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.
