Acessing UNA from a device (mobile, another PC, etc.) on a local network

When I try to access UNA installation from another device on the local network, the IP address of the installation device (typically numbers (192...), v.g., is translated (automatically)  for UNA to letters (local...). I.e, numbers(192...) become letters(local...). This way throwing a browser error: ERR_CONNECTION_REFUSED.

How to setup UNA for this access type?

Thanks.
