Network requirements

Is a firewall active in 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 CUBE)
  • Please enable port 443 towards the Internet - for encrypted communication to the Internet
  • Please enable the NTP protocol (UDP port 123) towards the Internet - for time synchronization


Internet Settings

Priority Port Protocol Protocol Name Description
required 123 UDP NTP Access to the time server the dhcp server provides - without NTP no secure connections can be established because certificates can not be validated.
required 53 UDP DNS Domain Name Service - name resolution on the Internet. This protocol is used to resolve Internet addresses (e.g. https:// * into IP addresses.
required 443 TCP HTTPS Encrypted connection to the Internet. Required for connecting the tapio Cloud and the HOMAG Cloud Services.
optional* 13 ICMP ICMP Outgoing pings are required for checking the connection to the tapio cloud.

* optional: These ports are not required for CUBES operation and are used for diagnostics and analysis in support cases.

Settings for the local (internal) network

The HOMAG CUBE has several diagnostic services that should be accessible in the local network. It is recommended that these services only be available in the local / internal network.

Priority Port Protocol Protocol Name Description
required 80 (45001) TCP HTTP

Diagnostic page of the HOMAG CUBE

required 5555 TCP HTTP

Local diagnostic page of the tapio Cloud-Connector

optional* 5353 UDP MDNS

Multicast DNS-Deamon to provide 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 is allowed per second!

optional* 22 TCP SSH

The ssh daemon is deactivated by default and needs to be activated manually using the diagnostics webinterface. In cases of local and remote servicing the service stuff can activate the feature manually. If the ssh daemon is activated the status is shown in the diagnostic pages and on the status icon.

* optional: These ports are not required for CUBES operation and are used for diagnostics and analysis in support cases.
