I use Zenmap on Windows 11 to detect open ports on Metasploitable2. The problem is that zenmap is not able to detect active hosts ( it does detect that there is a host, but it seems to be down to Zenmap). But, when run the Zenmap scan on the same target from Linux 6.0.0-kali3-amd64 then I am able to successfully run a scan and see the active ports.

Here is my command on Zenmap with profile set to Intense scan:
nmap -T4 -A -v 172.16.xxx.xx
The output of the Zenmap scan is as follows:​

Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn​

Solution
You can test with nmap scanme.nmap.org If it isn't returning anything open you may also have something locally blocking the scan or a security device (firewall etc) blocking on your network side

As noted in the output 1 IP address (0 hosts up) try -Pn. nmap will try to ping and will fail if ICMP is being blocked. Adding -Pn will skip the ping test and check for open ports.

As suggested, I ran a nmap scan on the target with -Pn, but it didn't work. Here I have attached the result of the scan.

Host discovery disabled (-Pn). All addresses will be marked 'up' and scan times may be slower.

Then you may need to validate the firewall is allowing traffic. There isn't any special config needed for nmap to work.

I tried nmap on the site you mentioned and it worked. Also, when I nmap my target machine (metasploitable 2) using Kali Linux it works. My Kali is also hosted on the same VirtualBox.
