Question: How to restrict access to a specific IP per folder

[merlinuwe]

I remember - many years ago - when I was using HFS there was an option to allow to access a folder only from a given IP-address. I searched in the latest release candidate of today, but did not find this anymore. Is there a solution?

Background: I'd like to use this software (again) in a classroom, where are 25 computers for pupils and 1 for me, the teacher.

Example:

Place 1 with IP 10.10.304.1 should have only access to the folder "Platz_01" and the folder "Platz_99", where the teacher gives (only) download-access to some files/folders to everyone without any permission. (The pupils should not need an account. No pupil should be able to access the account of an other pupil. ;-))

Place 2 with IP 10.10.304.2 should have only access to the folder "Platz_02" and the folder "Platz_99" and so on.

(The teacher can zip the whole folders after the pupils work is done.)
