Ports Used by Third-Party Components
Third-party components such as PostgreSQL and LDAP use a number of ports for associated services.
In the following table, the Access Requirement column for each port is usually either "Internal" or "External." In this context, "Internal" means that the port is used only for communication among the components; "External" means that the port can be used for either internal or external communication.
