@6rilT You would install the accesscontrol plugin, and then configure it. Here’s information on it: https://forums.fogproject.org/topic/9624/control-access-plugin/7
I don’t k now if @Fernando-Gietz completed the Site control plugin, but information on that is here: https://forums.fogproject.org/topic/9902/site-plugin
If you are not familiar with fog’s plugins, you have to enable the plugin system in FOG Configuration - it’s just a checkbox, click save. You’ll get a new item in the fog ribbon for plugins. From there, you can install any of the available plugins.
