To use port mapping, you must configure TCP/IP manually on the computer that is 
running the web, AppleShare, or FTP server.
You can also set up a computer as a default host to establish a permanent IP 
address for the computer and provide inbound port mapping information to the 
AirPort Extreme Base Station or AirPort Express. This is sometimes known as a DMZ 
and is useful when playing some network games or video conferencing.
To set up a default host:
1
Open AirPort Utility, select your wireless device, and then choose Base Station > 
Manual Setup, or double-click the device icon to open its configuration in a separate 
window. Enter the password if necessary.
2
Click the Internet button, and then click NAT.
3
Select the “Enable Default Host at” checkbox. The default IP address is 10.0.1.253.
4
Enter the same IP address on the host computer.
Logging
You can set up your wireless device to log status information to the Mac OS X system 
log or the Syslog application on a Windows computer. This is helpful for understanding 
problems and monitoring a device’s performance.
To set up logging:
1
Open AirPort Utility, select your wireless device, and then choose Base Station > 
Manual Setup, or double-click the device icon to open its configuration in a separate 
window. Enter the password if necessary.
2
Click the Advanced button, and then click Statistics.
