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 or other device on a WLAN must be Wi-Fi enabled with either a built-in or external wireless adapter.
Laptops — Use a wireless notebook adapter in the PCMCIA slot or a wireless USB adapter.
Desktops — Use a wireless PCI adapter, wireless USB adapter, or compatible product in the PCI slot or USB port, respectively.

Gaming Configuration Guidelines
The following provides information about configuring the SBG901 firewall and DMZ for gaming.
Configuring the Firewall for Gaming
By default, the SBG901 firewall is enabled. As recommended, if you keep the firewall enabled, refer to the game’s documentation to ensure that the necessary ports are open for use by that game.
The pre-defined SBG901 firewall policies affect Xbox LIVE ® as follows:
•
On the
Firewall Web Content Filter Page
, you may need to disable Firewall
Protection and IP Flood Detection.
3 • Basic Configuration 29
B
Configuring Port Triggers
Because the SBG901 has pre-defined port triggers for games using any of the following applications, no user action is required to enable them:
•
ALG for MSN
•
MSN Games by Zone.com
You may need to create custom port triggers to enable other games to operate properly.
To create custom port triggers, see the Advanced Port Triggers Page
.
Configuring a Gaming DMZ Host
CAUTION: The gaming DMZ host is not protected by the firewall. It is open to communication or hacking from any computer on the Internet.
Consider carefully before configuring a device to be in the DMZ.
Some games and game devices require:
•
The use of random ports.
•
The forwarding of unsolicited traffic.
For example, to connect a PlayStation ® 2 for PS2 ® online gaming, designate it as the gaming DMZ host because the ports required vary from game to game. For these games, Motorola recommends configuring the gaming computer or device as a gaming
DMZ device.
To configure a gaming DMZ device, on the Basic DHCP Page :
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.

Advanced Port Forwarding Page
This page allows you to run a publicly accessible server on the LAN by specifying the mapping of TCP/UDP ports to a local PC. This enables incoming requests on specific port numbers to reach web servers, FTP servers, mail servers, etc. so that they can be accessible from the public Internet.
A table of commonly used Port numbers is also displayed on the page for your convenience. The ports used by some common applications are:
•
HTTP: 80
•
FTP: 20, 21
•
Secure Shell: 22
•
Telnet: 23
•
SMTP e-mail: 25
•
SNMP: 161
To map a port, you must enter the range of port numbers that should be forwarded locally and the IP address to which traffic to those ports should be sent. If only a single port specification is desired, enter the same port number in the “start” and “end” locations for that IP address.
6 • Advanced Pages 47

Advanced Port Triggers Page
This page allows you to configure dynamic triggers to specific devices on the LAN. This allows for special applications that require specific port numbers with bi-directional traffic to function properly. Applications such as video conferencing, voice, gaming, and some messaging program features may require these special settings.
The Advanced Port Triggers are similar to Advanced Port Forwarding except that they are not static ports held open all the time. When the Configuration Manager detects outgoing data on a specific IP port number set in the “Trigger Range,” the resulting ports set in the “Target Range” are opened for incoming (sometimes referred to as bi-directional ports) data. If no outgoing traffic is detected on the “Trigger Range” ports for 10 minutes, the “Target Range” ports will close. This is a safer method for opening specific ports for special applications (e.g. video conferencing programs, interactive gaming, file transfer in chat programs, etc.) because they are dynamically triggered and not held open constantly or erroneously left open via the router administrator and exposed for potential hackers to discover.

Advanced DMZ Host Page
This page allows you to specify the default recipient of WAN traffic that NAT is unable to translate to a known local PC. The DMZ (De-militarized Zone) hosting (also commonly referred to as “Exposed Host”) can also be described as a computer or small sub-network that is located outside the firewall between the trusted internal private LAN and the untrusted public Internet. It 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
You may configure one PC to be the DMZ host. This setting is generally used for PCs using problem applications that use random port numbers and do not function correctly with specific port triggers or the port forwarding setups mentioned earlier. If a specific
PC is set as a DMZ Host, remember to set this back to 0 when you are finished with the needed application, since this PC will be effectively exposed to the public Internet, though still protected from Denial of Service (DoS) attacks via the Firewall.
Setting Up the DMZ Host
1.
Enter the computer’s IP address.
2.
Click Apply to activate the selected computer as the DMZ host.
Advanced Routing Information Protocol Setup
Page
This page allows you to configure Routing Information Protocol (RIP) parameters related to authentication, destination IP address/subnet mask, and reporting intervals. RIP
6 • Advanced Pages 49
B automatically identifies and uses the best known and quickest route to any given destination address. To help reduce network congestion and delays, the Advanced RIP setup is used in WAN networks to identify and use the best known and quickest route to given destination addresses.
RIP is a protocol that requires negotiation from both sides of the network (i.e., CMRG and CMTS). The ISP would normally set this up to match their CMTS settings with the configuration in the CMRG.
Note: RIP messaging will only be sent upstream when running in Static
IP Addressing mode on the Basic Setup page. You must enable Static
IP Addressing and then set the WAN IP network information! RIP is normally a function that is tightly controlled via the ISP. RIP
Authentication Keys and IDs are normally held as secret information from the end user to prevent unauthorized RIP settings.

Firewall Pages
The SBG901 Firewall Pages allow you to configure the SBG901 firewall filters and firewall alert notifications. The SBG901 firewall protects the SBG901 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 the Firewall Pages.
You can click any Firewall submenu option to view or change the firewall configuration information for that option.
For information about how the firewall can affect gaming, see Gaming Configuration
.
The predefined policies provide outbound Internet access for computers on the SBG901
LAN. The SBG901 firewall uses
stateful-inspection to allow inbound responses when
there already is an outbound session running that corresponds to the data flow. For example, if you use a web browser, outbound HTTP connections are permitted on port
80. Inbound responses from the Internet are allowed because an outbound session is established.
When required, you can configure the SBG901 firewall to allow inbound packets without first establishing an outbound session. You also need to configure a port forwarding entry on the

Parental Control User Setup Page
This page is the master page. Each user is linked to a specified time access rule, content filtering rule, and login password to get to the filtered content. You may also specify a user as a “trusted user,” which means that person will have access to all Internet content regardless of the filters that you define. You can use the Trusted User checkbox as a simple override to grant a user full access, while storing all of the filtering settings for easy availability.
You can also enable Internet session duration timers, which set a limited amount of time for Internet access from the rules you select. The user must enter their password only the first time to access the Internet. It is not necessary to enter the password each time a new web page is accessed. In addition, there is a password inactivity timer. If there is no Internet access for the specified time in minutes, the user must login again. These timed logins ensure that a specific user uses the Internet gateway appropriately.

Sets the shared secret for the RADIUS connection. The key is a 0 to 255 character ASCII string.
Sets the WPA Group Rekey Interval in seconds. Set to zero to disable periodic rekeying.
The re-authentication interval is the amount of time the wireless router can wait before re-establishing authentication with the CPE.
WEP Encryption enables or disables Wired Equivalent Privacy encryption.
The WEP protocol uses Shared Key Authentication, which is an Authentication protocol where the CPE sends an authentication request to the access point. Then, the access point sends a challenge text to the CPE.
The CPE uses either the 64-bit or 128-bit key to encrypt the challenge text and sends the encrypted text to the access point. The access point will decrypt the encrypted text and then compare the decrypted message with the original challenge text. If they are the same, the access point will let the CPE connect; if it doesn’t match, then the access point does not let the CPE connect.

Setting Up Your Wireless LAN
You can use the SBG901 as an access point for a wireless LAN (WLAN) without changing its default settings.
To enable security for your WLAN, you can do the following on the SBG901:
•
Encrypt wireless LAN transmissions
•
Restrict wireless LAN access to further prevent unauthorized WLAN intrusions using the
Wireless 802.11 Access Control Page
CAUTION: Never provide your SSID, WPA or WEP passphrase, or WEP key to anyone who is not authorized to use your WLAN.
Connect at least one computer to the SBG901 Ethernet port to perform configuration.
Do not attempt to configure the SBG901 over a wireless connection.
You need to configure each wireless client (station) to access the SBG901 LAN as
described in Installing Wireless Clients .
Another step to improve wireless security is to place wireless components away from windows. This decreases the signal strength outside the intended area.

Encrypting Wireless LAN Transmissions
To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt your wireless transmissions. Choose one:
Encrypting Wireless LAN Transmissions
Configure on the SBG901 Required on Each Wireless Client
If all of your wireless clients support Wi-Fi Protected Access
(WPA), Motorola recommends configuring WPA on the SBG901
If you use a local pre-shared key (WPA-PSK) passphrase, you must configure the identical passphrase to the SBG901 on each wireless client.
Home and small-office settings typically use a local passphrase.
Otherwise, configure WEP on the
SBG901
You must configure the identical WEP key to the
SBG901 on each wireless client.
If all of your wireless clients support WPA encryption, Motorola recommends using WPA instead of WEP because WPA:
•
Provides much stronger encryption and is more secure
•
Provides authentication to ensure that only authorized users can log in to your WLAN
•
Is much easier to configure
•
Uses a standard algorithm on all compliant products to generate a key from a textual passphrase
•
Will be incorporated into the new IEEE 802.11i wireless networking standard
For new wireless LANs, Motorola recommends purchasing client adapters that support
WPA encryption.

A type of cable consisting of a center wire surrounded by insulation and a grounded shield of braided (coax) wire. The shield minimizes electrical and radio frequency interference. Coaxial cable has high bandwidth and can support transmission over long distances.
Dynamic Host Configuration Protocol server — dynamically assigns
IP addresses to client hosts on an IP network. DHCP eliminates manually assigning static IP addresses by “leasing” an IP address and subnet mask to each client. It enables the automatic reuse of unused IP addresses.
The SBG901 is simultaneously a DHCP client and a DHCP server.
A DHCP server at the cable system headend assigns a public IP address to the SBG901 and optionally to clients on the SBG901 LAN.
The SBG901 contains a built-in DHCP server that assigns private IP addresses to clients.
A “de-militarized zone” is one or more hosts logically located between a private LAN and the Internet. A DMZ prevents direct access by outside users to private data. (The term comes from the geographic buffers located between some conflicting countries, such as North and South Korea.) In a typical small DMZ configuration, the
DMZ host receives requests from private LAN users to access external web sites and initiates sessions for these requests. The
DMZ host cannot initiate a session back to the private LAN. Internet users outside the private LAN can access only the DMZ host. You can use a DMZ to set up a web server or for gaming without exposing confidential data.
In a cable data network, this is the direction of the data received by the computer from the Internet.
A security software system on the SBG901 that enforces an access control policy between the Internet and the SBG901 LAN.

DEFINITION
A device that enables communication between networks using different protocols. The SBG901 enables up to 245 computers supporting IEEE 802.11b/g or Ethernet to share a single broadband
Internet connection.
Internet Service Provider
The Media Access Control address is a unique, 48-bit value permanently saved in ROM at the factory to identify each Ethernet network device. It is expressed as a sequence of 12 hexadecimal digits printed on a label on the bottom of the SBG901. You need to provide the HFC MAC address to the Internet Service provider. Also called an Ethernet address, physical address, hardware address, or
NIC address.
Network Address Translation is an Internet standard for a LAN to use one set of IP addresses for internal traffic and a second set of IP addresses for external traffic.
A pass-through client on the SBG901 LAN obtains its public IP address from the Internet Service provider’s DHCP server.
A feature that enables one port (source) on the SBG901 to be copied to another port (destination) to be studied. The destination mirrors the transmitted (from) or received (to) data on the source port to enable the person managing the network to monitor activity.
A mechanism that allows incoming communication with specified applications. Primarily used for gaming applications.
An IP address assigned to a computer on the SBG901 LAN by the
DHCP server on the SBG901 for an address-specified lease time.
Private IP addresses are used by the SBG901 LAN only; they are invisible to devices on the Internet. See also public IP address.
The IP address assigned to the SBG901 by the Internet Service provider. A public IP address is visible to devices on the Internet. See also private IP address.
Quality of service describes the priority, delay, throughput, and bandwidth of a connection.
The most common type of connector for household or office phones.
An 8-pin modular connector; this is the most common connector type for 10Base-T or 100Base-T Ethernet networks.

TERM stateful-inspection subscriber synchronous upstream
Wireless Cable Modem
Gateway
WPA
DEFINITION
A type of firewall that tracks each connection, traversing all firewall interfaces to ensure validity. In addition to examining the source and destination in the packet header based on static rules, a stateful inspection firewall:
•
•
•
•
Examines packet headers via the context established by previous packets that traversed the firewall
Monitors the connection state and saves it in a table
Closes ports until a connection to a specific port is requested
May examine the packet contents up through the application layer to determine more than just the source and destination
A stateful inspection firewall is more advanced than a static filter firewall.
A home or office user who accesses television, data, or other services from an Internet Service provider.
The SBG901 uses synchronous timing for upstream data transmissions. The CMTS broadcasts timing messages that bandwidth is available. The SBG901 reserves data bytes requiring x number of mini-slots. The CMTS replies that it can receive data at a specified time (synchronized). At the specified time, the SBG901 transmits the x-number of data bytes.
In a cable data network, upstream describes the direction of data sent from the subscriber’s computer through the cable modem to the CMTS and the Internet.
The Motorola SURFboard Wireless Cable Modem Gateway is a single device that combines a cable modem, router, Ethernet switch, wireless access point, and DHCP server for SOHO or SME use.
Wi-Fi Protected Access (WPA) encryption, as described on the Wi-Fi
Alliance web page: http://www.wifialliance.org. It is a far more robust form of encryption than WEP. Motorola recommends using WPA if all of your client hardware supports WPA.
