Hi people,

Have a question about VPN and NAT Firewall I was hoping you can shed light on. Is there anyone here things that NAT Firewall in addition, or having it alongside VPN and using it when desired is useful? Or is it that as I have heard NAT Firewall in a way lowers your 'security'. Overall what do you think having a VPN that also supports a NAT Firewall switch?

Why is NAT Firewall important to use with a VPN?
NAT Firewall is particularly important when you connect to the Internet through a wireless router. Wireless routers use Network Address Translation (NAT) to share an Internet connection between multiple devices on a network. When a wireless router receives an unrequested inbound scan, it doesn't know which device should receive it, so the scan is rejected. However, a VPN tunnels past your wireless router, giving you a dedicated connection to the Internet. Since your VPN connection isn't shared, unrequested inbound scans are no longer rejected. NAT Firewall protects you from these scans when you connect with a VPN.

Doesn't My Operating System Already Have a Firewall?
NAT Firewall is highly recommended for mobile devices, most of which don't have any built-in firewall protection. However, most desktop operating systems have built-in firewalls. Unfortunately, operating system firewalls aren't perfect. Connecting without NAT Firewall is fundamentally less safe because the malicious traffic actually reaches your device, leaving your system's firewall as the only line of defense. Hackers and bots look for bugs in your operating system and mistakes in your OS firewall permissions. NAT Firewall blocks this traffic completely, thus eliminating a range of exploits. While we do recommend you continue to use your OS firewall, we highly recommend NAT Firewall as an additional layer of security.
