What is required for Tunnel with Local Proxy configuration?

The requirement for Tunnel with Local Proxy configuration involves a Forwarding Profile PAC targeting the local listener. In this setup, a PAC (Proxy Auto-Configuration) file is crucial as it dictates how web traffic is directed through the local proxy and the Zscaler service. The PAC file contains rules that determine whether traffic should be sent directly to the Zscaler cloud or processed by the local listener first. This approach allows for granular control over how applications connect to the internet, optimizing the performance and security of the data traffic.

In contrast to the other options, a standard browser configuration alone doesn't ensure that all traffic is effectively routed through the local listener, nor does it set specific rules for traffic handling. A full system reset and reconfiguration is unnecessary and overly complicated for implementing local proxy tunneling; such steps would usually be reserved for situations where foundational configurations are fundamentally flawed. Similarly, requiring a VPN connection first does not align with the functionality of the Tunnel with Local Proxy, as the local proxy serves to manage connections independently of a VPN, focusing instead on streamlined and secure traffic management to the Zscaler platform.
