If you are using Windows Firewall, you must modify firewall port settings on the SolidNetWork license manager computer.

1. In Windows, open the Control Panel and then double-click Security Center.
2. Click Windows Firewall.
3. On the Exceptions tab, click Add Port.
4. Type a Name (for example, SNL-in-port) and a Port Number (for example, 25734) and then click OK.
5. For the second port, click Add Port on the Exceptions tab again, specify the other port’s name and number (for example, SNL-out-port and 25735), and then click OK. Note the port number, as you will reference it later when modifying the SolidNetWork license file.
   If you use Workgroup PDM, you must modify Workgroup PDM port numbers in Windows Firewall. Typically, these ports are 20000 (VaultAdmin), 30000 (Data), 40000 (Request), and 80 (Viewer).
6. Close Windows Security Center and Control Panel.
