How do I check if ports are blocked or not

Hi All,

I'm not a network eng. so please be patient.

We have a 2x virtual UTM 9s recently upgraded to the latest firmware (9.711-5.1) and wanted to know if there is a way to check or manage ports through the web portal. So basically where we can check if ports are open/closed, etc.

We're trying to check if a specific port used by an application has been automatically allowed after the upgrade. 

Any other info please let me know.

Thanks
