Default Configuration in ZTunnel 2.0
Default to DTLS with the ability to fall back to TLS as necessary.
System Proxy Settings Migration Recommendation
Enforce a no-proxy configuration when using tunnel mode.
Automatically Detect Settings Proxy Action
The client sends a WPAD (Web Proxy Auto-Discovery) lookup to find a proxy.
Use Automatic Configuration Script Proxy Action
Configures the Zscaler Client Connector to set a custom system PAC file to download and run,
explicitly proxying traffic.
Use Proxy Server for Your LAN Proxy Action
A hard-coded proxy import with the ability to bypass local addresses.
GPO Update Purpose in Proxy Settings
To provide a GPO update/force from Active Directory to set the proxy settings on the machine.
Understanding GPO Updates Importance
To avoid conflicts between forcing proxy settings and using WPAD scripts.
Forwarding PAC Significance
1|Page
,With tunnel mode configuration, avoid setting any forwarding PAC file to natively intercept
traffic and tunnel it to the Zero Trust Exchange.
Application Profile Function in Zscaler
Maps forwarding profiles to different users and devices based on specific criteria.
App Profile PAC URL Role
Defines the Zero Trust Exchange node to be used based on the client's geographic IP
information.
Custom PAC URL Configuration Item
In an application profile.
Custom PAC URL
References the PAC file configured in the ZIA Admin Portal to make decisions on traffic
forwarding or bypassing.
Override WPAD
Prevents the system GPO WPAD configuration and ensures the forwarding profile's WPAD
configuration is used.
Restart WinHTTP
Ensures the system refreshes proxy configuration once Zscaler Client Connector is established,
specific to Windows devices.
Zscaler SSL Certificate
If not pushing own certificates, enabling this option uses the certificate provided by Zscaler for
SSL inspection.
Tunnel Internal Client Connector Traffic
Health updates and policy traffic pass through Zscaler tunnels towards the Zero Trust Exchange.
Cache System Proxy
Stores the system proxy state from before installation and reverts to previous settings if the
connector is uninstalled or disabled.
Supportability in Zscaler Client Connector
2|Page
,Ensures business continuity in case of issues with updates, allowing for reverting to previous
versions if necessary.
Zscaler root CA
The Zscaler root CA as well as custom root CAs can be deployed within an organization.
SSL certificates in app profile
Ensuring that the SSL certificate is installed.
Bypassed applications in Z-Tunnel 2.0
Microsoft Teams or Zoom traffic.
Default address range in Z-Tunnel 2.0
The default 0.0.0.0/0 address range and all ports 1 to 65,535 TCP and UDP.
Zscaler as DNS resolver
Zscaler acts as a DNS resolver.
Handling DNS requests from DHCP
The client may query that directly, and Zscaler will see the traffic once it comes through and
make a DNS re-resolution request.
Forwarding Profile PAC files
Steering traffic toward or away from the Client Connector.
App Profile PAC files
They steer traffic towards or away from the Zscaler Cloud after the Client Connector receives it.
Forwarding Profile PAC purpose
It states which HTTP proxy is going to be used for a specific URL.
Application Profile PAC routing
It routes traffic after interception and determines the geographically closest Zscaler
Enforcement Node (ZEN).
PAC files on ZIA Admin Portal
They take a URL and a host as input and return an answer of sending the traffic 'DIRECT' or
'PROXY'.

, Migrating existing PAC files to Zscaler
By using Tunnel with Local Proxy and configuring the browser to treat Zscaler Client Connector
as a proxy.
Browser behavior in PAC to tunnel mode
The browser will lose the definition of what constitutes an intranet site, potentially prompting
user authentication for intranet sites.
Defining intranet sites in tunnel mode
By explicitly defining them within the intranet zone and using configurations like the
AuthServerAllowList.
Key characteristic of ZTunnel 2.0
It can include or exclude traffic at the adapter level and pass it into the Z-Tunnel 2.0.
Z-Tunnel 1.0 interception
Traffic at the network layer on ports 80 or 443.
Tunnel with Local Proxy configuration requirement
A Forwarding Profile PAC to target traffic directly to the local listener on Zscaler Client
Connector.
Traffic routing in route-based mode
Through a routed adapter configured on the machine, following the routing table.
Application PAC role in route-based mode
It processes the traffic and routes it either to the Zscaler cloud or directly to the internet.
Tunnel 2.0 configuration exclusion
The RFC 1918 address space.
Handling DNS requests by Zscaler
They are tunneled to the Zscaler cloud for DNS resolution.
Forwarding Profile PAC control
The system PAC file and the HTTP proxy to be used for a URL.
Result of using Forwarding Profile PAC for local proxy
