What is fport used for when rx and tx Devices

Hi, I am still learning about Lorawan and I have successfully installed and received some data from a device into my own LoraServer. I see in the received data a property fPort. What is this property and what is it used for? When sending a downlink message to the device do I need to use the same fPort value that was on the uplink message? Thanks for any help. Gary
