Where can I find NAT?

wompai
Ey guys,

I've been trying to connect an XBOX 360 to XBOX Live using a network bridge that has been setup on a spare computer. The bridge is working fine but when I test my network connection I get a message about my NAT settings being set to moderate, with these settings I cannot use some XBOX Live features. I have searched my FR!TZBox's user interface for these options, but I have not yet found them. Does anybody know where I can find them? Or a way to fix the problem another way.

Thanks in advance

NOTE: The network bridge is already up and running perfectly. The spare computer has the following hardware and software installed:
AMD Sempron 2600+ (1.6 GHz)
256 MB DDR RAM
GeForce 5200fx 128 mb
Maxtor 10GB
54 Mbps wireless controller
Ethernet controller (directly plugged into XBOX)
WinXP SP3

    And what are it's security settings?

    Security settings have not been touched so, they are still set to the standard values.

    What does that even mean? You get the message from the XBox or where?

    Fritzbox, oh boy. Look in the documentation. Maybe post a link to the docs for your exact model and revision so we can look.

    NAT

    akm_fll

    Network Address Translation. You won't find this term in your computer manual. It is a feature of firewalls. The important detail is that you seem to understand that your computer is acting as a bridge -- a bridge that joins two networks. The first network lives off your ethernet port and has two members: your computer and your XBOX 360. The second network lives off your wireless controller and has two members that you care about: your computer and XBOX Live. I believe the Windows command you want is ipconfig. That will show you that the ethernet port has one address and the wireless controller has a different address. Your XBOX communicates through your computer to reach XBOX Live. Your computer translates addresses to make this happen. What your computer apparently will not do is translate from XBOX Live to your XBOX 360. You need somebody who understands networks to help you from here. They have to know what ports XBOX Live uses, what ports XBOX 360 uses, and how the translation between those two settings has to be done. If you go to Wikipedia and search for "Network Address Translation", you will get a good (although somewhat technical) explanation of NAT.

    I didn't think of it until I was going to sleep, but that wireless controller is communicating with a wireless router in order to reach XBOX Live. That wireless router will also have the ability to do Network Address Translation (NAT).

    In short, on your very simple network, there are three places where Network Address Translation could be an issue:
    1. on the firewall settings for the ethernet port. (Not likely, but possible)
    2. on the firewall settings for the wireless controller port. (somewhat possible)
    3. on the wireless router that you did not mention, but which is certainly there (most likely)

    There is also one other strong possibility. You don't have a problem with Network Address Translation at all. The ports you need might just be blocked by the firewalls at the three places listed above. That is probably the most likely scenario.

    This is not a hard problem to fix, but you need somebody who understands networks and firewalls. It is also easier if they have access to your computer.

    I just set my firewall settings to off. The XBOX still reports a problem with my NAT settings, but playing games like COD MW2 works perfectly. I also heard something about port forwarding, I have not yet done this because I did not yet notice any severe problems.

    You are NOT fixed! Turning off firewall ports on an Windows box is an EXTREMELY ill advised thing to do. What you did was mask a symptom. The post below by wompai lists ports that XBOX Live needs. Turn your firewalls back on. Try enabling the ports wompai mentions on your firewall. For a variety of reasons, I don't think port forwarding would help you, but I could be wrong.

    My apologies. I should have said, "posted by tech_ed" rather than "posted by wompai". I am sorry. (See the next reply)

    XBOX live needs the following ports:
    88 - UDP
    3074 - UDP
    3074 - TCP
    You may need to send (forward) these ports to your xbox from your router NAT configuration screen, look for "Port Forwarding".

    I guess it wasn't the firewall then, but I can just play games on my XBOX without any problems. And, btw, the spare computer I'm talking about isn't used for anything else than enabling internet for the XBOX. It's dedicated to that particular task and doesn't do anything else. So I guess that turning the firewall off would not be so dangerous... (The firewall is only turned off in Windows not in the router)

    WRONG! Wrong! Wrong! There are volumes of security exploits built around just the scenario you describe. You would be very vulnerable.
    There are two firewalls on the Windows box that you need to adjust. One is the firewall on the wireless controller port and the other is the firewall on the ethernet port. On both firewalls, you want to open the following ports:
    TCP 80
    UDP 88
    UDP 3074
    TCP 3074
    UDP 53
    TCP 53
