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.
Thats a lot of information to ask for so ill try to be very basic. A port is like a window with a guy on the other side. if you speak the same language as the guy you can have a conversation.
There are 65535 windows available. the open have guys available for conversations, the closed ones dont.
When you open a port on your computer you should have a program that “listens” at that port so that others can use it to have a conversation.
A vpn takes all of the conversations your computer wants to have and sends them to a port on a server and the program listening to that conversation sends your requests to their intended destination and then sends you the result. Its like using a middleman to have a conversation.
