Hello m0n0-community,

I am a student and setting up the (intranet) router (m0n0) for our 
school network.
You can find a network outline here:

But I'm not exactly sure how to set up the firewall rule on the m0n0 box 
set in order to fit my needs:

   * Allowing Traffic from the classroom subnets (205,202,204,210) to 
the backbone
   * Blocking Traffic between the subnets (e.g. 192.168.202.0/24 cannot
     access 192.168.168.204.0/24)
   * Allowing DNS, HTTP(S) from the WAN interface.

Is it a good idea to also NAT the classroom subnets 205,202,204,210 ?

I'm looking forward for your ideas and suggestions!

Thanks!

Greetings
