Motorola SURFBOARD SBG1000 - Manual (Page 12)

12 Wireless Cable Modem Gateway SBG1000
Configuration for Gaming
Firewall: By default, the SBG1000 Firewall is disabled. If you enable the
SBG1000 firewall, see the game manufacturer's documentation to ensure the
necessary ports are open for use by that game. If low security policy is enabled,
the SBG1000 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
X-Box Live traffic. XBox Live requires UDP 88:88 and UDP/TCP 3074:3074.
Port Triggering: The SBG1000 has pre-defined port triggers supporting:
DirectX
®
7 and DirectX
®
8 MSN Games by Zone.com 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 a Gaming DMZ device. First reserve a private IP address for that
device's network interface MAC address and then designate it as a DMZ device.
You can reserve IP addresses for multiple devices, but only one device at a time
can be the Gaming DMZ. To connect a PlayStation ® 2 for PS ® 2 on-line gaming,
assign it as the Gaming DMZ because the ports required vary from game
to game.
