How to Set Up a Proxy Server on Windows/Mac/Linux

“When the wind does not blow your way, adjust your sails.” This ancient Egyptian wisdom speaks to the timeless necessity of adaptability, a principle that applies as much to navigating the Nile as it does to securing your digital footprint in today’s interconnected world. Just as sailors once relied on the stars and the wind, modern users rely on proxy servers to chart a safe course through the turbulent waters of the internet. Here, we will guide you through the practical steps of setting up a proxy server across the major operating systems: Windows, Mac, and Linux.
