dbFront is a web application. This means that your clients should be able to access dbFront by simply browsing to your server. No additional installation or licensing is required.
1) http://localhost/dbFront
While running locally on your server you can use the URL http://localhost/dbFront, but this URL only works when you are running directly on the hosting server.
2) http://%YourServerName%/dbFront
Your local network clients would connect by browsing to your server using the URL http://**%YourServerName%**/dbFront, where the value %YourServerName% would be replaced with the name of the hosting server or workstation.
This of course assumes that there is a network connection between your server and your clients.
