Client Connector forwarding profile determines how we want to forward the traffic to the Zscaler...

When tunnels (GRE/IPSec) are already configured from trusted locations (like branch offices), the recommended setting is “Tunnel v2.0” for on-trusted networks and “None” for off-trusted. This ensures that while on a corporate network, the Zscaler Client Connector uses the pre-established tunnels, but falls back to direct or other secure methods (like VPN or ZCC tunnel) when off-trusted. This aligns with Zscaler's best practices for hybrid deployment.
