Make sure the following ports are open on any firewalls in use on machines/devices running Prism.
Program
Open Port Requirement
Apache
80 and 443
Oracle
1521
Prism License Server
6470
Prism Proxy
443 (outgoing connection to Apache) and 8080-8089 (configurable, depends on number of Proxies)
Centrals
80 (v2.0 and later)
50025 (v1.14.7 and earlier)
In Prism 2.x, the dedicated Centrals service is removed and instead Centrals is handled by the POSv1 and Common services. Prism 2.x doesn't require a specific port to be open EXCEPT port 80 on the store web server. If port 80 on the store web server is not open or is being used by something else, Prism and the Centrals Server will be unable to establish connectivity through a REST connection.
In Prism 1.14.7 and earlier, there is a dedicated Centrals service that uses port 50025 and requires it be open. The Centrals server should be at the root installation, not at the store, so in Prism 1.14.7, port 50025 should be open at the ROOT level. There is no need to keep port 50025 open on the Prism 1.14.7 store network.
