Floating  • Network Concurrent

A hyper-efficient business trend.


Network Licensing

Network licenses (also known as floating licenses) allow multiple users to share a limited pool of licenses in a local network. 

After installing the GstarCAD License Server on the computer being used as a server, the server will handle requests for licenses from users' computers. 

If you have a team of 20 people and 10 licenses for a product, the entire team will share access to the 10 licenses, while no more than 10 people can use the software at the same time.



While Stand-alone licenses use a license file installed and activated for each computer, and can be used only in that machine, network licenses are installed and activated only one time on your server.

 When a license request arrives, the server determines whether the proper license for a requested product is available. If an appropriate license is present and not in use, the server will allow access to the software. 

helps ensure that your users have access to the right software at the right time and enables you to control the use of your software licenses easily and efficiently

  • Network licenses are sharable by users from across the company.
  • Easier to administer since it simplifies software asset management and IT tasks.
  • Cost-effective since you don’t need to order as many licenses.

As the licenses are stored on a server, you cannot use the software if you are not connected to the network. Although the server software does not require a powerful system, it is mandatory that the computer hosting the license server be running and available while there are computers using the licensed software.

VPN (Virtual Private Network) allows users to connect to the workplace network via an internet connection. This simulates a physical connection to the network.

This is the most secure and seamless end-user experience, as the client machine uses a VPN profile or some authentication to connect directly to your GstarCAD Network License server over the internet, through a Virtual Private Network.

* Enable and configure VPN server at your existing internet route or any server which VPN services.



That is the easiest and simplest way to share GstarCAD network licenses across the internet. Once the port of license server is open through port forwarding (default server port number is 27000-27009), client machines can access the server across the internet and acquire a license.

On this setup, you as an end-user only need to enter the IP address or the domain name of the GstarCAD network license Server on the address field when activated.

In this setup, the GstarCAD network license server is publicly exposed on the internet. Anyone who knows the IP/domain name of the server along with the port is running can acquire a license.

If you need to restrict the access, you may use the “License Option (OPT file)” feature on the License server for finer control on who is allowed to obtain a license.

* You need to configure the port forwarding at the internet router or firewall.
