Teredo Connection Blocked because of Windows Firewall turned off on Work PC

Hey dude, i got the same problem.

My teredo Connection is not getting qualified. My Serverconnection is blocked. And no one from my friends can help me. Did you get an answer from the support team? I want to fix that, because i cant play forza online... it is very frustrating.

Did you know what i mean?

I hope.

it is disabled because your organisation wants it disabled, if you pc has to connect to a work domain then it must follow their measures, you want to ask you IT dept to allow it, they may then give you a reason why.

Here is a Xbox Support troubleshooting page that will walk you through NAT and Teredo Qualifying issues. It can be a lengthy walkthrough but will solve most issues. Also, NAT and Teredo usually run into problems with Antivirus programs blocking the communication
with Xbox Live services. I will usually just turn off smart firewall then click check again in the Gaming tab of Windows settings, just remember to turn smart firewall back on after reconnecting to Xbox Live services.

Hi,

There are several reasons why your network is blocked on Windows 10. It is possible that the Windows Firewall settings are blocked or your PC was unable to establish a Teredo IPsec connection to the Quality of Service (QoS) server.

To better assist you with your concern, please clarify the following information:

• Are you unable to connect to the internet on your computer?
• Are you connected wired or wireless to your router?
• Are there any error messages when you are trying to connect to the network?

1. On your PC, launch the Xbox app.
2. Select Settings > Network.
3. Under Network status, make sure Internet connection says Connected.

If you don’t have an Internet connection, you’ll have to fix that before continuing with any additional troubleshooting.

Solution 2: Make sure Windows Firewall is enabled and that the default policy is active

Windows Firewall is required to establish a Teredo IPsec connection. Even if you use additional security software and firewalls, most of these will use Windows Firewall as a base. If for some reason your Windows
Firewall has been disabled, you’ll have to enable it in order to use Xbox Live party chat and do multiplayer gaming.

To see if Windows Firewall is enabled:

1. Enter Windows Firewall in the search field on your toolbar (Cortana).
2. Select Windows Firewall from the search results.
3. On the left side of the window, select Turn Windows Firewall on or off.
4. If Turn off Windows Firewall is selected for your network type (public, private, or domain), select Turn on Windows Firewall, and then select OK.

You may need to restart your PC.

To see if the Windows Firewall default policy is enabled:

1. Right-click the Start icon, and then select Command Prompt (Admin).
2. Run the following command from the Admin command prompt:
   netsh advfirewall show currentprofile
   
   If the following output is present, the default policy is active:
