Receiving on multiple (udp) Ports

I’m using an XBee WiFi Module in API Mode over UART and I’m wondering if it’s possible to receive data on multiple ports. I’m wondering because the Module is capable of sending on multiple ports and the “RX (Receive) Packet: IPv4” Frame that’s generated by the Module when data is received actually contains an “Destination Port” field, but it only receives data on the Port that I’ve configured earlier using the C0 Command. So what’s the Idea behind that field if it only reports back data that I already know?

Thank you for your help.
