See how to set up the Network Scan OpenVAS port range
The Pentest-Tools.com Port scanners let you select common ports, a specific port range, or a list. See here the default port list.
In order to fix a “no open ports” scan result, you should rescan with Nmap’s option “Don’t ping host (-Pn)” enabled or OpenVAS “Check if host is alive before scanning” option disabled.
