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.
To add to your analogy if i may, the firewall is kind of like a security guard or doorman at the building entrance. All mail has to go through him first and if something is addressed to a closed flat (port) he simply doesnt let it get delivered.
Yep! The security guard is also given a bunch of rules to follow such as “don’t let anyone outside of our neighbourhood contact door 22”, which will also determine whether messages get delivered or not
