Wireless Cable Modem Gateway SBG900
Configuration for Gaming
Firewall:
By default, the SBG900
Firewall
is disabled. If you enable the
SBG900 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 SBG900 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 SBG900 has pre-defined port triggers supporting:
DirectX
®
7 and DirectX
®
8 MSN Games by Zone.com Ba ttle.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

for
PS
®
2
on-line
gaming, assign it as the
Gaming DMZ
because the ports required vary from
game to game.
