Setting Up a VPN on Your Router: Pros, Cons, and How-To Guide

In the quest for comprehensive online privacy and security, many users are turning to the option of installing a VPN directly on their router. This approach offers unique benefits but also comes with its own set of challenges. This article explores the pros and cons of router-based VPNs and provides a step-by-step guide on how to set one up.

Understanding Router-Based VPNs

A router-based VPN creates a secure, encrypted connection for all devices on your home network. Instead of installing VPN software on each device, the VPN runs directly on the router, extending protection to every connected device automatically.
