i usually get a nat problem on xbox live, It usually say's I have a "strict nat", this stops me from finding online games. A way to make it open you need to resart your router.

To all people that have nat type problems. I used to get nat type strict udp blocked when i bought this game. I searched on internet forums about the solution and you need to open two ports (8889, 3478) on your router settings ( its called port forwarding). After that, at the PLAY button scrren, my nat type was again strict. When i launched the game i played for a while and then i closed it. The next time when i started the game, on the PLAY button screen the nat type was open!!! and now i dont have any problems! I hope i have helped you with my story.

Here are some steps to improve your connection to the TDU2 servers:

First please make sure your profile has been created as Online.

Test Drive Unlimited 2 uses the TCP/UDP port 8889 to communicate with servers and others players.

Solution1: Turn on UPnP on your network hardware

Universal Plug and Play (UPnP) is a standard that helps routers communicate effectively. If your router or gateway supports UPnP, make sure this setting is turned on.
Please refer to your hardware documentation for help turning on UPnP. Most hardware manufacturers have Web sites that include support information.
If you change the UPnP setting on your network hardware, restart your hardware and test your network connection by re-launching the UpLauncher.

If you receive a NAT Open:UPnPUsed message, your network is ready for playing TDU2.
If you still receive a NAT warning (orange or red), please try the next solution.

Solution2: Open network ports

Your network hardware or firewall might be blocking communication with the Xbox LIVE servers.
If you're connected to a network through your workplace or a college, ask the network administrator to open the following port:
TCP/UDP 8889 (TDU2 game port)
TCP/UDP 3478 (UpLauncher STUN tests port)

Part1:To get your computer’s IP settings

On your computer, click Start, type cmd, and then press ENTER. Note If you’re using Windows XP, click Start, click Run, type cmd, and then press ENTER.
At the prompt, type ipconfig, and then press ENTER.
Find your network connection (for example, look for something called "Local Area Connection" or "Wireless Network Connection"). Write down the numbers for the following items:
IPv4 address (or IP address)
Subnet mask
Default gateway


Now let’s set your PC’s IP settings.

Part2: Open ports on your router or gateway

Now let’s open ports on your router or gateway, so that your network hardware can communicate with the TDU2 servers (this is also called "port forwarding").
Open the TCP/UDP port 8889 with the IP address found in the previous step.
Please, refer to the router manufacturer for help with opening network ports.
