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
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.
