Hey all. So, I'm using Mac Mini as a wi-fi router through internet sharing setting, I have a MBP with windows on it(for gaming) connected to it and everything works just fine. Until now that I need a specific port open for a windows app called Tunngle (port 11155 if that matters) and I have absolutely no idea how to do that and what requires to be done on mac and on the windows machine. Does anyone have experience in that sort of thing? Any advice on where to start?
