Wireless LAN
Wireless communication occurs over radio waves rather than a wire. Like a cordless telephone, a wireless LAN
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 off ice. Mobile users can remain connected to the
network even when carrying their laptop to dif ferent locations in t he hom e or office.

Security
The SBG900 provides:
• A firewall to protect the SBG900 LAN from undesi red attacks over the In ter net
• Security measures to prevent eavesdropping of wireless data
Network Address Translation ( NAT) provides some sec urit y bec ause the I P address es of SBG900 LA N computers

Firewall
The SBG900 firewall prote cts the SBG900 LAN from undesired attacks and other intrusions from the Internet. It
provides an advanced i ntegrated stateful-inspection firewall supporting intrusion detection, session tracking, and
denial-of-service attack pr evention. The firewall :
• Maintains state data for ever y TCP/IP session on the OSI network and transport layers
• Monitors all incoming and outgoing packets, applies the firewall p oli cy 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 (intrusi on detection)
You can configure the firewall filters to set rules for port usage and to block specific IP domai ns and network s. For
information about choosing a predefined fir ewall policy template, see “Setting the Firewall Policy”.

DMZ
A de-militarized zone (DMZ) is one or more computers logically located outsid e the f irewall between an SBG900
LAN and the Internet. A DMZ prevent s direct access by outside users to private data.
For example, you can set up a web server on a DM Z com puter to enable outside users to access your websit e
without exposing confidential data on your network.
A DMZ can also be useful to play interactive games that may have a probl em running through a firewall. You can
leave a com puter used for gaming only exposed to the Inter net while prot ecting the rest of your network. For m ore
information , see Gaming Configuration Guidelines.
Port Triggering
When you run a PC application that acce sses the In ternet , it typi cally initiat es co mmunicati ons with a computer on
the Internet. In some applications, especially gaming, th e com puter on the Internet also i nitiates communications
with your PC. Because NAT does not normally allow these incoming connections to occur, the SBG900 supports
port triggerin g.
The SBG900 is preconfigured with port triggering for common applications. You can also configure additi onal port
triggers if needed on the Gateway > PORT TRIGGERS — custom Page.
Wireless Security
Because wireless LAN signals are transmitted using radio signals, it ma y be possible for your neighbor or
someone else you do not want access your wireless LAN. You need to limit access to only the intended persons.
To prevent unauthorized eavesdropping of data transmitted over the wireless LAN, you must enable wireless
security. The default SBG900 settings provide no security for transmitted data.
The SBG900 enables you to use the foll owing wireless security measures:
• Restrict acces s to computers having the same uniq ue network name as the SBG900
• Encrypt data transm itted over the wireles s int erface by configuring a Wired Equivalency Privacy (WEP) key
on the SBG900 and wireless LAN clients (stations)
• Define a MAC access control list to restrict wireless LAN access to clients based on the MAC address.
If you disable ESSID br oadca sting to enab le closed networ k oper ation , the SBG900 doe s not tr ansmit the net wor k
name (ESSID). This provide s additional protection because only wireless stations configured wi th your network
name can communicate with th e SBG90 0. Cl osed network operation is an enhancement of the IEEE 802.11 b
standard.
For information about configuring a wireless security, see “Setting Up the Wireless LAN”.

Port Forwarding
Port forwarding is t he configuration of SBG logic al data ports for app li cations having special network
requirements.
The SBG900 opens logical dat a ports when a computer on it s LAN sends data, such as e-mail mes sages or web
data, to the Inter net. 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. Here are the data ports used by some protocols:
Protocol Port
FTP 20, 21
HTTP 80
NTP 123
Secure Shell 22
SMTP e-mail 25
Telnet 23
Some application s, such as games and vi deoconf ere ncing, requir e multiple dat a ports. If you enable NAT , this can
cause problems beca use NAT assumes that data sent t hrough on e por t will r eturn t o the sam e port . You may need
to configure port forwarding to run applications with special requirements.
T o conf i gure port forwarding , you must specify an inbound (so urce) por t or range of port s. The in bound 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 Net work s
The SBG900 allows multiple tunnel VPN pass-through operat ion to securely connect remote computers ove r the
Internet through the SBG900. The SBG900:
• Is compatible with Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP)
• Is fully interoperable with any IPSec cli ent or gateway and ANX certified I PSec stacks
