Configuration for Gaming

Firewall: By default, the SBG940 firewall is disabled. If you enable the
firewall, refer to the game's documentation to ensure that the necessary ports are
open for that game. If low security policy is enabled, the SBG940 can pass Xbox
™
Live by default and no user action is required. If medium or high security
policies are enabled, the firewall must be configured for Xbox Live traffic. Xbox
Live requires UDP 88:88 and UDP/TCP 3074:3074.
Port Triggering: The SBG940 has pre-defined port triggers supporting
® ® ®
DirectX 7 and DirectX 8, MSN Games by Zone.com, and Battle.net .
If your game uses one of these applications, no user action is required. For a list
of games supported by Battle Net, visit http://www.battle.net. You can also
configure custom port triggers that other games may require to operate properly.
If you set custom port triggers and enable the firewall, you must configure the
firewall to allow traffic through those ports.
Gaming DMZ: Some games and game devices require the use of random ports
or the forwarding of unsolicited traffic. We recommend configuring such a
device as the gaming DMZ host. First, reserve a private IP address for the game
device's network interface MAC address. Then designate the device as the
gaming DMZ host. You can reserve IP addresses for multiple devices, but only
®
one device at a time can be the gaming DMZ host. To use a PlayStation 2 for
®
PS 2 online gaming, assign it as the gaming DMZ host because the ports
required vary from game to game.
