System requirements
The following hardware and software requirements must be met, to install and operate a Relution server.
Minimum hardware requirements
The following hardware is required to run a Relution server required:
- 2 CPU cores
- 4 GiB RAM
- 1 network card
- 10 GiB HDD/SSD
- Additional storage space for user data, operating system and other applications and programs
External resource storage
We recommend using an external resource storage in generel, especially in these cases:
- Installation and management of native apps on Windows devices
- If native apps larger than 50 MB or in general a lot of native apps are used

Firewall configuration
Internet access
The following ports must be opened on the firewall for incoming and outgoing connections from/to the internet. All ports except UDP 123 are TCP ports.
| Port | Direction | Source | Required | Description |
|---|---|---|---|---|
| 80 | Inbound | All | Yes | Redirect to HTTPS |
| 443 | Inbound | All | Yes | For internet access and client to server communication |
| 7800 | In-/Outbound | Cluster node | Yes | Necessary for the communication between cluster nodes |
| 8099 | Inbound | Local network | No | Necessary for Health Status Monitoring |
| 2197 | Inbound | Associated/Appointed | No¹ | Apple Push Notification Services (APNS) |
| 80 | Outbound | - | Yes | Redirect to HTTPS |
| 443 | Outbound | - | Yes | e.g. SMS service, license server, VPP, DEP, … |
| 2197 | Outbound | - | No¹ | Apple Push Notification Services (APNS) |
| 123 UDP | Outbound | - | Yes | NTP (time server) |
Mobile devices
When mobile devices are connected to the internal network (Wi-Fi), additional inbound and outbound ports have to be opened so that devices to connect to the Apple and/or Google servers in order to receive push to receive push messages. When the devices are connected to mobile data, no additional configuration should be required. All ports are TCP.
| Port | Direction | Source | Required | Description |
|---|---|---|---|---|

Internal network
The Relution service uses these ports to communicate with external services (database, directory service, mail server). The exact configuration depends on which services are used and whether the services run on separate servers (recommended).
If the servers servers are on the same network, no additional firewall configuration should be required. All ports are TCP.
| Port | Description |
|---|---|
| 25 | Mail server (SMTP) |
| 389 | Directory service (LDAP) |
| 587 | Mail server (SMTPS) |
| 636 | Directory Service (LDAPS) |
| 3306 | MariaDB/MySQL |
| 5432 | PostgreSQL |
