It’s the one thing when I’m configuring things that makes me wince because I know it will give me the business, and I know it shouldn’t, but it does, every time. I have no real idea what I’m doing, what it is, how it works, so of course I’m blindly following instructions like a monkey at a typewriter.
Please guide me into enlightenment.
Port forwarding is related to router forwarding all the traffic it gets on specific port to your computer. Port opening is just enabling to communicate via a new port on your computer.
Both can be done irrespective of each other and sometimes they do happens simultaneously. The router could forward the traffic to a new port that you opened on your computer. But they are not synonymous with each other.
