Z-Tunnel 2.0 extends forwarding beyond web proxy traffic by securing all IP unicast traffic through DTLS/TLS tunnels to the Zero Trust Exchange. This enables Cloud Firewall and other controls to inspect all TCP and UDP ports, and ICMP where supported, rather than only browser HTTP/HTTPS flows. Option C (All TCP and UDP ports as well as ICMP traffic) is correct because Tunnel 2.0 is the all-ports-and-protocols forwarding model for Client Connector.

Why the other options are incorrect:

A. TCP ports 80, 443 and 8080 only: Ports 80, 443, and 8080 describe common web proxy traffic. Tunnel 2.0 forwards broader IP traffic, including TCP, UDP, and ICMP.

B. Any HTTP/HTTPS traffic as well as DNS: DNS resolves names to IP addresses; it is a support service, not an access protocol or scoring engine by itself.

D. All Web ports as well as FTP and SSH: RDP, SSH, and VNC are privileged remote access protocols for desktop, shell, and graphical administration.
