Nighthawk M1 Mobile Router Can't Get to Devices Publically

[xzibit]

I have a Nighthawk M1 Mobile Router running on ATT locally here in the US, anyone know if it's possible to get connectivity to a device behind this router? I have a need to setup a server that I can SSH into and no matter what I do I can't seem to get through with basic ICMP and or SSH.

Tried setting up for ip pass-through and device can get an the public IP (10.x) but no luck with either ICMP and or SSH to the device. If I connect a laptop locally and allow both it and the server to get a local IP out of the network pool 192.x.x.x ICMP/SSH works fine. I've also tried just doing typical port forwarding for SSH (22tcp) and or ICMP(7tcp/udp) no luck.

I'm suspecting that ATT isn't giving a true public and doing some sort of firewalling on their side, I typically get a 10.x.x.x IP (example 10.122.106.40)

A 10.x address is a local IP subnet, not public-facing. Others are 172.x and 192.x. In this case, 'local' may be internal to AT&T, not local to your home network. I also see a 10.x IP as the IP of my M1. I assume AT&T is NAT'ing things and the actual public-facing IP is different. When I go to https://www.whatismypublicip.com/ to check my public-facing IP it is 107.77.x.x. Even with that public-facing IP you may not be able to establish a connecting back into your M1 from an external source due to the complexities of that NAT'ing. Others with more background may be able to offer ideas on how to make that work.
