Strict NAT and Teredo Tunneling errors on a university network

I did contact the IT folks at my university. I was told that it is a hardware compatibility issue stemming from my Xbox One console. There is nothing they can do on the network side of things. They said several students have had this issue now over the past
year, that they (the IT department) have been in contact with Microsoft engineers, and it was ultimately resolved by sending the consoles back to be replaced by units with a different hardware and/or firmware configuration. I've been trying to follow up on
this but it always seems to just confound the tech support from Microsoft.

Thanks for the reply.

We always suggest that the console owner restore to factory default. This has helped in some instances but usually not.

I look forward to hearing back from you. Thanks for your help.

Hey there, Tim!

The Xbox One functions quite well with a public IP address, as we often suggest setting up the console under DMZ or directly connect to their modem; both of which will give the console a public IP address, as I am sure you are aware.

It seems the problem you may be running into is the Teredo IP address issue, and that is likely what is at fault for all the issues (as long as each device is getting its
own public IP address). Sometimes, the Teredo error will show up and

restoring the console to factory defaults is required. While we don't know the cause for this, if the factory reset doesn't happen, the error is a result of the ISP themselves.

Our
Network Connection Troubleshooter is quite in depth, and may be able to help you troubleshoot users that call you guys. Have you given it a shot yet? They should be able to work with you, this troubleshooter, and your access to their routing device to help
nail down any possible networking issues. I suggest trying it out, especially with any Teredo IP errors you guys may receive a call about.

My main suggestion is to try that out first. What I am going to do on my end is pass this along to the appropriate people and see what I can dig up for you. I will post back once I have more information from them.

There is no NAT on our system. It is the same issue that is referred to by GIJoeBob in the opening of this thread. I understand what you are getting at but there is no NAT to adjust. I have already been through all of this with several people when I tried
using the regular troubleshooting channels. As I already stated, I have talked to our IT department. In a bit more detail, they said it appears to have something to do with what the xbox console does the very first time it is set up. Why replacing the console
worked for other people, I don't know. But according to them it does.

@FancyDevotee340 hey hey

The only resolution is contacting IT department, only them can reconfigure they network hardware.
