ZCC Working while on Trusted Network

Hi All,

Greetings!!!

Can someone within the community folks help me to understand ZCC ( Z-App) working while a user is on Trusted network. Assuming I already set the trusted network criteria in forwarding profile;

  1. Does Zpp goes to fail open mode when it detects trusted network ? Considering the fact I have transparent forwarding from the network edge device using GRE/IPSEC tunnels to public service edge?

  2. Or does it still establishes its own tunnel 1.0/2.0 depending on the configuration in the profiles ? In this case will it be a tunnel 1.0/2.0 inside a GRE /IPSEC tunnel at the edge device? or how does it work in this way?

  3. What would be a particular use case to use a Zpp for ZIA service when user is in corporate network and all my internet based traffic can be routed to public service edges using transparent forwarding at edge routers ? even my browser will use this GRE/IPSEC tunnel to forward interned based traffic to Zscaler public edges?

@Mac1809 When the app detects “trusted Network” based on the criteria you have configured in forwarding profile, you can go with one of the following options:

Tunnel: Even though you are on a trusted network, all your port 80 and 443 traffic will still be tunneled through Zscaler client connector (ZApp) using it own Z tunnel with an HTTP connect header.

Tunnel with Local Proxy: Though you are connected to a trusted network, Zscaler client connector will install a pac file on your device so that all traffic is tunneled to Zscaler through local host.

Enforce Proxy: Traffic will not be tunneled, instead system proxy settings will be used. You can also push proxy settings via ZCC while using “enforce proxy” option.

None: On detection of trusted network, Zscaler client connector “turns off” and does nothing. “On trusted network” message is displayed. All traffic is sent direct.

Hope this information helps you out!

Thanks Raj for your comment!!!

And one more thing if you can help me …what is the exact difference between these two action (Enforce & Apply on network changes) for Configure System proxy setting option in forwarding profile .

The given explanation is as follows

Enforce: Client Connector enforces your proxy settings by monitoring for network changes and reapplying setting

Apply on Network Changes: Client Connector only enforces your proxy settings when the network changes, it does not monitor for proxy change afterward;
