After C-Werk is installed, you can change the port range for Servers, the gRPC API port number (see Ports used by the C-Werk Software Package).
To change the gRPC API port number, create an NGP_NATIVE_BL_PORT system variable, and set its value to the required port number (see Appendix 9. Creating system variable).
To change the port range for a Server, use the Network settings utility (see Network settings utility).
