Gaming Configuration Guidelines
The following subsections provide information about configuring the SBG1000 firewall and DMZ for gaming.

Configuring the Firewall for Gaming

By default, the SBG1000 firewall is disabled. If, as recommended, you enable the firewall, refer to the game’s
documentation to ensure that the necessary ports are open for use by that game.
The pre-defined SBG firewall pol icies affect X-Box LiveTM as follows:

Configuring Port Triggers

Because the SBG has pre-defined port triggers for games using any of the following applications, no user action is
required to enable them:
•DirectX® 7 and Direct X® 8
•MSN Games by Zone.com
•Battle.net®
For a list of games supported by Battle.net, visit http://www.battle.net.
You may need to create custom port triggers to enable other games to operate properly. If you set custom port
triggers and enable the firewall, you must customize the firewall to allow traffic through those ports. To create
custom port triggers, use the Gateway > PORT TRIGGERS — custom Page.

Configuring a Gaming DMZ Host

Some games and game devices require one of:
•The use of random ports
•The forwarding of unsolicited traffic
For example, to connect a PlayStation® 2 for PS2® on-line gaming, designate it as the gaming DMZ host becau se
the ports required vary from game to game. For these games, we recommend configuring the gaming computer or
device as a gaming DMZ device.
To configure a gaming DMZ device, on the Gateway > LAN — dhcp leases Page:
1Reserve a private IP address for the computer or game device MAC address.
2Designate 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.
Low XBox Live data can pass through the firewall. No user action is required.
Medium or high To enable X-Box Live traffic to pass, you must configure:
•Choose Custom on the Firewall > POLICY — basic Page
•UDP 88:88 and UDP/TCP 3074:3074 on the Firewall > POLICY — advanced Pag e
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.
