Do network discovery and security audits in Airshell (nmap)
Map your network for discovery or security audits with the Airshell command
            nmap.
Run nmap from the overlay side of an
                Airwall Gateway.  This
            reference includes examples for the most common and useful options. This command is
            based on the publicly-available  Nmap Reference guide, where you can find
            additional examples.
You can optionally specify which overlay port group
            to scan. For example, nmap ovl1 -n -sP 192.168.3.1-10 or nmap 1
                -n -sP 192.168.3.1-10. If you do not specify an overlay port group
            (for example, nmap -n -sP 192.168.3.1-10 ), the scan is run from the
            first overlay port
            group. 
For nmap options, enter nmap --help.
For more options and examples, see the Nmap Reference guide (external link).
