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.
I just wanted to add that in some cases, the devices on your home network will have a public IP. For example, IPv6 uses a different public IP for each device on the network. You still need a router in that case, since your system still needs to know how to reach another network such as the internet.
