Hellooooo. Please help. I am working on a computer and I need that when scanning with NMAP the TCP ports: SSH, HTTP and HTTPs of the same, these are not visible despite being open and listening. That is, something like blocking the NMAP scan.
Thanks for the reply. That is what I am needing. Restrict traffic generated by a port scanning program. This in order not to block full access to certain management TCP ports. But I do not know how to do it. Thank you.
