: HELP PLEASE...!!! double nat issues

Connextsd to ATT gateway 192.168.

Connected to Orbi 10.0

Xbox waa configured with a manual IP both times within the range.

Hardwired the Xbox directly to the ATT "gateway" and it still shows strict NAT. I got the ports forwarded through my Orbi's setup and my xbox shows "Open nat" until i perform a nat test and it goes straight back to strict/double NAT. I have tried to go
through the ATT's gaming/nat setup and forwarded the same ports as well with the same result. After resetting the Xbox it goes to open but if i perform any tests especially nat test... right back to strict/double. This happens both wireless and wired to
either the Orbi, or the ATT paperweight =-(

To clarify a little on the gateway side as well... As far as i can tell its is bridged but then this ATT has so many settings inside of it who knows. I have shut down the ATT box's wifi bands totally and did the " IP Passthrough" in order to use my Orbi
system as the primary routing setup for the house.

Sounds like a good plan.

Keep us up-to-date and we'll go from there.

On another note: Do you know for sure if your ISP is leasing you a public IP address?

If you take the Ethernet cable from the WAN interface of your AT&T device and plug it directly into your PC/Mac, you should (hopefully) get a public IP address. This address is routable out on the Internet. So, hopefully, you should see an address other
than an address from the private range (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)

Great!

192.168.x.x is an address from the private range, meaning, your AT&T device is still performing Network Address Translation (NAT) for its connected devices.

What is the model number of your AT&T device?

Do you know for sure that, as a customer, you have the option to bridge this device? Some providers have a custome made UI that, sometimes, offers a limitation on what customers are able to configure. Bridge mode is sometimes such a configurable feature
that may only be available from the ISPs end to configure.
