This article will provide you with the necessary steps to help secure your web browsing through a SOCKS 5 Proxy Tunnel at RPI. By using this Tunnel, you will be able to use RPI's remote access servers to access the internet. This is especially useful if you are remoting in from outside the United States that has restrictions on certain websites needed for RPI work.
