networking 4g connection?

hello all, i have my first multiplayer game set up using unity3d networking, it is a 2 player game, i have my own master server,proxy server and facilitator set up and running, everything works fine going through wi-fi, but when i am using 4g connection i am having problems connecting to host, if host is wifi 4g cannot connect, if host is 4g wifi cannot connect but it can poll host lists, i have tried Network.useProxy = true; on client and server side, i just need to be a little more informed about this i guess, im determined to figure this out, thank you for your time
