USB800 IP Passthrough?

Is there a way to configure the USB800 for IP Passthrough?  Even in IPPT mode, the device connected to the USB800 gets a private 10. number.   When connected to a router, I am having trouble with double NAT.  Is there a mode where the USB800 passes the public IP address to the device it is connected to?

my thoughts

Some, like the Nighthawk, seem to have the ability to engage a request for a public IP instead of CGNAT.  I do not think that's a feature of your device.

That's strange. I always get a 192.168.1.x address.

I believe you are speaking of the private IP issued to clients of the USB800.  I am speaking of the IP assigned to the USB800's WAN interface.

Wait....

What are the next octet or two of the WAN IP address:

10.x is ALWAYS a private IP, so I'm guessing you're looking at something that isn't the WAN IP?

And to the above post, the USB800 is most definitely NOT a hotspot. It's a 4G USB modem dongle.

Conceptually, the USB800 works pretty much like a hotspot for one computer, but using a USB port instead of Wi-Fi.  Ignore the fact that it looks like a Network Adapter, and treat it like a Gateway/Router/Modem (or Hotspot).

It has a WAN interface and a LAN interface.  LAN interface talks to your computer.  WAN interface talks to "The Internet Side."  So you see a WAN interface of 10.x.x.x ?

Yes, on the WAN side is the 10. Number.  It appears AT&T is using CGNAT assigning the 10. Number and the router is seeing that number as the WAN address so there’s double NATing going on.  Does AT&T offer an option of a fixed PUBLIC IP address for devices like this?

Only AT&T will know for sure, but I'd guess not, as these are generally designed for road warriors and businesspeople.

Are you running the latest firmware/software on the modem?

I have never heard of the USB800 having access to the public IP reservation pool.  I have heard of some true hotspots having such access.
