Shields Up by steve gibson found the following openings in BitDefender 2019.What to do to fix these holes?
I always turn off stealth mode or portscan traffic protection. Because my fritzbox cablemodem is blocking portscans anyway plus hardware firewall. Stealth mode for what. If somebody wants to hack you, he does it anyway.
Costs only performance.

PS forget this shields up and try this link from heise.de to test your router for leak holes.

you can even scan every single port of u do. I tested port 80, its secure.
Heise showed me, that the ports 80, 443 are secured. Green.
We germans know a lot bout computation. *Honor* ;=)
