I have my xbox 360 connected to my macbook through ethernet. On my mac i have internet connection sharing enabled from airport to ethernet. Everything works fine apart from the xbox saying I have a strict NAT.

I made sure the ports were all configured to work with my router, and UPnP is defiantly enabled on my router. I even tested to see if it was something to do with my firewalls, but even with them turned off, I still get this NAT error.

What can I do to turn the NAT from strict to open?
 
However I did encounter one problem. What router do you use and what do you use to connect to the router to give it internet (in other words, what's your router, modem, and internet company?).
 
I have a Thomson speedtouch ST585v6 router and my ISP is Aol. I don't think I use a Modem as it's a wifi connection
 
I have ruled out that it is nothing to do with the router, as I tried moving my xbox downstairs and connecting it to the router directly. No problems.
 
Do you have dialup with AOL? I'm not too aware of that router and don't know much about AOL. I'd look online but I'm on my iPhone right now.

So you're on wireless with that router, right?
 
Yes, It's a wireless router. And I'm on AOL broadband. As I said, it's not a problem with the router, rather a problem with the internet connection sharing on my macbook. iPhone ftw lol

Well.. I was trying to get you to type a command and give me the results of that but I guess that didn't work out.

Go there and follow the instructions. However, if you haven't ever tried anything like this before I'd follow it like this:

The following procedure is confirmed to work as written.

1. Start Internet Sharing if it's not already running.
2. In Terminal, type cp /etc/bootpd.plist ~/bootpd.plist
3. Stop Internet Sharing.
4. Open up TextEdit (spotlight -> type in TextEdit) and from there File -> Open -> Click on your home folder (is usually under Places on the left and has a house next to it) -> Click on bootpd.plist
5. Locate this section of the file, near the end:

<key>reply_threshold_seconds</key>
<integer>4</integer>

6. Change the value 4 to 0.
7. In Terminal, type sudo cp ~/bootpd.plist /etc
8. Start Internet Sharing.
Click to expand...

Once this is all done go to your Xbox 360 and where you edited the settings before, reset them to the default.
 
Sorry, I misread what you typed. I get this:

Also, that other setup, Iv'e tried before. I still get the same NAT error, and I think that whenever I reset my mac I have to type in all that stuff again....it's not exactly ideal.
 
Okay now when you reset the settings on your Xbox 360 and your Macbook for the internet, when you go to the Xbox 360 what IP address does has your 360 been assigned to? (It's the same place you were to go if you were to edit it)

I tried this a few weeks ago and it took me forever to get everything lined up perfectly.
 
I don't know if I should give out my IP address on here, but yes it has come up with an IP which is different....What do I do with it?
 
As long as it's like such; 10.x.x.x or 192.x.x.x, it's an internal address which points to a location on your internal network which would be useless to hackers because we cannot access your internal network.

I want to know because we need to see if your macbook is giving the 360 an IP or not.
 
I did heaps of crap to fix this, it didn't work. What did work was resetting my modem, I think. Turn it off for a minute and see if it fixes it.
 
Any more tips? Or should I just blow the £40 on a wifi adapter? Has anyone successfully got this to work without a NAT error?
