NAT (Forwarding) in T-Mobile Gateway
I recently signed up for T-Mobile internet, and I am VERY disappointed that I could not even forward NAT traffic to my home security system. I saw that this was discussed 7 months ago in a previous...

T-Mobile (business, in my case; don't think it matters) can't do port forwarding. But my ssh tunnel(s) worked, at least for a little bit. I use autossh, which re-establishes connections when they fail (due to routing changes, etc). It has been very reliable for me in the past to get around bad/broken NAT situations.
But I found that my ssh tunnels would only last for a short time (Arkadyan modem, using a router on the LAN connection). Then I read from another post somewhere else on this forum that t-mobile simply closes TCP connections without traffic after a period of time (looks like maybe as short as 5m).
So I changed the ssh settings on my server to add a keep-alive, and all is working perfectly. I have three ports forwarded on my LAN through an ssh connection to a server in the cloud; you could probably use ngrok for this (free accounts I think). I have a camera, ssh to a server, and another port forward to an IoT device, and all three have been working perfectly without interruption for over a week. I get between 120 and 250Mbps down and 30up pretty consistently.
I’m sold, and am currently on hold cancelling my AT&T DSL account!
Could you run thru a quick setup?? I'm jus tryna to game on my pc and Tmobile internet is blocking some of my games from connecting. I'm using Persistent SSH which is and alternative to autossh.
It would be much appreciated.
