It also depends on the service provider, example(Comcast doesnt support any sort of UPnP on their XfinityWifi hotspots, and they block all VPN traffic.) Which means, that you cant even join a game on link, if connected to a hotspot, but Xbox Live, and PSN will both work. lol. This also applies to a lot of 4g internet providers. So, if it doesnt work after setting it up on your end, I would get a hold of your service provider, and they might be able to point you in the right direction.
