What is this?

This is a batch script that resolves many Teredo-related connectivity issues for multiplayer Xbox games on Windows and helps you address potential problems that may arise.

How do i run the fix?

• Disable any VPN software, also if you have an antivirus, disable the firewall protection in your antivirus.
• On this github page, on the top right, press the green button "Code" and than "Download zip" to download the fix script. Unzip the folder, open teredoFix.bat, windows defender will show up, click on More informations and then Run (code is open-source so you can check that it is safe), when it asks Do you want to allow this app to make changes to your device? select yes.
• The new version of the script automatically checks the teredo status and helps you figure out what to do by giving you instruction, select option 1 to enable teredo and follow the suggestions of the script, enjoy :)

Still not working, i think i need to port-forward on my router, how do i do it?

• Some router will block teredo so you may need to do this thing called port-forwarding, so let's start!
• Search cmd on windows bar > open cmd > write ipconfig and hit enter > look for Predefined Gateway and Ipv4 address, save them for later (ex. 192.168.1.1 , 192.168.1.45)
• Open web browser and paste the Predefined Gateway ip (ex. 192.168.1.1 or 192.168.0.1 etc...) on the top search bar and hit enter
• Access your wifi router using username and password (they usually are on the bottom of the wifi router), (the password is not the same that you use to connect to your wifi).
• Once you logged in search for Port mapping and than create a new rule, some routers have the option port mapping for known applications, that's the preferred option.
• If you have port mapping for known applications than select it and select xbox live for windows application, than select your PC as local host, (if it asks for the ip address paste the Ipv4 you saved previously)
• If you don't have port mapping for known applications than create your own custom rule:
  ◽ Under Traffic comming from:
  You set up your interface (If you can choose between interfaces choose the one that has your public ip address in it (ussualy set by default), if you don't know your public ip address search on google "what's my ip").
  If it asks: Any host = set yes
  If it ask: Any port = set no, than specify port 3074
  ◽ Under Traffic directed to:
  Host name = select your computer if there is a list of all conected devices
  Host ip = paste Ipv4 you saved previously (It's the local ip address of your computer)
  Port = Same port, 3074
  
• APPLY ALL MODIFICATIONS
• Wait 5 minutes (Sometimes router will take some time to apply modifications), then check teredo using teredoFix.bat
• If it still does not work try rebooting your wifi router, wait 5 minutes and check again
• Waiting and rebooting can sometimes do magic things with port-forwarding, it seems that some routers apply the new rules just when they feel like it.
