# Network requirements

Is there a firewall active on your network? If so, please check the following network requirements with your network administrator:

- Please activate a DHCP server in the network – for automatic network integration (IP address assignment for the )
- Please enable port 443 in the direction of the Internet – for encrypted communication to the Internet
- Please enable the NTP protocol (UDP port 123) to the Internet – for time synchronization

## Internet Settings

| Priority | Port | Protocol | Protocol Name | Description |
| --- | --- | --- | --- | --- |
| **required** | 123 | UDP | NTP | Access to the time server provided by the dhcp server - without NTP, no secure connections can be established because certificates cannot be validated. |
| **required** | 53 | UDP | DNS | Domain Name Service – name resolution on the Internet. With this protocol, Internet addresses (e.g. https:// *.tapio.one/) are resolved into IP addresses. |
| **required** | 443 | TCP | HTTPS | Encrypted connection to the Internet. Required to connect the tapio Cloud and the HOMAG Cloud Services. |
| **optional*** | 13 | ICMP | ICMP | Outgoing pings are required to verify the connection to the tapio Cloud. |

* Optional: These ports are not required for the operation of the CUBE and are used for diagnostics and analysis in support cases.

## Settings for the internal network

The HOMAG CUBE has various diagnostic services that should be accessible in the local network. We recommend that you make these services available only on the internal network.

| Priority | Port | Protocol | Name of the protocol | Description |
| --- | --- | --- | --- | --- |
| **required** | 80 (45001) | TCP | HTTP | Tapio Cloud Connector Local Diagnostics Page |
| **required** | 5555 | TCP | HTTP | Cloud Connector Diagnostics Page |
| **optional*** | 5353 | UDP | mDNS | Multicast DNS service for providing the HOMAG Cube name in the local network |
| **optional*** | 5355 | UDP | LLMNR | Link-Local Multicast Name Resolution; allows hosts to perform name resolution for devices on the same LAN. |
| **optional*** | 13 | ICMP | ICMP | Incoming pings to check if the CUBE is online - Attention: Only one ping per second is allowed! |
| **optional*** | 22 | TCP | SSH | The SSH service is disabled by default and must be enabled manually through the Diagnostic Web Interface. In the case of local maintenance or remote maintenance, the service employee can activate the function manually. When the SSH service is enabled, the status is displayed in the diagnostic pages and via the status light |

* Optional: These ports are not required for the operation of the CUBE and are used for diagnostics and analysis in support cases.
