This example shows how to set up a basic transparent web proxy. You can use the transparent web proxy to apply web authentication to HTTP traffic accepted by a firewall policy.
In previous versions of FortiOS, web authentication required using explicit web proxy. Now, FortiOS also supports a transparent web proxy. With transparent web proxy, you can forward your user’s web traffic to the proxy without requiring your users to reconfigure their browsers or publish a proxy auto-configuration (PAC) file.
