Changing Network ports on Android

Hello,

I have been using virtual here to connect my android and PC. The PC is the client, while the android is the server. Whenever the phone is on wifi it connects with the PC client great, but whenever I try it with cellular it does not work. I have been trying to figure out solutions and I think that changing my network ports might do the trick.

So I was wondering, how do I change the network ports on my Android phone virtual server and my PC virtual client?
