I have been trying to make a small game server for months now and I can't get anything to work. I have properly port forwarded the right ports for the game on my router and allowed them through the firewall on my computer. I have even tried using a different router so I am really starting to wonder if it has something to do with MTS. I have heard stories of people having to contact their ISP and get them to do something but everytime I try to ask customer service about it, they say they can't help me.

Sorry to be the bearer of bad news,

The statefull firewall infrastructure, that most/all wireless carriers employ, won't let connections not initiated by the user through for security purposes. In this case all the firewall would see was a random connection trying to connect to your phone/stick and with no prior history of a connection there it would not be allowed.

This is employed for the user's security so their handset isn't attacked constantly by the wider internet. Because the of this, and the fact that phone gets a different IP every time as well as network address translation (NAT), there isn't a way to enable a game sever (or any server) in the wireless network.
