NAT Firewall is an additional layer of security for your VyprVPN connection. It blocks unrequested inbound traffic when you're connected to VyprVPN. No additional configuration or software is required. Because it runs on our servers, NAT Firewall protects any device connected to VyprVPN.
If you do not wish to use NAT Firewall, you can disable it from the Manage Services section in your account. Please note that any active VyprVPN connections will need to be disconnected and then reconnected before the change will take effect.
