In many of our blogs, we discuss the importance of hiding or masking your computers IP Address by using a VPN service. In conjunction with those blog posts, we wanted to offer a solution that readers can utilize before a VPN fails. When a VPN fails, it usually means that your computer can not connect to the Internet through the VPN. If that happens, other programs that utilize the Internet, but connect through your Internet Service Provider (ISP) may still access the internet leaving your system exposed. To help prevent the accidental exposure of your IP Address we recommend utilizing some unique properties associated with your firewall.
Cut the Ties:
Using your firewall, you can create unique rules that eliminate the Internet connection of any program that does not access the Internet through the VPN service. In short, without a VPN connection then your computer is not connected to the Internet, and your computersIP Address can not be accidentally exposed.
Creating unique rules for your firewall to follow:
A firewall is like those mechanical arms that are installed in parking garages or parking lots. The cars approach enter a code and the arm swings up allowing the car to enter or exit. That is the gist of what a firewall does on a basic level. It blocks information access and exiting information until a security clearance has been achieved. In the case of a VPN failure, your firewall can help save your personal information and keep your network secure. The key is setting up these special rules before the VPN fails.
The goal is to route all internet traffic through the VPN so that if the VPN fails the internet connection is lost. These changes to TCP/IP do not mean that you can not manually access the Internet, they simply mean that any program that is used to accessing the Internet can no longer do so without the VPN being active. The reason this works is that it prompts the computer operator to connect manually to the Internet. This means that if you are not at your computer and the VPN fails, nothing can escape, and no intruders may enter. Your computers IP Address is safe. Your computer network is safe. The data that you store on your computer is safe.
Under normal circumstances, a VPN such as hidemyass.com is the perfect way to hide your IP Address, but it never hurts to prepared for those “what if” situations that can happen at any moment.
