RV345 - Incoming ports showing closed instead of stealth

Hello,

 

I have a RV345 small business router.  I use the Shields Up service from GRC.com to test my router against incoming ports.  This service scans ports 0 thru 1055.  Under normal circumstances, all ports should show stealth as I do not do any kind of remote management with the router, it is all done on-prem in my home office.

 

The scan shows these ports are marked as closed:  80, 443, 465, and 993.  When I originally setup the router, these ports were marked stealth along with the rest of them.  I am not sure what change I made to have these ports marked as closed.  I would rather these ports be configured as stealth so if my IP gets scanned the attacker won't receive a response.

 

Where should I begin?  My firmware is the latest which is 1.0.03.22.

Regards.
