Adding Windows Firewall Exceptions for SOLIDWORKS Network-Based Products

The purpose of this article is to show the procedure for adding Windows Firewall exceptions. SOLIDWORKS SolidNetwork License Manger, SOLIDWORKS PDM, SOLIDWORKS Manage, SOLIDWORKS Electrical, SOLIDWORKS Visualize Boost, SOLIDWORKS Simulation Worker Agent and other SOLIDWORKS network-based products need open communication between the client and server. To achieve this open communication, Windows Firewall rules need to be added to open up the lanes for network communication.

Default Ports

Below is a list of default ports used by SOLIDWORKS products, that you will need to add in the later steps of this guide depending on which product you are looking to add the exception for.
