I'm trying to scan a network using Nmap, but I’ve noticed something strange:
- When I ping a server, I get a response, indicating it's online.
- However, when I run an Nmap normal scan, the host appears to be unreachable.
Could this be due to firewall rules, ICMP filtering, or something else? What steps can I take to troubleshoot why ping works but Nmap scan doesn’t?
