I tried doing this by changing the mask, but now that I think about it broadcast would be different for each net.
So to clearify net 1 devices can talk to each other but not net 2, net 2 devices can talk to net 1 and net 2.
was using class c 192.168.0.xxx/24 for net 1
was using class c 192.168.yyy.xxx/16 for net 2
What is the proper way to implement this?
