Hi,
In our local school we have two servers and roughly 80 clients. The
network is 192.168.10.0/255.255.255.0, and DHCP+DNS is managed by Dnsmasq.
School PCs (teachers and management) are registered via MAC address and
get an IP address in a specific range:
192.168.10.2 - 192.168.10.50 - management + teachers
192.168.10.201 - 192.168.10.220 - computer room
192.168.10.246 - 192.168.10.247 - printers
192.168.10.251 - 192.168.10.253 - wireless access points
If a client (like a student's laptop, tablet or smartphone) is not
registered, it gets an IP address in the range between 192.168.10.100
and 192.168.10.200.
Up until recently I've been using a combination of Squid and Squidguard
to filter Internet access.
This year the school's director wants to completely block Internet
access for all the student's personal devices.
The Linux server acts as a transparent gateway. Unfortunately with Squid
I can only filter/block HTTP connections, but not HTTPS (well, I could,
but this is way too complicated to setup).
The firewall is managed by a simple Iptables script. Now I *think* the
easiest way to block a certain IP range from Internet access would be
through Iptables (correct me if I'm wrong). If this is the case, what
would that look like?
Any suggestions?
