Internal network
The following ports are required for server to server communication. The Relution service uses these ports to communicate with external services (Database, Directory service, Mail server). The exact configuration you need depends on the services you use and whether services are run on separate servers (recommended). If servers are located on the same network no additional firewall configuration should be needed. All ports are TCP.
