About automatic configuration

A proxy auto-config (PAC) file defines how web browsers and other user agents can choose the appropriate proxy server (access method) automatically for fetching a given URL.

The Smoothwall Filter supports built-in PAC scripts and custom PAC script templates. A built-in script is an auto configuration script that you can customize with additional settings such as exceptions. A custom script provides advanced functionality where you can use a script customized to suit your organization.

You can define the policy for each interface, by configuring the proxy address that the configuration script should direct clients to.
