Default Port Numbers
The following is a list of 32 and 64 bit components with the default ports they listen on:

Component Name | Default Port
32 bit Enterprise Server Service (Windows) | 6500
64 bit Enterprise Server Service (Windows) | 6502
License Server (Windows, Unix) | 7501
32 bit CONNX Rest Server | 9500
64 bit CONNX Rest Server | 9502

If CONNX is installed in an environment where a firewall is present, these ports must be open.
If you need to change the default 64 bit CONNX Rest Server port, we do not recommend using port 9501.
