I was working on a PC recently and ran a quick firewall test using Shields Up. Oddly enough, most of the ports came back as closed and maybe a half dozen were identified as Stealth. Usually when I run this test on someone's PC most if not all of the ports show Stealth. Are there any security concerns or pitfalls of this type of configuration? Did not have time to start figuring out what they had installed, they are not tech savvy at all and could not tell me what was installed, is it possible there is no firewall and they are relying on just a software firewall? They are have a PC connected via Ethernet and a mesh wireless system installed for portable devices. Something is handing out IP addresses although I have never seen a home network hand out IP addresses starting with 10.x.x.x which this one is doing.
