About service ports
Service port settings are under Optimization > Network Services: Service Ports.
Service ports are the ports used for inner connections between appliances. For QoS, you can configure multiple service ports on the server-side appliance for multiple QoS mappings. You define a new service port and then map destination ports to it, so that QoS configuration settings on the router are applied to that service port.
