If your computer uses a firewall, you must configure ports to support  SolidNetWork  Licensing. 
In the firewall software, you must add two SolidNetWork License  ports (for example, SNL-in-port and SNL-out-port) to the firewall exceptions list. For details about configuring these ports, consult with  your system administrator. 
If you are using  Windows Firewall on a supported Windows operating system, you must modify ports on the SolidNetWork license manager computer and modify the SolidNetWork license file to distribute licenses to the license client computers.
