Auto close/deny port after time
Leaving RDP open is huge security risk, so I prefer it to set "deny" by default and only open before using RDP. Most likely I do have to remember to close RDP port after doing my work, but it would be nice if there is a timespan that will close the port after it was opened. So if I forgot, I wouldn't leave RDP port open, it would automatically close after given timeout.
This is really good feedback. We will look into this.

I know that this isn’t a perfect solution, but my workaround to this was to create a windows 10 vm (jumpbox) with auto shutdown enabled and restrict all my other vms to only allow from the jumpbox. This means the longest the rdp port will be open is 24hrs.
