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.
Laptop PCs — Use a wireless notebook adapter in the PCMCIA slot or a wireless USB adapter.
Desktop PCs — Use a wireless PCI adapter, wireless USB adapter, or compatible product in the
PCI slot or USB port, respectively.

wireless connection.
Your maximum wireless operation distance depends on the type of materials through which the
signal must pass and the location of your SBG901 and clients (stations). Motorola cannot
guarantee wireless operation for all supported distances in all environments.

Firewall
The SBG901 firewall protects the SBG901 LAN from undesired attacks and other intrusions from
the Internet. It provides an advanced, integrated stateful-inspection
detection, session tracking, and denial-of-service attack prevention. The firewall:
firewall supporting intrusion
DMZ
• Maintains state data for every TCP/IP
• Monitors all incoming and outgoing packets
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 the Firewall Pages
A de-militarized zone (DMZ) is one or more computers logically located outside the firewall
between an SBG901 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:
• If needed, you can configure additional port triggers on the Advanced Port Triggers 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. To prevent unauthorized
eavesdropping of data transmitted over your LAN, you must enable wireless security. The default
SBG901 settings neither provide security for transmitted data nor protect network data from
unauthorized intrusions.
The SBG901 provides the following wireless security measures, which are described on the
Wireless Pages
To prevent unauthorized eavesdropping, you must encrypt data transmitted over the wireless
interface using one of the following:
• If all of your wireless clients support Wi-Fi Protected Access (WPA or WPA2) encryption,
Motorola recommends using WPA2. Otherwise, configure a Wired Equivalency Privacy
(WEP) key on the SBG901 and each WLAN client.
• To protect the wireless LAN from unauthorized intrusions (see Setting Up Your Wireless
LAN), you can do one or both of the following:
Restrict WLAN access to computers having known MAC addresses
Enable closed network operation by disabling SSID broadcasting
.
Port Forwarding
The SBG901 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 video conferencing, 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. You 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
Advanced Port Forwarding Page.
