First of all, sorry for the late reply,
I have a basic knowledge of IP addresses etc., and I don’t have much knowledge of firewalls yet. That’s why I wanted to start with a little experiment. The “server” is a small Raspberry P4 Nextcloud server, so small and nothing important. Only cell phone pictures are saved on it.
And yes, it is actually normal for a firewall to protect the internal network from the external network (Internet). I just want to build a small config to understand it. Hence the post here. I roughly drew a picture again of what it looks like to me.
If you could roughly describe to me how I should set the IP addresses on the Ipfire as well as the address of the server and the workstations.
Thank you in advance,
