See the sample Firewall help page shown below: You can use the Windows scroll bar to view additional items on the help screens. Gaming Configuration Guidelines The following provides information about configuring the SBG941 firewall and DMZ for gaming. Configuring the Firewall for Gaming By default, the SBG941 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 SBG941 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. Configuring Port Triggers Because the SBG941 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 4 • Basic Configuration 21
B 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.

B Advanced IP Filtering Page This page allows you to define which local PCs will be denied access to the SBG941 WAN. You can configure IP address filters to block Internet traffic to specific network devices on the LAN by entering starting and ending IP address ranges. Note that you only need to enter the LSB (Least-significant byte) of the IP address; the upper bytes of the IP address are set automatically from the SBG941 Configuration Manager’s IP address. The Enabled option allows you to store filter settings commonly used but not have them active. Field Descriptions for the Advanced IP Filtering Page Field Description Start Address Enter the starting IP address range of the computers for which you want to deny access to the SBG941 WAN. Be sure to only enter the least significant byte of the IP address. End Address Enter the ending IP address range of the computers you want to deny access to the SBG941 WAN. Be sure to only enter the least significant byte of the IP address. Enabled Activates the IP address filter, when selected. Checkmark Enabled for each range of IP addresses you want to deny access to the SBG941 WAN. When done, click Apply to activate and save your settings. 7 • Advanced Pages 35
B Advanced MAC Filtering Page This page allows you to define up to twenty Media Access Control (MAC) address filters to prevent PCs from sending outgoing TCP/UDP traffic to the WAN via their MAC addresses. This is useful because the MAC address of a specific NIC card never changes, unlike its IP address, which can be assigned via the DHCP server or hard-coded to various addresses over time. Field Descriptions for the Advanced MAC Filtering Page Field Description MAC Addresses Media Access Control address — a unique set of 12 hexadecimal digits assigned to a PC during manufacturing. Setting a MAC Address Filter 1. Enter the MAC address in the MAC Addresses field for the PC you want to block. 2. Click Add MAC Address. 3. Repeat above steps for up to twenty MAC addresses. 7 • Advanced Pages 36
B Advanced Port Filtering Page This page allows you to define port filters to prevent all devices from sending outgoing TCP/UDP traffic to the WAN on specific IP port numbers. By specifying a starting and ending port range, you can determine what TCP/UDP traffic is allowed out to the WAN on a per-port basis. Note: The specified port ranges are blocked for ALL PCs, and this setting is not IP address or MAC address specific. For example, if you wanted to block all PCs on the private LAN from accessing HTTP sites (or “web surfing”), you would set the “Start Port” to 80, “End Port” to 80, “Protocol” to TCP, checkmark Enabled, and then click Apply. Field Descriptions for the Advanced Port Filtering Page Field Description Start Port Enter the starting port number. End Port Enter the ending port number. Protocol Select TCP, UDP, or Both from the drop-down list. Enabled Checkmark for each port that you want to activate the IP port filters. 7 • Advanced Pages 37
B 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. 7 • Advanced Pages 38
B 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, 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. Field Descriptions for the Advanced Port Triggers Page Field Description Trigger Range Start Port The starting port number of the Port Trigger range. End Port The ending port number of the Port Trigger range. Target Range Start Port The starting port number of the Port Trigger range. End Port The ending port number of the Port Trigger range. 7 • Advanced Pages 39
B Field Description Protocol Select TCP, UDP, or Both from the drop-down list. Enable Select checkbox to activate the IP port triggers. 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 Gaming Configuration Guidelines. 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 7 • Advanced Pages 40
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. Field Descriptions for the Advanced RIP Setup Page Field Description RIP Enable Enables or disables the RIP protocol. This protocol helps the router dynamically adapt to the changes in the network. RIP is now considered obsolete since newer routing protocols, such as OSPF and ISIS, have been introduced. RIP Authentication If this field is enabled, a plain text password or a shared key authentication is added to the RIP packet in order for the CPE and the wireless router to authenticate each other. RIP Authentication Key Used to encrypt the plain text password that is enclosed in each RIP packet. If you are using the shared key authentication in RIP, you will need to provide a key. RIP Authentication Key ID An unsigned 8-bit field in the RIP packet. This field identifies the key used to create the authentication data for the RIP 7 • Advanced Pages 41
B Field Description packet, and it also indicates the authentication algorithm. RIP Reporting Interval Determines how long before a RIP packet is sent out to the CPE. RIP Destination IP Address Location where the RIP packet is sent to update the routing table in your CPE. RIP Destination IP Subnet Mask Specifies which CPE you want to receive the RIP packet. 7 • Advanced Pages 42
B 8 Firewall Pages The SBG941 Firewall Pages allow you to configure the SBG941 firewall filters and firewall alert notifications. The SBG941 firewall protects the SBG941 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 Guidelines. The predefined policies provide outbound Internet access for computers on the SBG941 LAN. The SBG941 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 SBG941 firewall to allow inbound packets without first establishing an outbound session. You also need to configure a port forwarding entry on the Advanced Port Forwarding Page or a DMZ client on the Advanced DMZ Host Page. 8 • Firewall Pages 43
B Firewall Web Content Filter Page This page allows you to configure the firewall by enabling or disabling various Web filters related to blocking or exclusively allowing different types of data through the Configuration Manager from the WAN to the LAN. Java Applets, Cookies, ActiveX controls, popup windows, and Proxies can be blocked from this page. Firewall Protection turns on the Stateful Packet Inspection (SPI) firewall features. Block Fragmented IP packets prevent all fragmented IP packets from passing through the firewall. Port Scan Detection detects and blocks port scan activity originating on both the LAN and WAN. IP Flood Detection detects and blocks packet floods originating on both the LAN and WAN. Checkmark Enable for each Web filter you want to set for the firewall, and then click Apply. The Web filters will activate without having to reboot the SBG941 Configuration Manager. Note: At least one Web filter or feature must be enabled for the firewall to be active. Make sure the firewall is not disabled. 8 • Firewall Pages 44
B Firewall Local Log Page This page allows you to set up how to send notification of the firewall event log in either of the following formats: • Individual e-mail alerts sent out automatically each time the firewall is under attack • Local log is stored within the modem and displayed in table form on the Local Log page Field Descriptions for the Firewall Local Log Page Field Description Contact Email Address Your email address SMTP Server Name Name of the e-mail (Simple Mail Transfer Protocol) server. The firewall page needs your email server name to send a firewall log to your email address. You can obtain the SMTP server name from your Internet service provider. E-mail Alerts Enable or disable e-mailing firewall alerts. 8 • Firewall Pages 45
B Firewall Remote Log Page This page allows you to send firewall attack reports out to a standard SysLog server so many instances can be logged over a long period of time. You can select individual attack or configuration items to send to the SysLog server so that only the items of interest will be monitored. You can log permitted connections, blocked connections, known Internet attack types, and CMRG configuration events. The SysLog server must be on the same network as the Private LAN behind the Configuration Manager (typically 192.168.0.x). To activate the SysLog monitoring feature, check all desired event types to monitor and enter the last byte of the IP address of the SysLog server. Normally, the IP address of this SysLog server would be hard-coded so that the address does not change and always agrees with the entry on this page. Field Description for the Firewall Remote Log Page Field Description Permitted Connections Check for the server to e-mail you logs of who is connecting to your network. Blocked Connections Check for the server to e-mail you logs of who is blocked from connecting to your network. Known Internet Attacks Check for the server to e-mail you logs of known Internet attacks against your network.

B Field Description SBG941. Wireless 802.11 Primary Network Page This page allows you to configure the Primary wireless network. Field Descriptions for the Wireless 802.11 Primary Network Page Field Description Primary Network When set to Enabled, beacon frames are transmitted with the Primary Network SSID. Network Name (SSID) Sets the Network Name (also known as SSID) of the Primary wireless network. This is a 1-32 ASCII character string. Closed Network With a closed network, users type the SSID into the client application instead of selecting the SSID from a list. This feature makes it slightly more difficult for the user to gain access. WPA Enables or disables Wi-Fi Protected Access encryption. WPA-PSK Enables or disables a local WPA pre-shared key passphrase. WPA2 Enables or disables Wi-Fi Protected Access 2 encryption. WPA2-PSK Enables or disables a local WPA2 pre-shared key passphrase. 10 • Wireless Pages 53
B Field Description WPA/WPA2 Encryption When using WPA or WPA2 authentication, these WPA encryption modes can be set: TKIP, AES, or TKIP + AES. AES (Advanced Encryption Standard) provides the strongest encryption, while TKIP (Temporal Key Integrity Protocol) provides strong encryption with improved compatibility. The TKIP + AES mode allows both TKIP and AES-capable clients to connect. WPA Pre-Shared Key Show Key Sets the WPA Pre-Shared Key (PSK). This is either an 8-63 ASCII character string or a 64-digit hex number. This is specified when the Network Authentication method is WPA-PSK. Show Key - When selected, the WPA Pre-Shared Key is displayed. RADIUS Server Sets the RADIUS server IP address to use for client authentication using the dotted-decimal format (xxx.xxx.xxx.xxx). RADIUS Port Sets the UDP port number of the RADIUS server. The default is 1812. RADIUS Key Sets the shared secret for the RADIUS connection. The key is a 0 to 255 character ASCII string. Group Key Rotation Interval Sets the WPA Group Rekey Interval in seconds. Set to zero to disable periodic rekeying. WPA/WPA2 Re-auth Interval The re-authentication interval is the amount of time the wireless router can wait before re-establishing authentication with the CPE. WEP Encryption WEP Encryption enables or disables Wired Equivalent Privacy encryption. Shared Key Authentication 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. 10 • Wireless Pages 54
B Field Description 802.1x Authentication This is another type of authentication and is used on top of WEP. 802.1x Authentication is a much stronger type of authentication than WEP. Network Key 1 – 4 Sets the static WEP keys when WEP encryption is enabled. • Enter five ASCII characters or 10 hexadecimal digits for a 64-bit key. • Enter 13 ASCII characters or 26 hexadecimal digits for a 128-bit key. When both WPA encryption and WEP encryption are enabled, only keys 2 and 3 are available for WEP encryption. Current Network Key Selects the encryption (transmit) key when WEP encryption is enabled. PassPhrase Sets the text to use for WEP key generation. 10 • Wireless Pages 55

Field Descriptions for the Wireless 802.11 Bridging Page Field Description Wireless Bridging Enables or disables wireless bridging. Remote Bridges Table of remote bridge MAC addresses authorized to establish a wireless bridge. Up to four remote bridges may be connected. Typically, you will also have to enter your AP’s MAC address on the remote bridge. Setting Up Your Wireless LAN You can use the SBG941 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 SBG941: • 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 SBG941 Ethernet port to perform configuration. Do not attempt to configure the SBG941 over a wireless connection. You need to configure each wireless client (station) to access the SBG941 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. 10 • Wireless Pages 63
B 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 SBG941 Required on Each Wireless Client If all of your wireless clients support Wi-Fi Protected Access (WPA), Motorola recommends configuring WPA on the SBG941 If you use a local pre-shared key (WPA-PSK) passphrase, you must configure the identical passphrase to the SBG941 on each wireless client. Home and small-office settings typically use a local passphrase. Otherwise, configure WEP on the SBG941 You must configure the identical WEP key to the SBG941 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. 10 • Wireless Pages 64
B Installing Wireless Clients Note: Use the SBG941 Installation CD-ROM to set the client security. The passcode is located on the . MAC LabelFor each wireless client computer (station), install the wireless adapter by following the instructions supplied with the adapter. Be sure to: 1. Insert the CD-ROM for the adapter in the CD-ROM drive on the client. 2. Install the device software from the CD or the modem. 3. Insert the adapter in the PCMCIA or PCI slot or connect it to the USB port. 4. Configure the adapter to obtain an IP address automatically. You may need to do the following to use a wireless client computer to access the Internet: Installing Wireless Clients If You Performed: On Each Client, You Need to Perform: Configuring WPA on the SBG941 Configuring a Wireless Client for WPA or WPA2 Configuring WEP on the SBG941 Configuring a Wireless Client for WEP Configuring the Wireless Network Name on the SBG941 Configuring a Wireless Client with the Network Name (SSID) Configuring a MAC Access Control List on the SBG941 No configuration on client required Configuring a Wireless Client for WPA If you enabled WPA and set a PSK Passphrase by configuring WPA on the SBG941, you must configure the same passphrase (key) on each wireless client. The SBG941 cannot authenticate a client if: • WPA is enabled on the SBG941, but not on the client • The client passphrase does not match the SBG941 PSK Passphrase CAUTION: Never provide the PSK Passphrase to anyone who is not authorized to use your WLAN. 10 • Wireless Pages 65
B Configuring a Wireless Client for WEP If you enabled WEP and set a key by configuring WEP on the SBG941, you must configure the same WEP key on each wireless client. The SBG941 cannot authenticate a client if: • Shared Key Authentication is enabled on the SBG941 but not on the client • The client WEP key does not match the SBG941 WEP key For all wireless adapters, you must enter the 64-bit or 128-bit WEP key generated by the SBG941. CAUTION: Never provide the WEP key to anyone who is not authorized to use your WLAN. Configuring a Wireless Client with the Network Name (SSID) After you specify the network name on the Wireless Primary Network Page, many wireless cards or adapters automatically scan for an access point, such as the SBG941 and the proper channel and data rate. If your card requires you to manually start scanning for an access point, do so following the instructions in the documentation supplied with the card. You must enter the same SSID in the wireless configuration setup for the device to communicate with the SBG941. 10 • Wireless Pages 66

If you have cable TV, check that the TV is working and the picture is clear. If you cannot receive regular TV channels, the data service will not function. Check the coaxial cable at the SBG941 and wall outlet. Hand-tighten if necessary. Check the IP address. Follow the steps for verifying the IP address for your system described in Configuring TCP/IP. Call your service provider if you need an IP address. Check that the Ethernet cable is properly connected to the SBG941 and the computer. If a device is connected via the Ethernet port, verify connectivity by checking the LINK LEDs on the rear panel. A • Troubleshooting 67
B Problem Possible Solution Wireless client(s) cannot send or receive data Perform the first four checks in “Cannot send or receive data.” Check the Security Mode setting on the Wireless Primary Network Page: • If you enabled WPA and configured a passphrase on the SBG941, be sure each affected wireless client has the identical passphrase. If this does not solve the problem, check whether the wireless client supports WPA. • If you enabled WEP and configured a key on the SBG941, be sure each affected wireless client has the identical WEP key. If this does not solve the problem, check whether the client’s wireless adapter supports the type of WEP key configured on the SBG941. • To temporarily eliminate the Security Mode as a potential issue, disable security. After resolving your problem, be sure to re-enable wireless security. • On the Wireless Access Control Page, be sure the MAC address for each affected wireless client is correctly listed. Slow wireless transmission speed with WPA enabled On the Wireless Primary Network Page, check whether the WPA Encryption type is TKIP. If all of your wireless clients support AES, change the WPA Encryption to AES.
