How can I fixed teredo issue and also port 3544 not being open?

Hello

So I did manage to do all this and when I go to my xbox I have a good sign of NAT (moderate) but it says upnp not successful I found everything you told to do but I need to do something extra I guess

NAT, Teredo and Port problems are depending on what network hardware you use. So please, if you could tell us which internet provider you use (and if it's a cellphone based 3G/4G/5G or cable or DSL provider), and which hardware is used to go online (e.g.
Broadboand Modem and WiFi Router) we can help you better.

Please provide the make and model of your hardware as detailed as possible. For example don't tell us "I have a Netgear". Instead, tell us something like "I have a 'SpeedyFast SB123' DSL modem from Best Internet, and a Netgear XY7411 WiFi router."

For help with Teredo errors let's follow the testing multiplayer troubleshooter and select that specific error message.

Post back and let us know if you still run into issues once those steps are done.

Hi there thanks for coming back to me so quickly.

So I have a

Fritz box fon WLAN 7360 V2

INTERNATIONAL EDITION.

I think its a router and modem My Internet provider is XS for all.

If that changes anything my flat mate has a ps4 in his room and it's working for him but maybe that interfere

Let me know if you need more details.

I don't know if it's in the international version of the Fritz Box as well, but my German Fritz Box has a Teredo Filter enabled by default.

I try to translate the menu names to English to the best of my knowledge, but the actual menu names might be named somewhat differently. I hope you'll still find the correct settings.

You need to go to the settings of the FritzBox and enable the "Advanced View" (I don't know if that's the proper translation. But you can reach the setting by clicking on the "three dot menu" in the upper right, and turning the switch on for something that
in German is labeled "Erweiterte Ansicht").

After turning on the "Advanced View", go to "Internet" then "Filter" then there should be a Tab called "Lists". Scroll down and remove the Checkmark for the Teredo Filter.

Then under "Home Network" in the "Network" sub-menu go to the "Network settings" Tab. Further down the page should be two options to place a checkmark to allow apps to have access, and transmission of status messages via UPnP.

Enable both.

Restart your PC to let it detect the UPnP enabled device.

And hopefully that should now work.
