ÂTo provide specific IP addresses to specific computers on your wireless network, click the Add (+) button below the DHCP Reservations list, and follow the onscreen instructions to name the reservation and reserve the address by MAC address or DHCP client ID. If you choose MAC address, click Continue and enter the MAC address and specific IP address.

Next you can set NAT options for the network. Click NAT.

ÂYou can set up a default host on your network. A default host (sometimes known as a DMZ) is a computer on your network that is exposed to the Internet and receives all inbound traffic. A default host may be useful if you use a computer on your AirPort network to play network games, or want to route all Internet traffic through a single computer.

ÂYou can set up NAT Port Mapping Protocol (NAT-PMP). NAT-PMP is an Internet Engineering Task Force Internet Draft, an alternative to the more common Universal Plug and Play (UPnP) protocol implemented in many network address translation (NAT) routers. NAT-PMP allows a computer in a private network (behind a NAT router) to automatically configure the router to allow parties outside the private network to contact this computer.

Included in the protocol is a method for retrieving the public IP address of a NAT gateway, allowing a client to make this public IP address and port number known to peers that may wish to communicate with it. This protocol is implemented in current Apple products, including Mac OS X 10.4 Tiger and later, AirPort Extreme, AirPort Express, and Time Capsule networking products, and Bonjour for Windows.
