Hey I somewhat know about tech and stuff but right now I am I struggling with a seemingly unfixable problem. I want to be able to join party chat and join a game and have a good connection to my friends to play Black Ops 3 on my Xbox one. The only source of internet in our dorms run through a single modem and have a single Ethernet connecter in my dorm. I have tried calling the IT here and asking him to open ports that deal with skype because I didn't think he would help at all if I told him I needed help gaming. I have learned that I need to have access to ports such as UDP: 3075 and TCP: 3075. I am open to spending any sort of money to either buy a router but I did that last semester and the same NAT setting came up and I still couldn't talk to my friends. I am willing to do whatever it takes and hope someone can help. I heard VPN could help or something.
