ADSelfservice Plus - GINA installation: The network path was not found.

Hello,

We tried to install GINA on the endpoint what is located in a different ip range than ADSelfService Plus server. We allowed port 8888 and 9251 from the endpoint to the server on firewall device. And, GINA installation completed with error "The network path was not found".
which other port(s) (connection) do we have to allow on firewall device?

Thank you.
