What is NAT Firewall? – The Lowdown
Getting results from your search engine is a breeze - but behind the scenes, things are a lot more complicated than that. There are all sorts of tools out there that monitor your traffic to make sure your network is secure, but one of the most important ones you may not even know about is a NAT Firewall - or Network Address Translation. You might be surprised to learn that you probably have one on your router already - its the thing that lets your router connect your private network to the internet using NAT, allowing all your devices to talk to the wider world using just one IP address. First off, let's talk about what a firewall actually is. Essentially its like a personal assistant for your computer - think of your PC as a director, and the firewall as their trusted secretary, sorting through all the incoming and outgoing mail and only letting in the stuff that the director wants to receive. When you browse the internet, stream a movie or send an email, you're sending all sorts of requests to different servers - and the firewall sits between your local network and the wider world, sorting out the incoming and outgoing data to make sure everything matches up. If it doesn't, it just gets tossed. And the good news is that the firewall protects you from all that dodgy stuff lurking on the web that could do you harm.
