I don't mind helping, making suggestions but the path and setup you selected could be plain broken.
If I were to do this my phone would have it's hotspot enabled and that for me is how it works over and over and over (game over? no.)
Good luck on finding someone to follow you into what I know is a tar pit area. I will only suggest a change but net enter the pit.
I am searching for someone who is knowledgeable in the networking area to help me. So i have my phone tethered to my laptop and from there i enabled network sharing. i tried connecting my xbox One to it, but am getting errors left and right. They include "UPnP not successful"
"your network is behind an address/port symmetric NAT"
Im guessing it has something to do with the IP address details and stuff. please contact me if you are willing to go waist-deep with me into this and try to help me
