I just bought and setup a RV110W. I noticed while scanning it from the WAN side that it always has port 443 open, even when remote management and VPN access are disabled. Why is this port still open, and how do I close it? Or is this a bug in the firmware? I am using firmware version 18.104.22.168, which is the most up-to-date for this unit. Having open ports allowing unsolicited contact from the WAN side, especially inadvertant ones, is a major security hole.
I should be able to lock this down with no open ports on the WAN side. Any idea why this unit is doing this? Should I return this device, or is this fixable?
