Strict NAT - ATT Uverse NVG589 Modem issues

So I have tried everything from turning off all the Firewall settings, turning off Packet Filter, using NAT/Gaming Hosted Applications to open ports, IP Passthrough, and a few other things but cannot get my NAT to go to OPEN. I had a technician out here
today checking all the lines, and everything comes back fine. I switched from DSL to not only upgrade my internet (3mb/s to 12mb/s) but to try and fix this problem. I've talked to customer support for hours at ATT and have gotten nowhere.

Could someone please help me with this?

:)

 

Connection/NAT issues with ATT NVG589 Uverse Modem/Router

Hey there Juiced,

Sorry to hear you're having issues connecting using your new router.

I would definitely recommend reading through the suggestions in our
How to Open NAT sticky thread. It has some great steps for port forwarding and further solutions if you're still having NAT issues.

Please let us know how those all work for you and we'll go from there.

 

Connection/NAT issues with ATT NVG589 Uverse Modem/Router

this is what I have configured under NAT/Gaming on my router

it doesn't work and I can't figure out whats wrong.

 

Is your Xbox One connected directly to the NVG589 or do you have a router connected to the NVG589 then to the Xbox?

 

Having the exact same problem with comcast except when I run a multiplayer test it says no teredo ip, I have done EVERYTHING in my power to fix it and it still is strict and it still says no teredo ip. I have even bypassed my router completely and plugged
it straight into the modem, STILL CAN'T GET A TEREDO IP. WHAT

 

Sammity Sam Sam, check this link:
forums.xbox.com/.../1769913.aspx

Follow my instructions there for the Teredo IP error, that will fix that. Also, Master reset wont fix Teredo IP because your router is set to enable Teredo upon a master reset, so you have to disable it manually after wards

 

My console always changed from open to strict my way of curing it which is a pain.is to reboot router but make sure xbox is off load up,reboot router load up reboot router load up boom open again and works fine.

Make sure upnp is ticked inside your router aswell

 

The NVG589 does not support UPnP which causes Nat issues especially if there are multiple xboxs connected to it.

Do you have more than one Xbox connected to it?

Also, do you have your own router connected to the 589? If so you would be causing a double Nat.

And FYI, I have the 589. I have no Nat issues because I use my own router, properly set up, behind the 589. Here is a tutorial for the set up. www.dslreports.com/faq/17734
