### Network requirements

There are a few prerequisites and things you’ll need before the installation:

* The installation will temporarily boot up a webserver on a random port for the web-based installation. Be sure this port is open in the firewall. It is also possible to define your own port. 
* Permissions: sudo privileges are necessary for executing installation commands.
* We require internet access during the installation procedure.
