4g network connection?

hello all, i have master server,proxy server, and facilitator up and running, now when i have non-wifi connection i can start a server with proxy but cannot be connected to as client, or if wifi starts server as host, 4g can poll host list but cannot connect as client, this is a 2 player game, any advice is greatly appreciated
