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.

    Thanks for the help!!! I think I understand the port mapping now, however based on the info you provided, it doesn't seem like I can distinguish between UDP and TCP ports, since nowhere in the port mapping tap does it talk about this. Is there a difference, and what do I do if there is?

    Also, when you say "The "host" device is the computer that will be hosting GTA ", I believe in my case this would be the PlayStation3, not my actual computer.

    Sorry for being so ignorant on this stuff!!
    Thanks again!

    Also, when setting up a static IP address, i am also asked for the Subnet Mask, Default Router, Primary DNS, and Secondary DNS. I used the values that were listed in the grey boxes in the Internet tab on my Configure Base Station window, but got an error on the PS3 when trying to establish an internet connection (DNS error 80710102).

    Do i need to set up new values for these if i am using a static IP address?

    Thanks again!!

    There is a difference, but the AirPort Admin Utility treats them the same.

    Yes, in this case your PS3 would be the host device and it would have to be assigned a static IP address.

    If you set the PS3's static IP address in the 10.0.1.x range, then the Subnet Mask = 255.255.255.0 & the Router Address = 10.0.1.1. The DNS server(s) should be the ones your ISP provides you.
