Opening Ports on Airport Express for GTA IV

Question

I am told that to play Grand Theft Auto 4 (GTA 4) properly, I need to "open ports" on my router and enable UPnP (Universal Plug-n-Play).
The ports I am supposed to open are:
UDP
3478
3479
6672
28900
TCP
80
443
5223
3478
3479
3480
8001
8080
27900
On my Windows 2000 machine, using the AirPort Admin Utility, when I configure the AirPort, I get a window that has a "port mapping" tab.
Is this how I open the ports listed above? If so, it asks for a private IP address, Public Port, and Private port. How do all these relate to the port numbers above?
In the configure base station window, i can't find any mention of how to enable UPnP
Thanks!!!!!
PS, don't hate on me for having a PC, i'm just waiting until Apple comes out with a BluRay capable laptop...

Hello Psychos40. Welcome to the Apple Discussions!
On my Windows 2000 machine, using the AirPort Admin Utility, when I configure the AirPort, I get a window that has a "port mapping" tab.
Is this how I open the ports listed above? If so, it asks for a private IP address, Public Port, and Private port. How do all these relate to the port numbers above?
Yes.
To setup Port Mapping:
Assign a manual IP to the host device
The "host" device is the computer that will be hosting GTA and needs to be accessed from the Internet. Under Windows 2000, you would use Network Settings to assign a static IP address to this computer. Note: Be sure to assign an IP address outside of the DHCP range provided by the AirPort Express Base Station (AX) default range of 10.0.1.2 - 10.0.1.200, like 10.0.1.201
To setup port mapping on an AirPort Express Base Station (AX), connect to the AX's wireless network, and then use the AirPort Admin Utility to change these settings:
Port Mapping tab
o Click "Add"
o Public Port: <enter the Port # which will be accessed from the Internet>
o Private Address: <enter the static IP address from above>
o Private Port: <either enter the same value as the Public port or the value you want your application/service to answer on>
o Click "Ok"
o Repeat the last series of steps for each port you wish to map.
In the configure base station window, i can't find any mention of how to enable UPnP
Unfortunately, that's because the AirPorts do not support UPnP. Instead, the AirPorts have a similar feature known as "NAT Port Mapping Protocol." You enable/disable this function on the Ethernet Port Security tab under Base Station Option within the AirPort Admin Utility. Note: Although NPmP is similar, it is not the same as UPnP and may not offer the same features. If GTA requires UPnP, the AirPort's NPmP feature may not support it.
