Windows: set the firewall for OPC UA server applications

When an application that includes an OPC UA server is run in Windows, the port specified in the Endpoint URL Server property of the object must be opened. In this case, a window opens in Windows that requests the configuration of a firewall rule, unless there are rules set in advance.

Note

the rule is created with the name qruntime.
