Additional Network Ports for Multiplayer Gaming: Secondary teredo server unreachable over UDP. ...

Hi GetOuttaMyTree,

I tried the first two links you sent me in the past. No luck there.

I've been researching and I found that my modem does not have Teredo blocker or something like that.

I also portforwarded all of the XBOX ports and my Teredo stats changed to Network: managed (it does not say "qualified") , but after a really short while it got back into the same error "the primary teredo server unreachable over UDP".

I bought this game last year and I really really and I mean REALLY want to play it online.

Thanks for trying to help!

Is there seriously no fix to this problem? Its not like other companies can not create multiplayer capabilities on windows...only MS seems to struggle with their own software.

In my case the only difference is, that the client port is "unspecified"

Can you check to make sure you don't have one of those port forwarded ports in "port filtering"? That blocks the port and could cause this.

I would also try toggling ipV6 in your network adapter settings and if you've done all on that help page I would then refer you to update your router's firmware or reset your router to default settings. I would then ask the ISP if there's anything they can
help with.

To use the services and have an open NAT it's necessary to enable the ports via portforwarding on the router. In addition Teredo offers a tunnel between the IPV6 protocol on IPV4 on a static port.
So besides the ports:
88 (UDP)
3074 (UDP and TCP)
53 (UDP and TCP)
80 (TCP)
500 (UDP)
3544 (UDP)
UDP 4500 (UDP)
TeredoPort: range between 49152 and 65535 (select only one port for Teredo) or 60209 as the default port

You'll then need to use the port selected for Teredo and configure it: netsh interface Teredo set state client clientport=[TeredoPort / 60209 (default)].

This is good knowledge. Setting the ports fixed the problem. I still am not able to see the teredo tunnel adapter thing in the device manager, but Xbox networking seems good to go. Thank you for the information, you're a time saver !

Hi there Ogeff,

Thanks for reaching out here in Xbox Forums. I understand there is an issue with the Teredo on the network configuration. To help clarify:

• What type of connection are you using?
• Have you reviewed the network configuration in regards to the Xbox Live Ports?
  • Port 88 (UDP)
  • Port 3074 (UDP and TCP)
  • Port 53 (UDP and TCP)
  • Port 80 (TCP)
  • Port 500 (UDP)
  • Port 3544 (UDP)
  • Port 4500 (UDP)

Some game developers require you to open additional ports. You should always check the game developer's website to see if the game you're playing needs additional ports to work.
