The default ports are 80 for HTTP and 443 for HTTPS, but you can configure any ports you wish in IIS.
If an interface is separated from its endpoint connection, then the port used by the interface will need to be opened between the Transpara Web server and the data source.
For example (using OSIsoft PI as the data source), if there is a firewall between the Transpara Web server and PI server(s), you will need to open port 5450 for inbound traffic to OSI PI coming from our use of the PI or AF SDK.
If you need help with a specific scenario or data source, please contact us.
