
— User authentications
— Rejected internal and external connection requests
— Session creation and termination
— Outside attacks (intrusion detection)
You can configure the firewall filters to set rules for port usage. For information about choosing a predefined
firewall policy template, see “Setting the Firewall Policy”.

Configuration: Basic Gateway TCP/IP Wireless USB
DMZ
A de-militarized zone (DMZ) is one or more computers logically located outside the firewall between an SBG940
LAN and the Internet. A DMZ prevents direct access by outside users to private data.
For example, you can set up a web server on a DMZ computer to enable outside users to access your website
without exposing confidential data on your network.
A DMZ can also be useful to play interactive games that may have a problem running through a firewall. You can
leave a computer used for gaming only exposed to the Internet while protecting the rest of your network. For more
information, see “Gaming Configuration Guidelines”.
Port Triggering
When you run an application that accesses the Internet, it typically initiates communications with a computer on
the Internet. For some applications, especially gaming, the computer on the Internet also initiates communications
with your computer. Because NAT does not normally allow these incoming connections:
• The SBG940 has preconfigured port triggers for common applications.
• If needed, you can configure additional port triggers on the Gateway > PORT TRIGGERS — custom Page.
Wireless Security
Because WLAN data is transmitted using radio signals, it may be possible for an unauthorized person to access
your WLAN unless you prevent them from doing so. T o prevent unauthorized eavesdropping of data transmitted
over your LAN, you must enable wireless security. The default SBG940 settings neither provide security for
transmitted data nor protect network data from unauthorized intrusions.
The SBG940 provides the following wireless security measures, which are described in “Setting Up Your Wireless
LAN”:
• To prevent unauthorized eavesdropping, you must encrypt data transmitted over the wireless interface using
one of:
— If all of your wireless clients support Wi-Fi
WPA (see “Configuring WPA on the SBG940” and “Configuring a Wireless Client for WPA”).
— Otherwise, configure a Wired Equivalency Privacy (WEP) key on the SBG940 and each WLAN client
(see “Configuring WEP on the SBG940” and “Configuring a Wireless Client for WEP”).
®
Protected Access (WPA) encryption, we recommend using
• To protect LAN data from unauthorized intrusions, you can restrict WLAN access to computers having one or
both of:
— Known MAC addresses (see “Configuring a MAC Access Control List on the SBG940”)
— The same u niq ue ne two rk nam e (ESSID) as the SBG940 (see “Configuring the Wireless Network Name
on the SBG940” and “Configuring a Wireless Client with the Network Name (ESSID)”)
Restricting access to computers having the same network name is also called “disabling ESSID broadcasting” or
“enabling closed network operation.”
SBG940 User Guide 14
Overview Installation Troubleshooting Contact FAQ Specifications Glossary License
Configuration: Basic Gateway TCP/IP Wireless USB
Port Forwarding
The SBG940 opens logical data ports when a computer on its LAN sends data, such as e-mail messages or web
data, to the Internet. A logical data port is different from a physical port, such as an Ethernet port. Data from a
protocol must go through certain data ports.
Some applications, such as games and videoconferencing, require multiple data ports. If you enable NAT, this can
cause problems because NAT assumes that data sent through one port will return to the same port. Y ou may need
to configure port forwarding to run applications with special requirements.
To configure port forwarding, you must specify an inbound (source) port or range of ports. The inbound port opens
only when data is sent to the inbound port and closes again after a specified time elapses with no data sent to it.
You can configure up to 32 port forwarding entries using the Gateway > PORT FORWARDING — config Page.
Virtual Private Networks
The SBG940 supports multiple tunnel VPN pass-through operation to securely connect remote computers over
the Internet. The SBG940:
• Is compatible with Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP)
• Is fully interoperable with any IPSec client or gateway and ANX certified IPSec stacks
