People just kept coming back.
4:30
Yeah, people kept asking me if I was going to do it again, and I was surprised because I thought for sure, you know, now that things were starting to open up around that time, that, you know, there's many other choices.
4:44
And so, no, they really liked it.
4:46
They liked the fact that they can sit in the shade.
4:49
That's a free thing, and I don't know what to tell you.
4:53

Okay, so in that handling the IP translation, how do we ensure that the right data reaches the right device within a network? Or to put it differently, what directs external traffic to specific devices inside a network?
2:31
Port forwarding works in a reverse way to network address translation.
2:37
So let's assume that this PC here, you want to turn it into a web server.
2:44
So people from the outside, customers from the outside of your local area network will access your PC web server.
2:52
Let's say that it's an online store.
2:54
Now, all of these devices are using the same public IP address.
2:59
So how would the traffic be routed specifically to this PC and not to the camera or to the laptop, which is not a web server, or to your IPTV? So this is where port forwarding comes into play.
5:34
Could you give us a real-world example, maybe comparing a few of these devices in action so that we can see how they work together in a typical network?
