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.

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.

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.

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.

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

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.

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.

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.

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
