A common oversight on the F6640 is the Security > Firewall level. Even with correct Port Mapping, if the Firewall is set to "High," the ZTE kernel (likely running a BusyBox/Linux variant) will drop the packets at the ingress interface before they even reach the NAT table.
Ensure the Firewall level is set to Medium or Low, and verify that the "WAN Ping Respond" is unchecked unless you want your WAN interface to be discoverable by scanners like Shodan. Sigue esta secuencia al pie de la letra

Port Forwarding tells the receptionist: "If you get a package for Room 80 (Port 80), send it directly to the gaming console in Room 101."
