When I install Astaro, it asks me if want to install Astaro components or only the GPL ones. I wonder what features other than the great interface are not installed and if there is any documentation of the Astaro GPL 'only' installation
if you install GPLed part only, installation will surely not end up in a working firewall. Afaik there is no Astaro GPL documentation since it is not needed. Think the choice during the install procedure is nescessary not to break any kind of license.
