    Connection to Teredo behind CGNAT not possible - Xbox-Network


    Hello together,

    I recently downloaded Forza Horizon 4 again and tried to play with a friend of mine. While I downloaded the Game from a different location as my home and played from there, I was behind a public IP on my side.

    However, my friends ISP is using CGNAT which is causing him to not have an own public IPv4 address which might be required for Teredo. As IPv4 is running out and CGNAT is more and more common, is there a solution on how to play online with friends behind CGNAT?

    Can you for example use the Toredo Network with nativ IPv6 only?

    I can't belive this is a thing that Microsoft didn't thought of and I am currently confused if I am just to "smart" to think of the solution. Can anyone help me on how to play online behind CGNAT?

    Checking his Toredo state via CMD:

    • Typ : natawareclient
    • Servername : win1910.ipv6.microsoft.com.
    • Clientaktual.-intervall : 20 Sekunden
    • Clientport : unspecified
    • Status : offline
    • Fehler : primäre Teredo-Server nicht über UDP erreichbar
    Code:
    (In case someone is asking for the Server-verification: I am using Toredo successfully on the same server)Thank you very much in advance for any help!Best regards,
    
    :)

    Teredo is unable to qualify

    If you can’t hear your friends online, or you can’t join or host an Xbox Live multiplayer game, go to
    Network > Settings in the Xbox app and check
    NAT type
    .

    If it says Teredo is unable to qualify, your PC is unable to obtain a Teredo IP address.

    Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity between devices behind routers that use network address translation
    (NAT).

    Failure to obtain a Teredo IP address can occur when there’s an issue with your Teredo adapter, when a device on your network is blocking the Teredo protocol, or if there’s software installed on your PC
    that’s disabling Teredo functionality. Without a Teredo IP address, you’ll be unable to use party chat or do multiplayer gaming on Xbox Live.

    Cannot Connect to Online Services while In-Game

    If you can’t join or host an Xbox Live multiplayer game, or you can’t connect to a party chat session, press the
    Start button, select Settings > Gaming >
    Xbox Networking and check NAT type.

    If it says Teredo is unable to qualify, your PC is unable to obtain a Teredo IP address.

    Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity between devices behind routers that use network address translation

    Teredo is unable to qualify

    Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity between devices behind routers that use network address translation
    (NAT).

    Failure to obtain a Teredo IP address can occur when there’s an issue with your Teredo adapter, when a device on your network is blocking the Teredo protocol. Without a Teredo IP address, you’ll be
    unable to use party chat or do multiplayer gaming on Xbox Live.

    Check to see if Teredo connectivity is blocked when a VPN client is connected, or while a VPN network adapter is installed

    Some VPN clients will disable Teredo connectivity while the VPN client is connected, and some VPN clients that install a network adapter that will disable Teredo until the VPN adapter is removed. If you’ve
    installed a VPN client and Teredo is still disabled even while the VPN client is disconnected, check to see if you have a network adapter named
    TAP-Windows Adapter V9 installed:

    1. Right-click the Start icon, and then select Device Manager.
    2. Select View > Show Hidden Devices.
    3. Select Network Adapters.
    4. Identify any adapters that have a name like TAP-Windows Adapter V9. Right-click the adapter name, and then select
      Uninstall.
      Note While uninstalling the VPN network adapter should unblock Teredo connectivity, this will also likely cause issues with the VPN client software. If you still require VPN functionality along with Teredo support, refer to the support documentation
      for the VPN client.

    Xbox One won't connect to multiplayer

    Hello EPICONLP,

    Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity
    between devices behind routers that use network address translation (NAT).

    Sometimes, you just need to go into your router to activate teredo, or "Teredo tunneling". If it is already activated, turning that setting off and then back on can help.

    Don't forget to try the troubleshooting in that support article given to you by Amber above. Click on that link, and select the teredo error to begin troubleshooting.

    Hope this helps!
