"You'll need to point your external DNS to an available IP and configure your firewall to NAT that to your SW server on port 443 (or the secure port you are using). Then you can access Spiceworks remotely by navigating to:
https://IPADDRESS:PORT You don't need to include the port number if you are using port 443. top "
Find the port you used when installing SpiceWorks and go on your firewall, open the external port number you have towards the ip of the SpiceWorks box.
That's it !
Then from outside your network, you can type
http://YOUR_EXTERNAL_IP:PORTNUMBERCheers,
