We run SolidWorks in a lab environment with SolidWorks SolidNetWork License Manager version running on Windows Server 2012 R2. Any time the licensing server changes state (server rebooted, service restarted, etc...) the port that clients connect to the server seems to change. The default port 25734 stays the same but I have seen clients attempt to connect to the server on ports between 49200 and 49999. Is there a documented range for this that I can open on my firewall or a way to set this port staticly so I do not have to reconfigure my firewall each time. The license server is on a protected VLAN and policy is to limit the number of ports opened to it as much as possible.
