Home Internet Port Forwarding working in 2021?

Hey - read through these posts, ngrok was my first thought.

I’m just getting started on this - I only started on T-Mobile 2 weeks ago and the issue is just as described.

I can possibly containerize the software I write if it solves the issue, if I can, I will release to opensource and provide a link, but it seems straight forward. Dependencies would be basic for linux and android users - I am on the dev community for Win11 where I'll work with others for a Win10/11 thread to begin working on a conversion if need be - ngrok works on both operation systems, my only unknowns as of now is Google/Apple - but I have dev accounts there as well and can begin the threads appropriately but wouldn't be able to personally advise on the issue of app creation unless I really dedicate the time.

I'll keep this as the main thread until I finish development or run into a major issue, for the release of any application I will begin a new thread with the application download / docs / issues page and provide a link to this thread here . That will keep this organized. If issues occur from there, appropriate arrangements will be instructed on how to contact me on the repos where I make it available and reach out to the developer community at TM about forking the repo to theirs as well. 

Give me some time - my schedule is pretty tight but tonight I will more then likely have mine correctly configured - from there I'll plan the build appropriately and build a repo where you can follow the progress I make - as I make it and ask question or leave comments. I don't expect an initial release for Linux distros / Android 10/11/12 - to be longer the 1-2wks max for a stable version. Others will need to be patient as I work with other developers on the issue on other operating systems, I doubt they would be much more complex, but I need to develop it in c++ or another basic OOL to abstract it to API's that can then work with delivery systems that are, as well, cross platform compatible. Java will be the answer there as I know AirBnB and Moz have java engine extensions to other C like networking languages for Apple and Gentoo distro's like Google's Chrome OS.

Please be patient - I in know way am associated with T-Mobile, just a customer. I love to solve problems - this seems like a good place to start anyway. If I hit bottlenecks or anything that will disrupt the development process, I will update here so no one keeps there hopes up too long.

All my best - KS
