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 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 wireless LAN requires an adapter described in “Optional Accessories”:
Laptop PCs Use a Motorola PCC11b Wireless Card in the PCMCIA slot.
Desktop PCs Use a Motorola USB11b Wireless Adapter to connect the USB port.
Sample wireless network connections
To set up the SBG900, on a computer wired to the SBG900 over Ethernet or USB, perform the procedures in “Setting Up the Wireless LAN
To set up each wireless client (station):
1 Insert the

Wired Ethernet LAN

Each computer on the 10/100Base-T Ethernet LAN requires an Ethernet network interface card (NIC) and driver software installed. Because the SBG900 Ethernet port supports auto-MDIX, you can use straight-through or cross-over cable to connect a hub, switch, or computer. Use category 5 cabling for all Ethernet connections.
The physical wiring arrangement has no connection to the logical network allocation of IP addresses.

Security

The SBG900 provides:
• A firewall to protect the SBG900 LAN from undesired attacks over the Internet
• Security measures to prevent eavesdropping of wireless data
Network Address Translation (NAT) provides some security because the IP addresses of SBG900 LAN computers are not visible on the Internet.
The logical network diagram does not necessarily correspond to the network cabling. A full discussion of network security is beyond the scope of this document.

Firewall
The SBG900 firewall protects the SBG900 LAN from undesired attacks and other intrusions from the Internet. It provides an advanced integrated stateful-inspection firewall supporting intrusion detection, 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”.

DMZ
A de-militarized zone (DMZ) is one or more computers logically located outside the firewall between an SBG900 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 information, see Gaming Configuration Guidelines.

Port Triggering

When you run a PC application that accesses the Internet, it typically initiates communications with a computer on the Internet. In some applications, especially gaming, the computer on the Internet also initiates communications with your PC. Because NAT does not normally allow these incoming connections to occur, the SBG900 supports port triggering.
The SBG900 is preconfigured with port triggering for common applications. You can also configure additional port triggers if needed on the Gateway > PORT TRIGGERS — custom Page.

Wireless Security

Because wireless LAN signals are transmitted using radio signals, it may be possible for your neighbor or someone else you do not want accessing 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 following wireless security measures:
• Restrict access to computers having the same unique network name as the SBG900
• Encrypt data transmitted over the wireless interface 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 broadcasting to enable closed network operation, the SBG900 does not transmit the network name (ESSID). This provides additional protection because only wireless stations configured with your network name can communicate with the SBG900. Closed network operation is an enhancement of the IEEE 802.11b standard.
For information about configuring a wireless security, see “Setting Up the Wireless LAN”.

Port Forwarding

Port forwarding is the configuration of SBG logical data ports for applications having special network requirements.
The SBG900 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. 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
Teln et 23
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. 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 Gateway > PORT FORWARDING — config Page.

Virtual Private Net work s

The SBG900 allows multiple tunnel VPN pass-through operation to securely connect remote computers over 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 client or gateway and ANX certified IPSec stacks

Session Log The Session Log shows data sessions that have occurred and tracked by the Firewall. To
enable logging of sessions, the Enable Session Log option must be selected in the Firewall Logs Config Page. A firewall policy must be in effect for session events to be generated. If the firewall policy is set to None then no new session entry will be generated.
The log entries correspond to data sessions that have occurred in the device that are authorized by the normal firewall filters. Usually, this log shows the history of normal data traffic. Though a session may be terminated early by the firewall due to policy or session change, or if the session is later determined by the firewall to be an intrusion attack.
Blocking Log The Blocking Log shows firewall blocking events. To enable logging of blocking events, the
Enable Blocking Log option must be selected in the Firewall Logs Config Page. A firewall policy must be in effect for blocking events to be generated. If the firewall policy is set to None then no new blocking entry will be generated.
The log entries correspond to firewall blocking events that occur when unauthorized inbound or outbound data packets are detected. Unauthorized data packets are those that use protocols and/or ports that are not explicitly allowed by the current firewall policy. In addition, data packets that are determined to be invalid due to session time-outs or reassembly time-outs are also blocked.
Intrusion Log The Intrusion Log shows the intrusions attempts that have occurred and stopped by the
firewall. To enable logging of intrusion events, the Enable Intrusion Log option must be selected in the Firewall Logs Config Page. A firewall policy must be in effect for intrusion events to be generated. If the firewall policy is set to None then no new intrusion entry will be generated.
The log entries correspond to intrusion attacks that have been detected and stopped by the firewall. The firewall is capable of detecting several well-known intrusion tactics that is used to attack a network device. This log is a history of those intrusion events.
Blacklist The Blacklist Log shows the IP addresses that have been determined by the firewall to have
breached the firewall policy of the SBG. A firewall policy must be in effect for blacklist entries to be generated. If the firewall policy is set to None then no new blacklist entry will be generated.
Once an IP address has been blacklisted, the firewall will block all traffic to and from that IP address for 24 hours or when the SBG is rebooted. The user can manually clear the blacklist by pressing the Clear button on the Blacklist Page. Clearing the blacklist table also allows normal traffic to flow between the SBG and the formerly blacklisted entries

1 Reserve a private IP address for the computer or game device MAC address.
2 Designate the device as a DMZ device.
You can reserve IP addresses for multiple devices, but only one can be designated as the gaming DMZ at once.

Gateway > PORT TRIGGERS — predefined Page

When you run a PC application that accesses the Internet, it communicates with a computer on the Internet. In some applications, especially gaming, the computer on the Internet also communicates with your PC. Because NAT does not normally allow these incoming connections, the SBG900 supports port triggering.
The SBG900 is preconfigured with port triggering for common applications. You can also configure additional port triggers if needed. Configuring port triggers for an application requires:
• The application transport protocol — TCP or UDP
• The application port number
You can use the default values for the remaining parameters.
Only one PC at a time connected to the SBG900 can use an application requiring port triggering. Use this page to view predefined port triggers:

Setting Up the Wireless LAN

You can use the SBG900 as an access point for a wireless LAN without changing its default settings.
Caution!
The default SBG900 settings provide no wireless security. After your wireless LAN is operational, be sure to enable security as described in “Setting Up the Wireless LAN” in the SBG900 User Guide.
To enable security for your SBG900 wireless LAN, you can do the following on the SBG900:
To
Configure an Extended Service Set Identifier (ESSID) and enable closed network operation
Enable Wired Equivalent Privacy (WEP) encryption and configure a WEP key
Restrict access to computers with known MAC addresses

”
.
Caution!
Never provide the ESSID or WEP key to anyone who is not authorized to use your wireless LAN.
For descriptions of all wireless configuration fields, see “Wireless Pages in the SBG900 Setup Program”.
Another common-sense step to improve wireless security is to place wireless components away from windows. This decreases the signal strength outside the intended area.
