In this recipe, you’ll learn how to create a basic transparent web proxy setup. You can use the transparent proxy to apply web authentication to HTTP traffic accepted by a firewall policy.
In previous versions of FortiOS, web authentication required using the Explicit Proxy. Now in addition to the Explicit Web Proxy, FortiOS now supports a Transparent Web Proxy. With the transparent web proxy, you can forward your user’s web traffic to the proxy without requiring your users to reconfigure their browsers or without needing to publish a proxy auto-configuration (PAC) file.
Note: This is just a basic setup, and authentication will be covered in a future recipe.
