NAT (Forwarding) in T-Mobile Gateway

For my part, I live on a boat, using the Inseego Wifi Router.  Bandwidth is good, but I have the problem when trying connect to Minecraft hosted instances and playing astroneer.  I also have an Android Samsung A52, that I use as a hotspot on the T-Mobile Network.  Zoom works for meetings w/ work (kind of had to set up my laptop as a DMZ machine to get it to work).  Long story short.  I have an iPhone that has Verizon, and no problems.  On the Verizon network I have no problem with Minecraft, Zoom, or Astroneer.  Whatever T-Mobile is doing on their network to hack around their lack of IP addresses (or whatever their major malfunction is) does not appear to exist on Verizon.  I tried ZeroTier and was not able to get it to work, but I'm sure I probably could if I had the time/motivation to get a VPN properly working.  The main problem is that the IP address that presents to the Internet can never route back to my actual box, e.g. you connect to the outside world but the  IP address presented to the Internet  will never route back to your local box because of the way CGNAT (carrier grade NAT) that is being implemented on T-Mobile.  In other words, you make a connection to a remote host and they try to connect back to the IP address that they think you are connecting from and it doesn't actually connect back to the host that you are connecting from.  It's not a problem w/ the modem or your device, it's on the T-Mobile network.  It works on Verizon, not on T-Mobile.  If you want to solve this problem either T-Mobile has to fix their broken network, or you need to switch to Verizon.
