What Is A NAT Firewall?

The Network Address Translation (NAT) firewall on a router protects private networks. It functions by allowing internet traffic to pass only when a device on the private network expressly requests it. A NAT firewall protects a network’s identity by preventing internal IP addresses exposed to the internet.

What Does NAT Firewall Do For You?

When users surf the web, exchange emails, or view movies online, they send information requests to specific websites—the firewall functions as a barrier between the user’s local network and the rest of the internet. The firewall compares the information provided to the information you requested; everything that matches is let through, while anything it doesn’t is denied. Consequently, the firewall protects users from unwanted hazardous internet traffic that may otherwise harm their computers.

NAT Firewall And OysterVPN

On a device, OysterVPN encrypts internet traffic and sends it through an intermediary server in the user’s selected area. OysterVPN employs NAT firewalls. Instead of the user’s wi-Fi network filtering out unwanted traffic, the OysterVPN server does so. OysterVPN, which uses a NAT firewall, assigns each user a unique private IP address. Thus, all of the benefits of a NAT firewall on a wireless router are extended to your VPN connection. In addition, OysterVPN users get access to a NAT Firewall, protecting them from hackers who may gain access to their system via links left open by their apps. OysterVPN supports all main operating systems. Therefore, users can rest certain that their whole network is secure.
