Setting Up NAT Port Forwarding
Thomas recently received an Xbox 360 as his birthday gift. His friends invited him
to play online games with them on Xbox LIVE. In order to communicate and play
with other gamers on Xbox LIVE, Thomas needs to configure the port settings on
his ZyXEL Device.
Xbox 360 requires the following ports to be available in order to operate Xbox
LIVE correctly:
TCP: 53, 80, 3074
UDP: 53, 88, 3074
Thomas may set up the port settings in two ways. He can either set the Xbox
360’s IP address as the default server (see
Section 4.5.1 on page 58
), or he can
configure the port settings for Xbox 360 (see
Section 4.5.2 on page 59
).
4.5.1
Default Server
It is much easier to set the Xbox 360’s IP address as the default server if it is not
already assigned to another server. There is no need to enter any port number.
Note: Setting a device as the default server exposes the device to potential attacks.
Any port service trying to access the ZyXEL Device’s WAN IP address will be
forwarded to the default server. It is recommended that you set up a firewall rule
to protect the device.
