If you have been looking for a complete guide on what is a NAT firewall, then this article is exactly what you have been looking for! Technical subjects tend to get confusing when someone from a non-technical background tries to get an in-depth understanding of a certain topic. We will explain what is NAT, how to edit NAT firewall settings, and last but not least, what is the purpose of NAT, and what does NAT means.
What is a NAT?
NAT, also known as Network Address Translation, is the process in which your IP information is modified into IP packets, that are then transferred to the required site. These IP packets are bundles of your information that are transferred via the internet. NAT is most commonly used in typical WI-FI routers for a number of devices that connect from one WI-FI connection to access the internet using one external IP. Since these IP packets (simply speaking bundles of personal information) are vulnerable and could be accessed by harmful third parties, the NAT process acts as a so-called firewall, blocking any non sanctioned incoming traffic.
Network Address Translation firewalls are extremely important when it comes to your cybersecurity. If you are thinking of stepping up your cybersecurity, your best choice would be to use a VPN (Virtual Private Network) that has a built-in NAT Firewall. Your VPN will encrypt all of your IP packets, making it close to impossible for any third parties to get your location or any private data that could potentially be located in those packets. Also using VPN helps to protect the user’s personal data, so using the Internet will be absolutely secure.
Why do I need a NAT Firewall?
Now you must be wondering if a NAT Firewall is a so-called data guardian, why do I need a VPN with a built-in NAT Firewall? Simple. When a Nat firewall stands alone, it’s simply not enough to protect your data from any serious third party dangers. Firewalls are technically fairly simple tool that is not 100% reliable when it comes to ensuring your data security. For the maximum security of your data, it is highly recommended that you use a VPN that has an in house Nat Firewall. Such firewalls are usually way more sophisticated than basic NAT and have more functions to protect your data.
